X vs. Wayland Architecture A good way to understand the Wayland architecture and how it is different from X is to follow an event from the input device to the point where the change it affects appears on screen. This is where we are now with X:
X architecture diagram
The kernel gets an event from an input device and sends it to X through the evdev input driver. The kernel does all the hard work here by driving the device and translating the different device specific event protocols to the linux evdev input event standard. The X server determines which window the event affects and sends it to the clients that have selected for the event in question on that window. The X server doesn't actually know how to do this right, since the window location on screen is controlled by the compositor and may be transformed in a number of ways that the X server doesn't understand (scaled down, rotated, wobbling, etc). The client looks at the event and decides what to do. Often the UI will have to change in response to the event - perhaps a check box was clicked or the pointer entered a button that must be highlighted. Thus the client sends a rendering request back to the X server. When the X server receives the rendering request, it sends it to the driver to let it program the hardware to do the rendering. The X server also calculates the bounding region of the rendering, and sends that to the compositor as a damage event. The damage event tells the compositor that something changed in the window and that it has to recomposite the part of the screen where that window is visible. The compositor is responsible for rendering the entire screen contents based on its scenegraph and the contents of the X windows. Yet, it has to go through the X server to render this. The X server receives the rendering requests from the compositor and either copies the compositor back buffer to the front buffer or does a pageflip. In the general case, the X server has to do this step so it can account for overlapping windows, which may require clipping and determine whether or not it can page flip. However, for a compositor, which is always fullscreen, this is another unnecessary context switch. As suggested above, there are a few problems with this approach. The X server doesn't have the information to decide which window should receive the event, nor can it transform the screen coordinates to window-local coordinates. And even though X has handed responsibility for the final painting of the screen to the compositing manager, X still controls the front buffer and modesetting. Most of the complexity that the X server used to handle is now available in the kernel or self contained libraries (KMS, evdev, mesa, fontconfig, freetype, cairo, Qt etc). In general, the X server is now just a middle man that introduces an extra step between applications and the compositor and an extra step between the compositor and the hardware. In Wayland the compositor is the display server. We transfer the control of KMS and evdev to the compositor. The Wayland protocol lets the compositor send the input events directly to the clients and lets the client send the damage event directly to the compositor:
Wayland architecture diagram
The kernel gets an event and sends it to the compositor. This is similar to the X case, which is great, since we get to reuse all the input drivers in the kernel. The compositor looks through its scenegraph to determine which window should receive the event. The scenegraph corresponds to what's on screen and the compositor understands the transformations that it may have applied to the elements in the scenegraph. Thus, the compositor can pick the right window and transform the screen coordinates to window-local coordinates, by applying the inverse transformations. The types of transformation that can be applied to a window is only restricted to what the compositor can do, as long as it can compute the inverse transformation for the input events. As in the X case, when the client receives the event, it updates the UI in response. But in the Wayland case, the rendering happens in the client, and the client just sends a request to the compositor to indicate the region that was updated. The compositor collects damage requests from its clients and then recomposites the screen. The compositor can then directly issue an ioctl to schedule a pageflip with KMS.
Wayland Rendering One of the details I left out in the above overview is how clients actually render under Wayland. By removing the X server from the picture we also removed the mechanism by which X clients typically render. But there's another mechanism that we're already using with DRI2 under X: direct rendering. With direct rendering, the client and the server share a video memory buffer. The client links to a rendering library such as OpenGL that knows how to program the hardware and renders directly into the buffer. The compositor in turn can take the buffer and use it as a texture when it composites the desktop. After the initial setup, the client only needs to tell the compositor which buffer to use and when and where it has rendered new content into it. This leaves an application with two ways to update its window contents: Render the new content into a new buffer and tell the compositor to use that instead of the old buffer. The application can allocate a new buffer every time it needs to update the window contents or it can keep two (or more) buffers around and cycle between them. The buffer management is entirely under application control. Render the new content into the buffer that it previously told the compositor to to use. While it's possible to just render directly into the buffer shared with the compositor, this might race with the compositor. What can happen is that repainting the window contents could be interrupted by the compositor repainting the desktop. If the application gets interrupted just after clearing the window but before rendering the contents, the compositor will texture from a blank buffer. The result is that the application window will flicker between a blank window or half-rendered content. The traditional way to avoid this is to render the new content into a back buffer and then copy from there into the compositor surface. The back buffer can be allocated on the fly and just big enough to hold the new content, or the application can keep a buffer around. Again, this is under application control. In either case, the application must tell the compositor which area of the surface holds new contents. When the application renders directly to the shared buffer, the compositor needs to be noticed that there is new content. But also when exchanging buffers, the compositor doesn't assume anything changed, and needs a request from the application before it will repaint the desktop. The idea that even if an application passes a new buffer to the compositor, only a small part of the buffer may be different, like a blinking cursor or a spinner.
Hardware Enabling for Wayland Typically, hardware enabling includes modesetting/display and EGL/GLES2. On top of that Wayland needs a way to share buffers efficiently between processes. There are two sides to that, the client side and the server side. On the client side we've defined a Wayland EGL platform. In the EGL model, that consists of the native types (EGLNativeDisplayType, EGLNativeWindowType and EGLNativePixmapType) and a way to create those types. In other words, it's the glue code that binds the EGL stack and its buffer sharing mechanism to the generic Wayland API. The EGL stack is expected to provide an implementation of the Wayland EGL platform. The full API is in the wayland-egl.h header. The open source implementation in the mesa EGL stack is in wayland-egl.c and platform_wayland.c. Under the hood, the EGL stack is expected to define a vendor-specific protocol extension that lets the client side EGL stack communicate buffer details with the compositor in order to share buffers. The point of the wayland-egl.h API is to abstract that away and just let the client create an EGLSurface for a Wayland surface and start rendering. The open source stack uses the drm Wayland extension, which lets the client discover the drm device to use and authenticate and then share drm (GEM) buffers with the compositor. The server side of Wayland is the compositor and core UX for the vertical, typically integrating task switcher, app launcher, lock screen in one monolithic application. The server runs on top of a modesetting API (kernel modesetting, OpenWF Display or similar) and composites the final UI using a mix of EGL/GLES2 compositor and hardware overlays if available. Enabling modesetting, EGL/GLES2 and overlays is something that should be part of standard hardware bringup. The extra requirement for Wayland enabling is the EGL_WL_bind_wayland_display extension that lets the compositor create an EGLImage from a generic Wayland shared buffer. It's similar to the EGL_KHR_image_pixmap extension to create an EGLImage from an X pixmap. The extension has a setup step where you have to bind the EGL display to a Wayland display. Then as the compositor receives generic Wayland buffers from the clients (typically when the client calls eglSwapBuffers), it will be able to pass the struct wl_buffer pointer to eglCreateImageKHR as the EGLClientBuffer argument and with EGL_WAYLAND_BUFFER_WL as the target. This will create an EGLImage, which can then be used by the compositor as a texture or passed to the modesetting code to use as an overlay plane. Again, this is implemented by the vendor specific protocol extension, which on the server side will receive the driver specific details about the shared buffer and turn that into an EGL image when the user calls eglCreateImageKHR.

Introduction The open-source reference implementation of Wayland protocol is split in two C libraries, libwayland-client and libwayland-server. Their main responsibility is to handle the Inter-process communication (IPC) with each other, therefore guaranteeing the protocol objects marshaling and messages synchronization. A client uses libwayland-client to communicate with one or more wayland servers. A wl_display object is created and manages each open connection to a server. At least one wl_event_queue object is created for each wl_display, this holds events as they are received from the server until they can be processed. Multi-threading is supported by creating an additional wl_event_queue for each additional thread, each object can have it's events placed in a particular queue, so potentially a different thread could be made to handle the events for each object created. Though some convenience functions are provided, libwayland-client is designed to allow the calling code to wait for events, so that different polling mechanisms can be used. A file descriptor is provided, when it becomes ready for reading the calling code can ask libwayland-client to read the available events from it into the wl_event_queue objects. The library only provides low-level access to the wayland objects. Each object created by the client is represented by a wl_proxy object that this library creates. This includes the id that is actually communicated over the socket to the server, a void* data pointer that is intended to point at a client's representation of the object, and a pointer to a static wl_interface object, which is generated from the xml and identifies the object's class and can be used for introspection into the messages and events. Messages are sent by calling wl_proxy_marshal. This will write a message to the socket, by using the message id and the wl_interface to identify the types of each argument and convert them into stream format. Most software will call type-safe wrappers generated from the xml description of the Wayland protocols. For instance the C header file generated from the xml defines the following inline function to transmit the wl_surface::attach message: static inline void wl_surface_attach(struct wl_surface *wl_surface, struct wl_buffer *buffer, int32_t x, int32_t y) { wl_proxy_marshal((struct wl_proxy *) wl_surface, WL_SURFACE_ATTACH, buffer, x, y); } Events (messages from the server) are handled by calling a "dispatcher" callback the client stores in the wl_proxy for each event. A language binding for a string-based interpreter, such as CPython, might have a dispatcher that uses the event name from the wl_interface to identify the function to call. The default dispatcher uses the message id number to index an array of functions pointers, called a wl_listener, and the wl_interface to convert data from the stream into arguments to the function. The C header file generated from the xml defines a per-class structure that forces the function pointers to be of the correct type, for instance the wl_surface::enter event defines this pointer in the wl_surface_listener object: struct wl_surface_listener { void (*enter)(void *data, struct wl_surface *, struct wl_output *); ... }

]> X11 Application Support
Introduction Being able to run existing X11 applications is crucial for the adoption of Wayland, especially on desktops, as there will always be X11 applications that have not been or cannot be converted into Wayland applications, and throwing them all away would be prohibitive. Therefore a Wayland compositor often needs to support running X11 applications. X11 and Wayland are different enough that there is no "simple" way to translate between them. Most of X11 is uninteresting to a Wayland compositor. That, combined with the gigantic implementation effort needed to support X11, makes it intractable to just write X11 support directly in a Wayland compositor. The implementation would be nothing short of a real X11 server. Therefore, Wayland compositors should use Xwayland, the X11 server that lives in the Xorg server source code repository and shares most of the implementation with the Xorg server. Xwayland is a complete X11 server, just like Xorg is, but instead of driving the displays and opening input devices, it acts as a Wayland client. The rest of this chapter talks about how Xwayland works. For integration and architecture reasons, while Xwayland is a Wayland client of the Wayland compositor, the Wayland compositor is an X11 client of Xwayland. This circular dependency requires special care from the Wayland compositor.
Two Modes for Foreign Windows In general, windows from a foreign window system can be presented in one of two ways: rootless and rootful (not rootless). In rootful mode, the foreign window system as a whole is represented as a window (or more) of its own. You have a native window, inside which all the foreign windows are. The advantage of this approach in Xwayland's case is that you can run your favourite X11 window manager to manage your X11 applications. The disadvantage is that the foreign windows do not integrate with the native desktop. Therefore this mode is not usually used. In rootless mode, each foreign window is a first-class resident among the native windows. Foreign windows are not confined inside a native window but act as if they were native windows. The advantage is that one can freely stack and mix native and foreign windows, which is not possible in rootful mode. The disadvantage is that this mode is harder to implement and fundamental differences in window systems may prevent some things from working. With rootless Xwayland, the Wayland compositor must take the role as the X11 window manager, and one cannot use any other X11 window manager in its place. This chapter concentrates on the rootless mode, and ignores the rootful mode.
Architecture A Wayland compositor usually takes care of launching Xwayland. Xwayland works in cooperation with a Wayland compositor as follows:
Xwayland architecture diagram
An X11 application connects to Xwayland just like it would connect to any X server. Xwayland processes all the X11 requests. On the other end, Xwayland is a Wayland client that connects to the Wayland compositor. The X11 window manager (XWM) is an integral part of the Wayland compositor. XWM uses the usual X11 window management protocol to manage all X11 windows in Xwayland. Most importantly, XWM acts as a bridge between Xwayland window state and the Wayland compositor's window manager (WWM). This way WWM can manage all windows, both native Wayland and X11 (Xwayland) windows. This is very important for a coherent user experience. Since Xwayland uses Wayland for input and output, it does not have any use for the device drivers that Xorg uses. None of the xf86-video-* or xf86-input-* modules are used. There also is no configuration file for the Xwayland server. For optional hardware accelerated rendering, Xwayland uses GLAMOR. A Wayland compositor usually spawns only one Xwayland instance. This is because many X11 applications assume they can communicate with other X11 applications through the X server, and this requires a shared X server instance. This also means that Xwayland does not protect nor isolate X11 clients from each other, unless the Wayland compositor specifically chooses to break the X11 client intercommunications by spawning application specific Xwayland instances. X11 clients are naturally isolated from Wayland clients. Xwayland compatibility compared to a native X server will probably never reach 100%. Desktop environment (DE) components, specifically X11 window managers, are practically never supported. An X11 window manager would not know about native Wayland windows, so it could manage only X11 windows. On the other hand, there must be an XWM that reserves the exclusive window manager role so that the Wayland compositor could show the X11 windows appropriately. For other DE components, like pagers and panels, adding the necessary interfaces to support them in WWM through XWM is often considered not worthwhile.
X Window Manager (XWM) From the X11 point of view, the X window manager (XWM) living inside a Wayland compositor is just like any other window manager. The difference is mostly in which process it resides in, and the few extra conventions in the X11 protocol to support Wayland window management (WWM) specifically. There are two separate asynchronous communication channels between Xwayland and a Wayland compositor: one uses the Wayland protocol, and the other one, solely for XWM, uses X11 protocol. This setting demands great care from the XWM implementation to avoid (random) deadlocks with Xwayland. It is often nearly impossible to prove that synchronous or blocking X11 calls from XWM cannot cause a deadlock, and therefore it is strongly recommended to make all X11 communications asynchronous. All Wayland communications are already asynchonous by design.
Window identification In Xwayland, an X11 window may have a corresponding wl_surface object in Wayland. The wl_surface object is used for input and output: it is referenced by input events and used to provide the X11 window content to the Wayland compositor. The X11 window and the wl_surface live in different protocol streams, and they need to be matched for XWM to do its job. When Xwayland creates a wl_surface on Wayland, it will also send an X11 ClientMessage of type atom "WL_SURFACE_ID" to the X11 window carrying the wl_surface Wayland object ID as the first 32-bit data element. This is how XWM can associate a wl_surface with an X11 window. Note that the request to create a wl_surface and the ID message may arrive in any order in the Wayland compositor.

The clients can be traditional applications, X servers (rootless or fullscreen) or other display servers.

Motivation Most Linux and Unix-based systems rely on the X Window System (or simply X) as the low-level protocol for building bitmap graphics interfaces. On these systems, the X stack has grown to encompass functionality arguably belonging in client libraries, helper libraries, or the host operating system kernel. Support for things like PCI resource management, display configuration management, direct rendering, and memory management has been integrated into the X stack, imposing limitations like limited support for standalone applications, duplication in other projects (e.g. the Linux fb layer or the DirectFB project), and high levels of complexity for systems combining multiple elements (for example radeon memory map handling between the fb driver and X driver, or VT switching). Moreover, X has grown to incorporate modern features like offscreen rendering and scene composition, but subject to the limitations of the X architecture. For example, the X implementation of composition adds additional context switches and makes things like input redirection difficult. X architecture diagram The diagram above illustrates the central role of the X server and compositor in operations, and the steps required to get contents on to the screen. Over time, X developers came to understand the shortcomings of this approach and worked to split things up. Over the past several years, a lot of functionality has moved out of the X server and into client-side libraries or kernel drivers. One of the first components to move out was font rendering, with freetype and fontconfig providing an alternative to the core X fonts. Direct rendering OpenGL as a graphics driver in a client side library went through some iterations, ending up as DRI2, which abstracted most of the direct rendering buffer management from client code. Then cairo came along and provided a modern 2D rendering library independent of X, and compositing managers took over control of the rendering of the desktop as toolkits like GTK+ and Qt moved away from using X APIs for rendering. Recently, memory and display management have moved to the Linux kernel, further reducing the scope of X and its driver stack. The end result is a highly modular graphics stack.
The compositing manager as the display server Wayland is a new display server and compositing protocol, and Weston is the implementation of this protocol which builds on top of all the components above. We are trying to distill out the functionality in the X server that is still used by the modern Linux desktop. This turns out to be not a whole lot. Applications can allocate their own off-screen buffers and render their window contents directly, using hardware accelerated libraries like libGL, or high quality software implementations like those found in Cairo. In the end, what’s needed is a way to present the resulting window surface for display, and a way to receive and arbitrate input among multiple clients. This is what Wayland provides, by piecing together the components already in the eco-system in a slightly different way. X will always be relevant, in the same way Fortran compilers and VRML browsers are, but it’s time that we think about moving it out of the critical path and provide it as an optional component for legacy applications. Overall, the philosophy of Wayland is to provide clients with a way to manage windows and how their contents is displayed. Rendering is left to clients, and system wide memory management interfaces are used to pass buffer handles between clients and the compositing manager. Wayland architecture diagram The figure above illustrates how Wayland clients interact with a Wayland server. Note that window management and composition are handled entirely in the server, significantly reducing complexity while marginally improving performance through reduced context switching. The resulting system is easier to build and extend than a similar X system, because often changes need only be made in one place. Or in the case of protocol extensions, two (rather than 3 or 4 in the X case where window management and/or composition handling may also need to be updated).

For instance, a system compositor can be used for booting the system, handling multiple user switching, a possible console terminal emulator and so forth. A different compositor, a session compositor would provide the actual desktop environment. There are many ways for different types of compositors to co-exist. In this section, we introduce three types of Wayland compositors relying on libwayland-server.
System Compositor A system compositor can run from early boot until shutdown. It effectively replaces the kernel vt system, and can tie in with the systems graphical boot setup and multiseat support. A system compositor can host different types of session compositors, and let us switch between multiple sessions (fast user switching, or secure/personal desktop switching). A linux implementation of a system compositor will typically use libudev, egl, kms, evdev and cairo. For fullscreen clients, the system compositor can reprogram the video scanout address to read directly from the client provided buffer.
Session Compositor A session compositor is responsible for a single user session. If a system compositor is present, the session compositor will run nested under the system compositor. Nesting is feasible because the protocol is asynchronous; roundtrips would be too expensive when nesting is involved. If no system compositor is present, a session compositor can run directly on the hardware. X applications can continue working under a session compositor by means of a root-less X server that is activated on demand. Possible examples for session compositors include gnome-shell moblin kwin kmscon rdp session Weston with X11 or Wayland backend is a session compositor nested in another session compositor. fullscreen X session under Wayland
Embedding Compositor X11 lets clients embed windows from other clients, or lets clients copy pixmap contents rendered by another client into their window. This is often used for applets in a panel, browser plugins and similar. Wayland doesn't directly allow this, but clients can communicate GEM buffer names out-of-band, for example, using D-Bus, or command line arguments when the panel launches the applet. Another option is to use a nested Wayland instance. For this, the Wayland server will have to be a library that the host application links to. The host application will then pass the Wayland server socket name to the embedded application, and will need to implement the Wayland compositor interface. The host application composites the client surfaces as part of it's window, that is, in the web page or in the panel. The benefit of nesting the Wayland server is that it provides the requests the embedded client needs to inform the host about buffer updates and a mechanism for forwarding input events from the host application. An example for this kind of setup is firefox embedding the flash player as a kind of special-purpose compositor.

Introduction The open-source reference implementation of Wayland protocol is split in two C libraries, libwayland-client and libwayland-server. Their main responsibility is to handle the Inter-process communication (IPC) with each other, therefore guaranteeing the protocol objects marshaling and messages synchronization. The server library is designed to work much like libwayland-client, although it is considerably complicated due to the server needing to support multiple versions of the protocol. It is best to learn libwayland-client first. Each open socket to a client is represented by a wl_client. The equvalent of the wl_proxy that libwayland-client uses to represent an object is wl_resource for client-created objects, and wl_global for objects created by the server. Often a server is also a client for another Wayland server, and thus must link with both libwayland-client and libwayland-server. This produces some type name conflicts (such as the client wl_display and server wl_display, but the duplicate-but-not-the-same types are opaque, and accessed only inside the correct library where it came from. Naturally that means that the program writer needs to always know if a pointer to a wl_display is for the server or client side and use the corresponding functions.

Basic Principles The Wayland protocol is an asynchronous object oriented protocol. All requests are method invocations on some object. The requests include an object ID that uniquely identifies an object on the server. Each object implements an interface and the requests include an opcode that identifies which method in the interface to invoke. The protocol is message-based. A message sent by a client to the server is called request. A message from the server to a client is called event. A message has a number of arguments, each of which has a certain type (see for a list of argument types). Additionally, the protocol can specify enums which associate names to specific numeric enumeration values. These are primarily just descriptive in nature: at the wire format level enums are just integers. But they also serve a secondary purpose to enhance type safety or otherwise add context for use in language bindings or other such code. This latter usage is only supported so long as code written before these attributes were introduced still works after; in other words, adding an enum should not break API, otherwise it puts backwards compatibility at risk. enums can be defined as just a set of integers, or as bitfields. This is specified via the bitfield boolean attribute in the enum definition. If this attribute is true, the enum is intended to be accessed primarily using bitwise operations, for example when arbitrarily many choices of the enum can be ORed together; if it is false, or the attribute is omitted, then the enum arguments are a just a sequence of numerical values. The enum attribute can be used on either uint or int arguments, however if the enum is defined as a bitfield, it can only be used on uint args. The server sends back events to the client, each event is emitted from an object. Events can be error conditions. The event includes the object ID and the event opcode, from which the client can determine the type of event. Events are generated both in response to requests (in which case the request and the event constitutes a round trip) or spontaneously when the server state changes. State is broadcast on connect, events are sent out when state changes. Clients must listen for these changes and cache the state. There is no need (or mechanism) to query server state. The server will broadcast the presence of a number of global objects, which in turn will broadcast their current state.
Code Generation The interfaces, requests and events are defined in protocol/wayland.xml. This xml is used to generate the function prototypes that can be used by clients and compositors. The protocol entry points are generated as inline functions which just wrap the wl_proxy_* functions. The inline functions aren't part of the library ABI and language bindings should generate their own stubs for the protocol entry points from the xml.
Wire Format The protocol is sent over a UNIX domain stream socket, where the endpoint usually is named wayland-0 (although it can be changed via WAYLAND_DISPLAY in the environment). Beginning in Wayland 1.15, implementations can optionally support server socket endpoints located at arbitrary locations in the filesystem by setting WAYLAND_DISPLAY to the absolute path at which the server endpoint listens. Every message is structured as 32-bit words; values are represented in the host's byte-order. The message header has 2 words in it: The first word is the sender's object ID (32-bit). The second has 2 parts of 16-bit. The upper 16-bits are the message size in bytes, starting at the header (i.e. it has a minimum value of 8).The lower is the request/event opcode. The payload describes the request/event arguments. Every argument is always aligned to 32-bits. Where padding is required, the value of padding bytes is undefined. There is no prefix that describes the type, but it is inferred implicitly from the xml specification. The representation of argument types are as follows: int uint The value is the 32-bit value of the signed/unsigned int. fixed Signed 24.8 decimal numbers. It is a signed decimal type which offers a sign bit, 23 bits of integer precision and 8 bits of decimal precision. This is exposed as an opaque struct with conversion helpers to and from double and int on the C API side. string Starts with an unsigned 32-bit length, followed by the string contents, including terminating null byte, then padding to a 32-bit boundary. object 32-bit object ID. new_id The 32-bit object ID. Generally, the interface used for the new object is inferred from the xml, but in the case where it's not specified, a new_id is preceeded by a string specifying the interface name, and a uint specifying the version. array Starts with 32-bit array size in bytes, followed by the array contents verbatim, and finally padding to a 32-bit boundary. fd The file descriptor is not stored in the message buffer, but in the ancillary data of the UNIX domain socket message (msg_control).
Versioning Every interface is versioned and every protocol object implements a particular version of its interface. For global objects, the maximum version supported by the server is advertised with the global and the actual version of the created protocol object is determined by the version argument passed to wl_registry.bind(). For objects that are not globals, their version is inferred from the object that created them. In order to keep things sane, this has a few implications for interface versions: The object creation hierarchy must be a tree. Otherwise, infering object versions from the parent object becomes a much more difficult to properly track. When the version of an interface increases, so does the version of its parent (recursively until you get to a global interface) A global interface's version number acts like a counter for all of its child interfaces. Whenever a child interface gets modified, the global parent's interface version number also increases (see above). The child interface then takes on the same version number as the new version of its parent global interface. To illustrate the above, consider the wl_compositor interface. It has two children, wl_surface and wl_region. As of wayland version 1.2, wl_surface and wl_compositor are both at version 3. If something is added to the wl_region interface, both wl_region and wl_compositor will get bumpped to version 4. If, afterwards, wl_surface is changed, both wl_compositor and wl_surface will be at version 5. In this way the global interface version is used as a sort of "counter" for all of its child interfaces. This makes it very simple to know the version of the child given the version of its parent. The child is at the highest possible interface version that is less than or equal to its parent's version. It is worth noting a particular exception to the above versioning scheme. The wl_display (and, by extension, wl_registry) interface cannot change because it is the core protocol object and its version is never advertised nor is there a mechanism to request a different version.
Connect Time There is no fixed connection setup information, the server emits multiple events at connect time, to indicate the presence and properties of global objects: outputs, compositor, input devices.
Security and Authentication mostly about access to underlying buffers, need new drm auth mechanism (the grant-to ioctl idea), need to check the cmd stream? getting the server socket depends on the compositor type, could be a system wide name, through fd passing on the session dbus. or the client is forked by the compositor and the fd is already opened.
Creating Objects Each object has a unique ID. The IDs are allocated by the entity creating the object (either client or server). IDs allocated by the client are in the range [1, 0xfeffffff] while IDs allocated by the server are in the range [0xff000000, 0xffffffff]. The 0 ID is reserved to represent a null or non-existant object. For efficiency purposes, the IDs are densely packed in the sense that the ID N will not be used until N-1 has been used. Any ID allocation algorithm that does not maintain this property is incompatible with the implementation in libwayland.
Compositor The compositor is a global object, advertised at connect time. See for the protocol description.
Surfaces A surface manages a rectangular grid of pixels that clients create for displaying their content to the screen. Clients don't know the global position of their surfaces, and cannot access other clients' surfaces. Once the client has finished writing pixels, it 'commits' the buffer; this permits the compositor to access the buffer and read the pixels. When the compositor is finished, it releases the buffer back to the client. See for the protocol description.
Input A seat represents a group of input devices including mice, keyboards and touchscreens. It has a keyboard and pointer focus. Seats are global objects. Pointer events are delivered in surface-local coordinates. The compositor maintains an implicit grab when a button is pressed, to ensure that the corresponding button release event gets delivered to the same surface. But there is no way for clients to take an explicit grab. Instead, surfaces can be mapped as 'popup', which combines transient window semantics with a pointer grab. To avoid race conditions, input events that are likely to trigger further requests (such as button presses, key events, pointer motions) carry serial numbers, and requests such as wl_surface.set_popup require that the serial number of the triggering event is specified. The server maintains a monotonically increasing counter for these serial numbers. Input events also carry timestamps with millisecond granularity. Their base is undefined, so they can't be compared against system time (as obtained with clock_gettime or gettimeofday). They can be compared with each other though, and for instance be used to identify sequences of button presses as double or triple clicks. See for the protocol description. Talk about: keyboard map, change events xkb on Wayland multi pointer Wayland A surface can change the pointer image when the surface is the pointer focus of the input device. Wayland doesn't automatically change the pointer image when a pointer enters a surface, but expects the application to set the cursor it wants in response to the pointer focus and motion events. The rationale is that a client has to manage changing pointer images for UI elements within the surface in response to motion events anyway, so we'll make that the only mechanism for setting or changing the pointer image. If the server receives a request to set the pointer image after the surface loses pointer focus, the request is ignored. To the client this will look like it successfully set the pointer image. The compositor will revert the pointer image back to a default image when no surface has the pointer focus for that device. Clients can revert the pointer image back to the default image by setting a NULL image. What if the pointer moves from one window which has set a special pointer image to a surface that doesn't set an image in response to the motion event? The new surface will be stuck with the special pointer image. We can't just revert the pointer image on leaving a surface, since if we immediately enter a surface that sets a different image, the image will flicker. Broken app, I suppose.
Output An output is a global object, advertised at connect time or as it comes and goes. See for the protocol description. laid out in a big (compositor) coordinate system basically xrandr over Wayland geometry needs position in compositor coordinate system events to advertise available modes, requests to move and change modes
Data sharing between clients The Wayland protocol provides clients a mechanism for sharing data that allows the implementation of copy-paste and drag-and-drop. The client providing the data creates a wl_data_source object and the clients obtaining the data will see it as wl_data_offer object. This interface allows the clients to agree on a mutually supported mime type and transfer the data via a file descriptor that is passed through the protocol. The next section explains the negotiation between data source and data offer objects. explains how these objects are created and passed to different clients using the wl_data_device interface that implements copy-paste and drag-and-drop support. See , , and for protocol descriptions. MIME is defined in RFC's 2045-2049. A registry of MIME types is maintained by the Internet Assigned Numbers Authority (IANA).
Data negotiation A client providing data to other clients will create a wl_data_source object and advertise the mime types for the formats it supports for that data through the wl_data_source.offer request. On the receiving end, the data offer object will generate one wl_data_offer.offer event for each supported mime type. The actual data transfer happens when the receiving client sends a wl_data_offer.receive request. This request takes a mime type and a file descriptor as arguments. This request will generate a wl_data_source.send event on the sending client with the same arguments, and the latter client is expected to write its data to the given file descriptor using the chosen mime type.
Data devices Data devices glue data sources and offers together. A data device is associated with a wl_seat and is obtained by the clients using the wl_data_device_manager factory object, which is also responsible for creating data sources. Clients are informed of new data offers through the wl_data_device.data_offer event. After this event is generated the data offer will advertise the available mime types. New data offers are introduced prior to their use for copy-paste or drag-and-drop.
Selection Each data device has a selection data source. Clients create a data source object using the device manager and may set it as the current selection for a given data device. Whenever the current selection changes, the client with keyboard focus receives a wl_data_device.selection event. This event is also generated on a client immediately before it receives keyboard focus. The data offer is introduced with wl_data_device.data_offer event before the selection event.
Drag and Drop A drag-and-drop operation is started using the wl_data_device.start_drag request. This requests causes a pointer grab that will generate enter, motion and leave events on the data device. A data source is supplied as argument to start_drag, and data offers associated with it are supplied to clients surfaces under the pointer in the wl_data_device.enter event. The data offer is introduced to the client prior to the enter event with the wl_data_device.data_offer event. Clients are expected to provide feedback to the data sending client by calling the wl_data_offer.accept request with a mime type it accepts. If none of the advertised mime types is supported by the receiving client, it should supply NULL to the accept request. The accept request causes the sending client to receive a wl_data_source.target event with the chosen mime type. When the drag ends, the receiving client receives a wl_data_device.drop event at which it is expected to transfer the data using the wl_data_offer.receive request.

Interfaces The protocol includes several interfaces which are used for interacting with the server. Each interface provides requests, events, and errors (which are really just special events) as described above. Specific compositor implementations may have their own interfaces provided as extensions, but there are several which are always expected to be present. Core interfaces:

The server socket must be placed in XDG_RUNTIME_DIR when WAYLAND_DISPLAY (or name, see below) is a simple name, for this function to find it. The server socket is also allowed to exist at an arbitrary path; usage details follow. See below for compatibility issue details. The name argument specifies the name of the socket or NULL to use the default (which is "wayland-0"). The environment variable WAYLAND_DISPLAY replaces the default value. If name is an absolute path, then that path is used as the Wayland socket to which the connection is attempted. Note that in combination with the default-value behavior described above, this implies that setting WAYLAND_DISPLAY to an absolute path will implicitly cause name to take on that absolute path if name is NULL. If WAYLAND_SOCKET is set, this function behaves like wl_display_connect_to_fd with the file-descriptor number taken from the environment variable. Support for interpreting WAYLAND_DISPLAY as an absolute path is a change in behavior compared to wl_display_connect's behavior in versions 1.14 and older of Wayland. It is no longer guaranteed in versions 1.15 and higher that the Wayland socket chosen is equivalent to manually constructing a socket pathname by concatenating XDG_RUNTIME_DIR and WAYLAND_DISPLAY. Manual construction of the socket path must account for the possibility that WAYLAND_DISPLAY contains an absolute path. wl_display_connect_to_fd connects to a Wayland socket with an explicit file-descriptor. The file-descriptor is passed as argument fd. Return Value wl_display_connect and wl_display_connect_to_fd return a new display context object or NULL on failure. errno is set correspondingly.

The server socket must be placed in \fBXDG_RUNTIME_DIR\fR when \fBWAYLAND_DISPLAY\fR (or \fIname\fR, see below) is a simple name, for this function to find it\&. The server socket is also allowed to exist at an arbitrary path; usage details follow\&. See below for compatibility issue details\&. .PP The \fIname\fR argument specifies the name of the socket or \fBNULL\fR to use the default (which is \fB"wayland\-0"\fR)\&. The environment variable \fBWAYLAND_DISPLAY\fR replaces the default value\&. If \fIname\fR is an absolute path, then that path is used as the Wayland socket to which the connection is attempted\&. Note that in combination with the default\-value behavior described above, this implies that setting \fBWAYLAND_DISPLAY\fR to an absolute path will implicitly cause \fIname\fR to take on that absolute path if \fIname\fR is \fBNULL\fR\&. If \fBWAYLAND_SOCKET\fR is set, this function behaves like \fBwl_display_connect_to_fd\fR with the file\-descriptor number taken from the environment variable\&. .PP Support for interpreting \fBWAYLAND_DISPLAY\fR as an absolute path is a change in behavior compared to \fBwl_display_connect\fR\*(Aqs behavior in versions 1\&.14 and older of Wayland\&. It is no longer guaranteed in versions 1\&.15 and higher that the Wayland socket chosen is equivalent to manually constructing a socket pathname by concatenating \fBXDG_RUNTIME_DIR\fR and \fBWAYLAND_DISPLAY\fR\&. Manual construction of the socket path must account for the possibility that \fBWAYLAND_DISPLAY\fR contains an absolute path\&. .PP \fBwl_display_connect_to_fd\fR connects to a Wayland socket with an explicit file\-descriptor\&. The file\-descriptor is passed as argument \fIfd\fR\&. .SH "RETURN VALUE" .PP \fBwl_display_connect\fR and \fBwl_display_connect_to_fd\fR return a new display context object or NULL on failure\&. \fIerrno\fR is set correspondingly\&. .SH "SEE ALSO" .PP \fBwayland-client\fR(7), \fBwl_display_disconnect\fR(3), \fBwl_display_iterate\fR(3) wayland-1.18.0/doc/Makefile.am0000644000175000017500000000003713620636273015107 0ustar zumbizumbiSUBDIRS = doxygen publican man wayland-1.18.0/doc/meson.build0000644000175000017500000000221013620636273015210 0ustar zumbizumbidot = find_program('dot') doxygen = find_program('doxygen') xsltproc = find_program('xsltproc') xmlto = find_program('xmlto') cmd = run_command(doxygen, '--version', check: true) message('doxygen: ' + cmd.stdout().strip()) vers = cmd.stdout().strip() if vers.version_compare('< 1.6.0') error('Doxygen 1.6 or later is required for building documentation, found @0@.'.format(vers)) endif cmd = run_command(dot, '-V', check: true) message('dot: ' + cmd.stderr().strip()) vers = cmd.stderr().split('version')[1].strip().split(' ')[0] if vers.version_compare('< 2.26.0') error('Dot (Graphviz) 2.26 or later is required for building documentation, found @0@.'.format(vers)) endif manpage_xsl = 'http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl' cmd = run_command(xsltproc, '--nonet', manpage_xsl) if cmd.returncode() != 0 error('The style sheet for man pages providing "@0@" was not found.'.format(manpage_xsl)) endif publican_install_prefix = join_paths( get_option('prefix'), get_option('datadir'), 'doc', meson.project_name(), 'Wayland', 'en-US' ) publican_html_dir = 'html' subdir('doxygen') subdir('man') subdir('publican') wayland-1.18.0/doc/Makefile.in0000644000175000017500000004542413620636304015124 0ustar zumbizumbi# Makefile.in generated by automake 1.16.1 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2018 Free Software Foundation, Inc. # This Makefile.in is free software;

The core global object. This is a special singleton object. It is used for internal Wayland protocol features. The sync request asks the server to emit the 'done' event on the returned wl_callback object. Since requests are handled in-order and events are delivered in-order, this can be used as a barrier to ensure all previous requests and the resulting events have been handled. The object returned by this request will be destroyed by the compositor after the callback is fired and as such the client must not attempt to use it after that point. The callback_data passed in the callback is the event serial. This request creates a registry object that allows the client to list and bind the global objects available from the compositor. It should be noted that the server side resources consumed in response to a get_registry request can only be released when the client disconnects, not when the client side proxy is destroyed. Therefore, clients should invoke get_registry as infrequently as possible to avoid wasting memory. The error event is sent out when a fatal (non-recoverable) error has occurred. The object_id argument is the object where the error occurred, most often in response to a request to that object. The code identifies the error and is defined by the object interface. As such, each interface defines its own set of error codes. The message is a brief description of the error, for (debugging) convenience. These errors are global and can be emitted in response to any server request. This event is used internally by the object ID management logic. When a client deletes an object that it had created, the server will send this event to acknowledge that it has seen the delete request. When the client receives this event, it will know that it can safely reuse the object ID. The singleton global registry object. The server has a number of global objects that are available to all clients. These objects typically represent an actual object in the server (for example, an input device) or they are singleton objects that provide extension functionality. When a client creates a registry object, the registry object will emit a global event for each global currently in the registry. Globals come and go as a result of device or monitor hotplugs, reconfiguration or other events, and the registry will send out global and global_remove events to keep the client up to date with the changes. To mark the end of the initial burst of events, the client can use the wl_display.sync request immediately after calling wl_display.get_registry. A client can bind to a global object by using the bind request. This creates a client-side handle that lets the object emit events to the client and lets the client invoke requests on the object. Binds a new, client-created object to the server using the specified name as the identifier. Notify the client of global objects. The event notifies the client that a global object with the given name is now available, and it implements the given version of the given interface. Notify the client of removed global objects. This event notifies the client that the global identified by name is no longer available. If the client bound to the global using the bind request, the client should now destroy that object. The object remains valid and requests to the object will be ignored until the client destroys it, to avoid races between the global going away and a client sending a request to it. Clients can handle the 'done' event to get notified when the related request is done. Notify the client when the related request is done. A compositor. This object is a singleton global. The compositor is in charge of combining the contents of multiple surfaces into one displayable output. Ask the compositor to create a new surface. Ask the compositor to create a new region. The wl_shm_pool object encapsulates a piece of memory shared between the compositor and client. Through the wl_shm_pool object, the client can allocate shared memory wl_buffer objects. All objects created through the same pool share the same underlying mapped memory. Reusing the mapped memory avoids the setup/teardown overhead and is useful when interactively resizing a surface or for many small buffers. Create a wl_buffer object from the pool. The buffer is created offset bytes into the pool and has width and height as specified. The stride argument specifies the number of bytes from the beginning of one row to the beginning of the next. The format is the pixel format of the buffer and must be one of those advertised through the wl_shm.format event. A buffer will keep a reference to the pool it was created from so it is valid to destroy the pool immediately after creating a buffer from it. Destroy the shared memory pool. The mmapped memory will be released when all buffers that have been created from this pool are gone. This request will cause the server to remap the backing memory for the pool from the file descriptor passed when the pool was created, but using the new size. This request can only be used to make the pool bigger. A singleton global object that provides support for shared memory. Clients can create wl_shm_pool objects using the create_pool request. At connection setup time, the wl_shm object emits one or more format events to inform clients about the valid pixel formats that can be used for buffers. These errors can be emitted in response to wl_shm requests. This describes the memory layout of an individual pixel. All renderers should support argb8888 and xrgb8888 but any other formats are optional and may not be supported by the particular renderer in use. The drm format codes match the macros defined in drm_fourcc.h, except argb8888 and xrgb8888. The formats actually supported by the compositor will be reported by the format event. Create a new wl_shm_pool object. The pool can be used to create shared memory based buffer objects. The server will mmap size bytes of the passed file descriptor, to use as backing memory for the pool. Informs the client about a valid pixel format that can be used for buffers. Known formats include argb8888 and xrgb8888. A buffer provides the content for a wl_surface. Buffers are created through factory interfaces such as wl_drm, wl_shm or similar. It has a width and a height and can be attached to a wl_surface, but the mechanism by which a client provides and updates the contents is defined by the buffer factory interface. Destroy a buffer. If and how you need to release the backing storage is defined by the buffer factory interface. For possible side-effects to a surface, see wl_surface.attach. Sent when this wl_buffer is no longer used by the compositor. The client is now free to reuse or destroy this buffer and its backing storage. If a client receives a release event before the frame callback requested in the same wl_surface.commit that attaches this wl_buffer to a surface, then the client is immediately free to reuse the buffer and its backing storage, and does not need a second buffer for the next surface content update. Typically this is possible, when the compositor maintains a copy of the wl_surface contents, e.g. as a GL texture. This is an important optimization for GL(ES) compositors with wl_shm clients. A wl_data_offer represents a piece of data offered for transfer by another client (the source client). It is used by the copy-and-paste and drag-and-drop mechanisms. The offer describes the different mime types that the data can be converted to and provides the mechanism for transferring the data directly from the source client. Indicate that the client can accept the given mime type, or NULL for not accepted. For objects of version 2 or older, this request is used by the client to give feedback whether the client can receive the given mime type, or NULL if none is accepted; the feedback does not determine whether the drag-and-drop operation succeeds or not. For objects of version 3 or newer, this request determines the final result of the drag-and-drop operation. If the end result is that no mime types were accepted, the drag-and-drop operation will be cancelled and the corresponding drag source will receive wl_data_source.cancelled. Clients may still use this event in conjunction with wl_data_source.action for feedback. To transfer the offered data, the client issues this request and indicates the mime type it wants to receive. The transfer happens through the passed file descriptor (typically created with the pipe system call). The source client writes the data in the mime type representation requested and then closes the file descriptor. The receiving client reads from the read end of the pipe until EOF and then closes its end, at which point the transfer is complete. This request may happen multiple times for different mime types, both before and after wl_data_device.drop. Drag-and-drop destination clients may preemptively fetch data or examine it more closely to determine acceptance. Destroy the data offer. Sent immediately after creating the wl_data_offer object. One event per offered mime type. Notifies the compositor that the drag destination successfully finished the drag-and-drop operation. Upon receiving this request, the compositor will emit wl_data_source.dnd_finished on the drag source client. It is a client error to perform other requests than wl_data_offer.destroy after this one. It is also an error to perform this request after a NULL mime type has been set in wl_data_offer.accept or no action was received through wl_data_offer.action. If wl_data_offer.finish request is received for a non drag and drop operation, the invalid_finish protocol error is raised. Sets the actions that the destination side client supports for this operation. This request may trigger the emission of wl_data_source.action and wl_data_offer.action events if the compositor needs to change the selected action. This request can be called multiple times throughout the drag-and-drop operation, typically in response to wl_data_device.enter or wl_data_device.motion events. This request determines the final result of the drag-and-drop operation. If the end result is that no action is accepted, the drag source will receive wl_data_source.cancelled. The dnd_actions argument must contain only values expressed in the wl_data_device_manager.dnd_actions enum, and the preferred_action argument must only contain one of those values set, otherwise it will result in a protocol error. While managing an "ask" action, the destination drag-and-drop client may perform further wl_data_offer.receive requests, and is expected to perform one last wl_data_offer.set_actions request with a preferred action other than "ask" (and optionally wl_data_offer.accept) before requesting wl_data_offer.finish, in order to convey the action selected by the user. If the preferred action is not in the wl_data_offer.source_actions mask, an error will be raised. If the "ask" action is dismissed (e.g. user cancellation), the client is expected to perform wl_data_offer.destroy right away. This request can only be made on drag-and-drop offers, a protocol error will be raised otherwise. This event indicates the actions offered by the data source. It will be sent right after wl_data_device.enter, or anytime the source side changes its offered actions through wl_data_source.set_actions. This event indicates the action selected by the compositor after matching the source/destination side actions. Only one action (or none) will be offered here. This event can be emitted multiple times during the drag-and-drop operation in response to destination side action changes through wl_data_offer.set_actions. This event will no longer be emitted after wl_data_device.drop happened on the drag-and-drop destination, the client must honor the last action received, or the last preferred one set through wl_data_offer.set_actions when handling an "ask" action. Compositors may also change the selected action on the fly, mainly in response to keyboard modifier changes during the drag-and-drop operation. The most recent action received is always the valid one. Prior to receiving wl_data_device.drop, the chosen action may change (e.g. due to keyboard modifiers being pressed). At the time of receiving wl_data_device.drop the drag-and-drop destination must honor the last action received. Action changes may still happen after wl_data_device.drop, especially on "ask" actions, where the drag-and-drop destination may choose another action afterwards. Action changes happening at this stage are always the result of inter-client negotiation, the compositor shall no longer be able to induce a different action. Upon "ask" actions, it is expected that the drag-and-drop destination may potentially choose a different action and/or mime type, based on wl_data_offer.source_actions and finally chosen by the user (e.g. popping up a menu with the available options). The final wl_data_offer.set_actions and wl_data_offer.accept requests must happen before the call to wl_data_offer.finish. The wl_data_source object is the source side of a wl_data_offer. It is created by the source client in a data transfer and provides a way to describe the offered data and a way to respond to requests to transfer the data. This request adds a mime type to the set of mime types advertised to targets. Can be called several times to offer multiple types. Destroy the data source. Sent when a target accepts pointer_focus or motion events. If a target does not accept any of the offered types, type is NULL. Used for feedback during drag-and-drop. Request for data from the client. Send the data as the specified mime type over the passed file descriptor, then close it. This data source is no longer valid. There are several reasons why this could happen: - The data source has been replaced by another data source. - The drag-and-drop operation was performed, but the drop destination did not accept any of the mime types offered through wl_data_source.target. - The drag-and-drop operation was performed, but the drop destination did not select any of the actions present in the mask offered through wl_data_source.action. - The drag-and-drop operation was performed but didn't happen over a surface. - The compositor cancelled the drag-and-drop operation (e.g. compositor dependent timeouts to avoid stale drag-and-drop transfers). The client should clean up and destroy this data source. For objects of version 2 or older, wl_data_source.cancelled will only be emitted if the data source was replaced by another data source. Sets the actions that the source side client supports for this operation. This request may trigger wl_data_source.action and wl_data_offer.action events if the compositor needs to change the selected action. The dnd_actions argument must contain only values expressed in the wl_data_device_manager.dnd_actions enum, otherwise it will result in a protocol error. This request must be made once only, and can only be made on sources used in drag-and-drop, so it must be performed before wl_data_device.start_drag. Attempting to use the source other than for drag-and-drop will raise a protocol error. The user performed the drop action. This event does not indicate acceptance, wl_data_source.cancelled may still be emitted afterwards if the drop destination does not accept any mime type. However, this event might however not be received if the compositor cancelled the drag-and-drop operation before this event could happen. Note that the data_source may still be used in the future and should not be destroyed here. The drop destination finished interoperating with this data source, so the client is now free to destroy this data source and free all associated data. If the action used to perform the operation was "move", the source can now delete the transferred data. This event indicates the action selected by the compositor after matching the source/destination side actions. Only one action (or none) will be offered here. This event can be emitted multiple times during the drag-and-drop operation, mainly in response to destination side changes through wl_data_offer.set_actions, and as the data device enters/leaves surfaces. It is only possible to receive this event after wl_data_source.dnd_drop_performed if the drag-and-drop operation ended in an "ask" action, in which case the final wl_data_source.action event will happen immediately before wl_data_source.dnd_finished. Compositors may also change the selected action on the fly, mainly in response to keyboard modifier changes during the drag-and-drop operation. The most recent action received is always the valid one. The chosen action may change alongside negotiation (e.g. an "ask" action can turn into a "move" operation), so the effects of the final action must always be applied in wl_data_offer.dnd_finished. Clients can trigger cursor surface changes from this point, so they reflect the current action. There is one wl_data_device per seat which can be obtained from the global wl_data_device_manager singleton. A wl_data_device provides access to inter-client data transfer mechanisms such as copy-and-paste and drag-and-drop. This request asks the compositor to start a drag-and-drop operation on behalf of the client. The source argument is the data source that provides the data for the eventual data transfer. If source is NULL, enter, leave and motion events are sent only to the client that initiated the drag and the client is expected to handle the data passing internally. The origin surface is the surface where the drag originates and the client must have an active implicit grab that matches the serial. The icon surface is an optional (can be NULL) surface that provides an icon to be moved around with the cursor. Initially, the top-left corner of the icon surface is placed at the cursor hotspot, but subsequent wl_surface.attach request can move the relative position. Attach requests must be confirmed with wl_surface.commit as usual. The icon surface is given the role of a drag-and-drop icon. If the icon surface already has another role, it raises a protocol error. The current and pending input regions of the icon wl_surface are cleared, and wl_surface.set_input_region is ignored until the wl_surface is no longer used as the icon surface. When the use as an icon ends, the current and pending input regions become undefined, and the wl_surface is unmapped. This request asks the compositor to set the selection to the data from the source on behalf of the client. To unset the selection, set the source to NULL. The data_offer event introduces a new wl_data_offer object, which will subsequently be used in either the data_device.enter event (for drag-and-drop) or the data_device.selection event (for selections). Immediately following the data_device_data_offer event, the new data_offer object will send out data_offer.offer events to describe the mime types it offers. This event is sent when an active drag-and-drop pointer enters a surface owned by the client. The position of the pointer at enter time is provided by the x and y arguments, in surface-local coordinates. This event is sent when the drag-and-drop pointer leaves the surface and the session ends. The client must destroy the wl_data_offer introduced at enter time at this point. This event is sent when the drag-and-drop pointer moves within the currently focused surface. The new position of the pointer is provided by the x and y arguments, in surface-local coordinates. The event is sent when a drag-and-drop operation is ended because the implicit grab is removed. The drag-and-drop destination is expected to honor the last action received through wl_data_offer.action, if the resulting action is "copy" or "move", the destination can still perform wl_data_offer.receive requests, and is expected to end all transfers with a wl_data_offer.finish request. If the resulting action is "ask", the action will not be considered final. The drag-and-drop destination is expected to perform one last wl_data_offer.set_actions request, or wl_data_offer.destroy in order to cancel the operation. The selection event is sent out to notify the client of a new wl_data_offer for the selection for this device. The data_device.data_offer and the data_offer.offer events are sent out immediately before this event to introduce the data offer object. The selection event is sent to a client immediately before receiving keyboard focus and when a new selection is set while the client has keyboard focus. The data_offer is valid until a new data_offer or NULL is received or until the client loses keyboard focus. The client must destroy the previous selection data_offer, if any, upon receiving this event. This request destroys the data device. The wl_data_device_manager is a singleton global object that provides access to inter-client data transfer mechanisms such as copy-and-paste and drag-and-drop. These mechanisms are tied to a wl_seat and this interface lets a client get a wl_data_device corresponding to a wl_seat. Depending on the version bound, the objects created from the bound wl_data_device_manager object will have different requirements for functioning properly. See wl_data_source.set_actions, wl_data_offer.accept and wl_data_offer.finish for details. Create a new data source. Create a new data device for a given seat. This is a bitmask of the available/preferred actions in a drag-and-drop operation. In the compositor, the selected action is a result of matching the actions offered by the source and destination sides. "action" events with a "none" action will be sent to both source and destination if there is no match. All further checks will effectively happen on (source actions ∩ destination actions). In addition, compositors may also pick different actions in reaction to key modifiers being pressed. One common design that is used in major toolkits (and the behavior recommended for compositors) is: - If no modifiers are pressed, the first match (in bit order) will be used. - Pressing Shift selects "move", if enabled in the mask. - Pressing Control selects "copy", if enabled in the mask. Behavior beyond that is considered implementation-dependent. Compositors may for example bind other modifiers (like Alt/Meta) or drags initiated with other buttons than BTN_LEFT to specific actions (e.g. "ask"). This interface is implemented by servers that provide desktop-style user interfaces. It allows clients to associate a wl_shell_surface with a basic surface. Note! This protocol is deprecated and not intended for production use. For desktop-style user interfaces, use xdg_shell. Create a shell surface for an existing surface. This gives the wl_surface the role of a shell surface. If the wl_surface already has another role, it raises a protocol error. Only one shell surface can be associated with a given surface. An interface that may be implemented by a wl_surface, for implementations that provide a desktop-style user interface. It provides requests to treat surfaces like toplevel, fullscreen or popup windows, move, resize or maximize them, associate metadata like title and class, etc. On the server side the object is automatically destroyed when the related wl_surface is destroyed. On the client side, wl_shell_surface_destroy() must be called before destroying the wl_surface object. A client must respond to a ping event with a pong request or the client may be deemed unresponsive. Start a pointer-driven move of the surface. This request must be used in response to a button press event. The server may ignore move requests depending on the state of the surface (e.g. fullscreen or maximized). These values are used to indicate which edge of a surface is being dragged in a resize operation. The server may use this information to adapt its behavior, e.g. choose an appropriate cursor image. Start a pointer-driven resizing of the surface. This request must be used in response to a button press event. The server may ignore resize requests depending on the state of the surface (e.g. fullscreen or maximized). Map the surface as a toplevel surface. A toplevel surface is not fullscreen, maximized or transient. These flags specify details of the expected behaviour of transient surfaces. Used in the set_transient request. Map the surface relative to an existing surface. The x and y arguments specify the location of the upper left corner of the surface relative to the upper left corner of the parent surface, in surface-local coordinates. The flags argument controls details of the transient behaviour. Hints to indicate to the compositor how to deal with a conflict between the dimensions of the surface and the dimensions of the output. The compositor is free to ignore this parameter. Map the surface as a fullscreen surface. If an output parameter is given then the surface will be made fullscreen on that output. If the client does not specify the output then the compositor will apply its policy - usually choosing the output on which the surface has the biggest surface area. The client may specify a method to resolve a size conflict between the output size and the surface size - this is provided through the method parameter. The framerate parameter is used only when the method is set to "driver", to indicate the preferred framerate. A value of 0 indicates that the client does not care about framerate. The framerate is specified in mHz, that is framerate of 60000 is 60Hz. A method of "scale" or "driver" implies a scaling operation of the surface, either via a direct scaling operation or a change of the output mode. This will override any kind of output scaling, so that mapping a surface with a buffer size equal to the mode can fill the screen independent of buffer_scale. A method of "fill" means we don't scale up the buffer, however any output scale is applied. This means that you may run into an edge case where the application maps a buffer with the same size of the output mode but buffer_scale 1 (thus making a surface larger than the output). In this case it is allowed to downscale the results to fit the screen. The compositor must reply to this request with a configure event with the dimensions for the output on which the surface will be made fullscreen. Map the surface as a popup. A popup surface is a transient surface with an added pointer grab. An existing implicit grab will be changed to owner-events mode, and the popup grab will continue after the implicit grab ends (i.e. releasing the mouse button does not cause the popup to be unmapped). The popup grab continues until the window is destroyed or a mouse button is pressed in any other client's window. A click in any of the client's surfaces is reported as normal, however, clicks in other clients' surfaces will be discarded and trigger the callback. The x and y arguments specify the location of the upper left corner of the surface relative to the upper left corner of the parent surface, in surface-local coordinates. Map the surface as a maximized surface. If an output parameter is given then the surface will be maximized on that output. If the client does not specify the output then the compositor will apply its policy - usually choosing the output on which the surface has the biggest surface area. The compositor will reply with a configure event telling the expected new surface size. The operation is completed on the next buffer attach to this surface. A maximized surface typically fills the entire output it is bound to, except for desktop elements such as panels. This is the main difference between a maximized shell surface and a fullscreen shell surface. The details depend on the compositor implementation. Set a short title for the surface. This string may be used to identify the surface in a task bar, window list, or other user interface elements provided by the compositor. The string must be encoded in UTF-8. Set a class for the surface. The surface class identifies the general class of applications to which the surface belongs. A common convention is to use the file name (or the full path if it is a non-standard location) of the application's .desktop file as the class. Ping a client to check if it is receiving events and sending requests. A client is expected to reply with a pong request. The configure event asks the client to resize its surface. The size is a hint, in the sense that the client is free to ignore it if it doesn't resize, pick a smaller size (to satisfy aspect ratio or resize in steps of NxM pixels). The edges parameter provides a hint about how the surface was resized. The client may use this information to decide how to adjust its content to the new size (e.g. a scrolling area might adjust its content position to leave the viewable content unmoved). The client is free to dismiss all but the last configure event it received. The width and height arguments specify the size of the window in surface-local coordinates. The popup_done event is sent out when a popup grab is broken, that is, when the user clicks a surface that doesn't belong to the client owning the popup surface. A surface is a rectangular area that may be displayed on zero or more outputs, and shown any number of times at the compositor's discretion. They can present wl_buffers, receive user input, and define a local coordinate system. The size of a surface (and relative positions on it) is described in surface-local coordinates, which may differ from the buffer coordinates of the pixel content, in case a buffer_transform or a buffer_scale is used. A surface without a "role" is fairly useless: a compositor does not know where, when or how to present it. The role is the purpose of a wl_surface. Examples of roles are a cursor for a pointer (as set by wl_pointer.set_cursor), a drag icon (wl_data_device.start_drag), a sub-surface (wl_subcompositor.get_subsurface), and a window as defined by a shell protocol (e.g. wl_shell.get_shell_surface). A surface can have only one role at a time. Initially a wl_surface does not have a role. Once a wl_surface is given a role, it is set permanently for the whole lifetime of the wl_surface object. Giving the current role again is allowed, unless explicitly forbidden by the relevant interface specification. Surface roles are given by requests in other interfaces such as wl_pointer.set_cursor. The request should explicitly mention that this request gives a role to a wl_surface. Often, this request also creates a new protocol object that represents the role and adds additional functionality to wl_surface. When a client wants to destroy a wl_surface, they must destroy this 'role object' before the wl_surface. Destroying the role object does not remove the role from the wl_surface, but it may stop the wl_surface from "playing the role". For instance, if a wl_subsurface object is destroyed, the wl_surface it was created for will be unmapped and forget its position and z-order. It is allowed to create a wl_subsurface for the same wl_surface again, but it is not allowed to use the wl_surface as a cursor (cursor is a different role than sub-surface, and role switching is not allowed). These errors can be emitted in response to wl_surface requests. Deletes the surface and invalidates its object ID. Set a buffer as the content of this surface. The new size of the surface is calculated based on the buffer size transformed by the inverse buffer_transform and the inverse buffer_scale. This means that the supplied buffer must be an integer multiple of the buffer_scale. The x and y arguments specify the location of the new pending buffer's upper left corner, relative to the current buffer's upper left corner, in surface-local coordinates. In other words, the x and y, combined with the new surface size define in which directions the surface's size changes. Surface contents are double-buffered state, see wl_surface.commit. The initial surface contents are void; there is no content. wl_surface.attach assigns the given wl_buffer as the pending wl_buffer. wl_surface.commit makes the pending wl_buffer the new surface contents, and the size of the surface becomes the size calculated from the wl_buffer, as described above. After commit, there is no pending buffer until the next attach. Committing a pending wl_buffer allows the compositor to read the pixels in the wl_buffer. The compositor may access the pixels at any time after the wl_surface.commit request. When the compositor will not access the pixels anymore, it will send the wl_buffer.release event. Only after receiving wl_buffer.release, the client may reuse the wl_buffer. A wl_buffer that has been attached and then replaced by another attach instead of committed will not receive a release event, and is not used by the compositor. If a pending wl_buffer has been committed to more than one wl_surface, the delivery of wl_buffer.release events becomes undefined. A well behaved client should not rely on wl_buffer.release events in this case. Alternatively, a client could create multiple wl_buffer objects from the same backing storage or use wp_linux_buffer_release. Destroying the wl_buffer after wl_buffer.release does not change the surface contents. However, if the client destroys the wl_buffer before receiving the wl_buffer.release event, the surface contents become undefined immediately. If wl_surface.attach is sent with a NULL wl_buffer, the following wl_surface.commit will remove the surface content. This request is used to describe the regions where the pending buffer is different from the current surface contents, and where the surface therefore needs to be repainted. The compositor ignores the parts of the damage that fall outside of the surface. Damage is double-buffered state, see wl_surface.commit. The damage rectangle is specified in surface-local coordinates, where x and y specify the upper left corner of the damage rectangle. The initial value for pending damage is empty: no damage. wl_surface.damage adds pending damage: the new pending damage is the union of old pending damage and the given rectangle. wl_surface.commit assigns pending damage as the current damage, and clears pending damage. The server will clear the current damage as it repaints the surface. Note! New clients should not use this request. Instead damage can be posted with wl_surface.damage_buffer which uses buffer coordinates instead of surface coordinates. Request a notification when it is a good time to start drawing a new frame, by creating a frame callback. This is useful for throttling redrawing operations, and driving animations. When a client is animating on a wl_surface, it can use the 'frame' request to get notified when it is a good time to draw and commit the next frame of animation. If the client commits an update earlier than that, it is likely that some updates will not make it to the display, and the client is wasting resources by drawing too often. The frame request will take effect on the next wl_surface.commit. The notification will only be posted for one frame unless requested again. For a wl_surface, the notifications are posted in the order the frame requests were committed. The server must send the notifications so that a client will not send excessive updates, while still allowing the highest possible update rate for clients that wait for the reply before drawing again. The server should give some time for the client to draw and commit after sending the frame callback events to let it hit the next output refresh. A server should avoid signaling the frame callbacks if the surface is not visible in any way, e.g. the surface is off-screen, or completely obscured by other opaque surfaces. The object returned by this request will be destroyed by the compositor after the callback is fired and as such the client must not attempt to use it after that point. The callback_data passed in the callback is the current time, in milliseconds, with an undefined base. This request sets the region of the surface that contains opaque content. The opaque region is an optimization hint for the compositor that lets it optimize the redrawing of content behind opaque regions. Setting an opaque region is not required for correct behaviour, but marking transparent content as opaque will result in repaint artifacts. The opaque region is specified in surface-local coordinates. The compositor ignores the parts of the opaque region that fall outside of the surface. Opaque region is double-buffered state, see wl_surface.commit. wl_surface.set_opaque_region changes the pending opaque region. wl_surface.commit copies the pending region to the current region. Otherwise, the pending and current regions are never changed. The initial value for an opaque region is empty. Setting the pending opaque region has copy semantics, and the wl_region object can be destroyed immediately. A NULL wl_region causes the pending opaque region to be set to empty. This request sets the region of the surface that can receive pointer and touch events. Input events happening outside of this region will try the next surface in the server surface stack. The compositor ignores the parts of the input region that fall outside of the surface. The input region is specified in surface-local coordinates. Input region is double-buffered state, see wl_surface.commit. wl_surface.set_input_region changes the pending input region. wl_surface.commit copies the pending region to the current region. Otherwise the pending and current regions are never changed, except cursor and icon surfaces are special cases, see wl_pointer.set_cursor and wl_data_device.start_drag. The initial value for an input region is infinite. That means the whole surface will accept input. Setting the pending input region has copy semantics, and the wl_region object can be destroyed immediately. A NULL wl_region causes the input region to be set to infinite. Surface state (input, opaque, and damage regions, attached buffers, etc.) is double-buffered. Protocol requests modify the pending state, as opposed to the current state in use by the compositor. A commit request atomically applies all pending state, replacing the current state. After commit, the new pending state is as documented for each related request. On commit, a pending wl_buffer is applied first, and all other state second. This means that all coordinates in double-buffered state are relative to the new wl_buffer coming into use, except for wl_surface.attach itself. If there is no pending wl_buffer, the coordinates are relative to the current surface contents. All requests that need a commit to become effective are documented to affect double-buffered state. Other interfaces may add further double-buffered surface state. This is emitted whenever a surface's creation, movement, or resizing results in some part of it being within the scanout region of an output. Note that a surface may be overlapping with zero or more outputs. This is emitted whenever a surface's creation, movement, or resizing results in it no longer having any part of it within the scanout region of an output. This request sets an optional transformation on how the compositor interprets the contents of the buffer attached to the surface. The accepted values for the transform parameter are the values for wl_output.transform. Buffer transform is double-buffered state, see wl_surface.commit. A newly created surface has its buffer transformation set to normal. wl_surface.set_buffer_transform changes the pending buffer transformation. wl_surface.commit copies the pending buffer transformation to the current one. Otherwise, the pending and current values are never changed. The purpose of this request is to allow clients to render content according to the output transform, thus permitting the compositor to use certain optimizations even if the display is rotated. Using hardware overlays and scanning out a client buffer for fullscreen surfaces are examples of such optimizations. Those optimizations are highly dependent on the compositor implementation, so the use of this request should be considered on a case-by-case basis. Note that if the transform value includes 90 or 270 degree rotation, the width of the buffer will become the surface height and the height of the buffer will become the surface width. If transform is not one of the values from the wl_output.transform enum the invalid_transform protocol error is raised. This request sets an optional scaling factor on how the compositor interprets the contents of the buffer attached to the window. Buffer scale is double-buffered state, see wl_surface.commit. A newly created surface has its buffer scale set to 1. wl_surface.set_buffer_scale changes the pending buffer scale. wl_surface.commit copies the pending buffer scale to the current one. Otherwise, the pending and current values are never changed. The purpose of this request is to allow clients to supply higher resolution buffer data for use on high resolution outputs. It is intended that you pick the same buffer scale as the scale of the output that the surface is displayed on. This means the compositor can avoid scaling when rendering the surface on that output. Note that if the scale is larger than 1, then you have to attach a buffer that is larger (by a factor of scale in each dimension) than the desired surface size. If scale is not positive the invalid_scale protocol error is raised. This request is used to describe the regions where the pending buffer is different from the current surface contents, and where the surface therefore needs to be repainted. The compositor ignores the parts of the damage that fall outside of the surface. Damage is double-buffered state, see wl_surface.commit. The damage rectangle is specified in buffer coordinates, where x and y specify the upper left corner of the damage rectangle. The initial value for pending damage is empty: no damage. wl_surface.damage_buffer adds pending damage: the new pending damage is the union of old pending damage and the given rectangle. wl_surface.commit assigns pending damage as the current damage, and clears pending damage. The server will clear the current damage as it repaints the surface. This request differs from wl_surface.damage in only one way - it takes damage in buffer coordinates instead of surface-local coordinates. While this generally is more intuitive than surface coordinates, it is especially desirable when using wp_viewport or when a drawing library (like EGL) is unaware of buffer scale and buffer transform. Note: Because buffer transformation changes and damage requests may be interleaved in the protocol stream, it is impossible to determine the actual mapping between surface and buffer damage until wl_surface.commit time. Therefore, compositors wishing to take both kinds of damage into account will have to accumulate damage from the two requests separately and only transform from one to the other after receiving the wl_surface.commit. A seat is a group of keyboards, pointer and touch devices. This object is published as a global during start up, or when such a device is hot plugged. A seat typically has a pointer and maintains a keyboard focus and a pointer focus. This is a bitmask of capabilities this seat has; if a member is set, then it is present on the seat. This is emitted whenever a seat gains or loses the pointer, keyboard or touch capabilities. The argument is a capability enum containing the complete set of capabilities this seat has. When the pointer capability is added, a client may create a wl_pointer object using the wl_seat.get_pointer request. This object will receive pointer events until the capability is removed in the future. When the pointer capability is removed, a client should destroy the wl_pointer objects associated with the seat where the capability was removed, using the wl_pointer.release request. No further pointer events will be received on these objects. In some compositors, if a seat regains the pointer capability and a client has a previously obtained wl_pointer object of version 4 or less, that object may start sending pointer events again. This behavior is considered a misinterpretation of the intended behavior and must not be relied upon by the client. wl_pointer objects of version 5 or later must not send events if created before the most recent event notifying the client of an added pointer capability. The above behavior also applies to wl_keyboard and wl_touch with the keyboard and touch capabilities, respectively. The ID provided will be initialized to the wl_pointer interface for this seat. This request only takes effect if the seat has the pointer capability, or has had the pointer capability in the past. It is a protocol violation to issue this request on a seat that has never had the pointer capability. The ID provided will be initialized to the wl_keyboard interface for this seat. This request only takes effect if the seat has the keyboard capability, or has had the keyboard capability in the past. It is a protocol violation to issue this request on a seat that has never had the keyboard capability. The ID provided will be initialized to the wl_touch interface for this seat. This request only takes effect if the seat has the touch capability, or has had the touch capability in the past. It is a protocol violation to issue this request on a seat that has never had the touch capability. In a multiseat configuration this can be used by the client to help identify which physical devices the seat represents. Based on the seat configuration used by the compositor. Using this request a client can tell the server that it is not going to use the seat object anymore. The wl_pointer interface represents one or more input devices, such as mice, which control the pointer location and pointer_focus of a seat. The wl_pointer interface generates motion, enter and leave events for the surfaces that the pointer is located over, and button and axis events for button presses, button releases and scrolling. Set the pointer surface, i.e., the surface that contains the pointer image (cursor). This request gives the surface the role of a cursor. If the surface already has another role, it raises a protocol error. The cursor actually changes only if the pointer focus for this device is one of the requesting client's surfaces or the surface parameter is the current pointer surface. If there was a previous surface set with this request it is replaced. If surface is NULL, the pointer image is hidden. The parameters hotspot_x and hotspot_y define the position of the pointer surface relative to the pointer location. Its top-left corner is always at (x, y) - (hotspot_x, hotspot_y), where (x, y) are the coordinates of the pointer location, in surface-local coordinates. On surface.attach requests to the pointer surface, hotspot_x and hotspot_y are decremented by the x and y parameters passed to the request. Attach must be confirmed by wl_surface.commit as usual. The hotspot can also be updated by passing the currently set pointer surface to this request with new values for hotspot_x and hotspot_y. The current and pending input regions of the wl_surface are cleared, and wl_surface.set_input_region is ignored until the wl_surface is no longer used as the cursor. When the use as a cursor ends, the current and pending input regions become undefined, and the wl_surface is unmapped. Notification that this seat's pointer is focused on a certain surface. When a seat's focus enters a surface, the pointer image is undefined and a client should respond to this event by setting an appropriate pointer image with the set_cursor request. Notification that this seat's pointer is no longer focused on a certain surface. The leave notification is sent before the enter notification for the new focus. Notification of pointer location change. The arguments surface_x and surface_y are the location relative to the focused surface. Describes the physical state of a button that produced the button event. Mouse button click and release notifications. The location of the click is given by the last motion or enter event. The time argument is a timestamp with millisecond granularity, with an undefined base. The button is a button code as defined in the Linux kernel's linux/input-event-codes.h header file, e.g. BTN_LEFT. Any 16-bit button code value is reserved for future additions to the kernel's event code list. All other button codes above 0xFFFF are currently undefined but may be used in future versions of this protocol. Describes the axis types of scroll events. Scroll and other axis notifications. For scroll events (vertical and horizontal scroll axes), the value parameter is the length of a vector along the specified axis in a coordinate space identical to those of motion events, representing a relative movement along the specified axis. For devices that support movements non-parallel to axes multiple axis events will be emitted. When applicable, for example for touch pads, the server can choose to emit scroll events where the motion vector is equivalent to a motion event vector. When applicable, a client can transform its content relative to the scroll distance. Using this request a client can tell the server that it is not going to use the pointer object anymore. This request destroys the pointer proxy object, so clients must not call wl_pointer_destroy() after using this request. Indicates the end of a set of events that logically belong together. A client is expected to accumulate the data in all events within the frame before proceeding. All wl_pointer events before a wl_pointer.frame event belong logically together. For example, in a diagonal scroll motion the compositor will send an optional wl_pointer.axis_source event, two wl_pointer.axis events (horizontal and vertical) and finally a wl_pointer.frame event. The client may use this information to calculate a diagonal vector for scrolling. When multiple wl_pointer.axis events occur within the same frame, the motion vector is the combined motion of all events. When a wl_pointer.axis and a wl_pointer.axis_stop event occur within the same frame, this indicates that axis movement in one axis has stopped but continues in the other axis. When multiple wl_pointer.axis_stop events occur within the same frame, this indicates that these axes stopped in the same instance. A wl_pointer.frame event is sent for every logical event group, even if the group only contains a single wl_pointer event. Specifically, a client may get a sequence: motion, frame, button, frame, axis, frame, axis_stop, frame. The wl_pointer.enter and wl_pointer.leave events are logical events generated by the compositor and not the hardware. These events are also grouped by a wl_pointer.frame. When a pointer moves from one surface to another, a compositor should group the wl_pointer.leave event within the same wl_pointer.frame. However, a client must not rely on wl_pointer.leave and wl_pointer.enter being in the same wl_pointer.frame. Compositor-specific policies may require the wl_pointer.leave and wl_pointer.enter event being split across multiple wl_pointer.frame groups. Describes the source types for axis events. This indicates to the client how an axis event was physically generated; a client may adjust the user interface accordingly. For example, scroll events from a "finger" source may be in a smooth coordinate space with kinetic scrolling whereas a "wheel" source may be in discrete steps of a number of lines. The "continuous" axis source is a device generating events in a continuous coordinate space, but using something other than a finger. One example for this source is button-based scrolling where the vertical motion of a device is converted to scroll events while a button is held down. The "wheel tilt" axis source indicates that the actual device is a wheel but the scroll event is not caused by a rotation but a (usually sideways) tilt of the wheel. Source information for scroll and other axes. This event does not occur on its own. It is sent before a wl_pointer.frame event and carries the source information for all events within that frame. The source specifies how this event was generated. If the source is wl_pointer.axis_source.finger, a wl_pointer.axis_stop event will be sent when the user lifts the finger off the device. If the source is wl_pointer.axis_source.wheel, wl_pointer.axis_source.wheel_tilt or wl_pointer.axis_source.continuous, a wl_pointer.axis_stop event may or may not be sent. Whether a compositor sends an axis_stop event for these sources is hardware-specific and implementation-dependent; clients must not rely on receiving an axis_stop event for these scroll sources and should treat scroll sequences from these scroll sources as unterminated by default. This event is optional. If the source is unknown for a particular axis event sequence, no event is sent. Only one wl_pointer.axis_source event is permitted per frame. The order of wl_pointer.axis_discrete and wl_pointer.axis_source is not guaranteed. Stop notification for scroll and other axes. For some wl_pointer.axis_source types, a wl_pointer.axis_stop event is sent to notify a client that the axis sequence has terminated. This enables the client to implement kinetic scrolling. See the wl_pointer.axis_source documentation for information on when this event may be generated. Any wl_pointer.axis events with the same axis_source after this event should be considered as the start of a new axis motion. The timestamp is to be interpreted identical to the timestamp in the wl_pointer.axis event. The timestamp value may be the same as a preceding wl_pointer.axis event. Discrete step information for scroll and other axes. This event carries the axis value of the wl_pointer.axis event in discrete steps (e.g. mouse wheel clicks). This event does not occur on its own, it is coupled with a wl_pointer.axis event that represents this axis value on a continuous scale. The protocol guarantees that each axis_discrete event is always followed by exactly one axis event with the same axis number within the same wl_pointer.frame. Note that the protocol allows for other events to occur between the axis_discrete and its coupled axis event, including other axis_discrete or axis events. This event is optional; continuous scrolling devices like two-finger scrolling on touchpads do not have discrete steps and do not generate this event. The discrete value carries the directional information. e.g. a value of -2 is two steps towards the negative direction of this axis. The axis number is identical to the axis number in the associated axis event. The order of wl_pointer.axis_discrete and wl_pointer.axis_source is not guaranteed. The wl_keyboard interface represents one or more keyboards associated with a seat. This specifies the format of the keymap provided to the client with the wl_keyboard.keymap event. This event provides a file descriptor to the client which can be memory-mapped to provide a keyboard mapping description. From version 7 onwards, the fd must be mapped with MAP_PRIVATE by the recipient, as MAP_SHARED may fail. Notification that this seat's keyboard focus is on a certain surface. Notification that this seat's keyboard focus is no longer on a certain surface. The leave notification is sent before the enter notification for the new focus. Describes the physical state of a key that produced the key event. A key was pressed or released. The time argument is a timestamp with millisecond granularity, with an undefined base. Notifies clients that the modifier and/or group state has changed, and it should update its local state. Informs the client about the keyboard's repeat rate and delay. This event is sent as soon as the wl_keyboard object has been created, and is guaranteed to be received by the client before any key press event. Negative values for either rate or delay are illegal. A rate of zero will disable any repeating (regardless of the value of delay). This event can be sent later on as well with a new value if necessary, so clients should continue listening for the event past the creation of wl_keyboard. The wl_touch interface represents a touchscreen associated with a seat. Touch interactions can consist of one or more contacts. For each contact, a series of events is generated, starting with a down event, followed by zero or more motion events, and ending with an up event. Events relating to the same contact point can be identified by the ID of the sequence. A new touch point has appeared on the surface. This touch point is assigned a unique ID. Future events from this touch point reference this ID. The ID ceases to be valid after a touch up event and may be reused in the future. The touch point has disappeared. No further events will be sent for this touch point and the touch point's ID is released and may be reused in a future touch down event. A touch point has changed coordinates. Indicates the end of a set of events that logically belong together. A client is expected to accumulate the data in all events within the frame before proceeding. A wl_touch.frame terminates at least one event but otherwise no guarantee is provided about the set of events within a frame. A client must assume that any state not updated in a frame is unchanged from the previously known state. Sent if the compositor decides the touch stream is a global gesture. No further events are sent to the clients from that particular gesture. Touch cancellation applies to all touch points currently active on this client's surface. The client is responsible for finalizing the touch points, future touch points on this surface may reuse the touch point ID. Sent when a touchpoint has changed its shape. This event does not occur on its own. It is sent before a wl_touch.frame event and carries the new shape information for any previously reported, or new touch points of that frame. Other events describing the touch point such as wl_touch.down, wl_touch.motion or wl_touch.orientation may be sent within the same wl_touch.frame. A client should treat these events as a single logical touch point update. The order of wl_touch.shape, wl_touch.orientation and wl_touch.motion is not guaranteed. A wl_touch.down event is guaranteed to occur before the first wl_touch.shape event for this touch ID but both events may occur within the same wl_touch.frame. A touchpoint shape is approximated by an ellipse through the major and minor axis length. The major axis length describes the longer diameter of the ellipse, while the minor axis length describes the shorter diameter. Major and minor are orthogonal and both are specified in surface-local coordinates. The center of the ellipse is always at the touchpoint location as reported by wl_touch.down or wl_touch.move. This event is only sent by the compositor if the touch device supports shape reports. The client has to make reasonable assumptions about the shape if it did not receive this event. Sent when a touchpoint has changed its orientation. This event does not occur on its own. It is sent before a wl_touch.frame event and carries the new shape information for any previously reported, or new touch points of that frame. Other events describing the touch point such as wl_touch.down, wl_touch.motion or wl_touch.shape may be sent within the same wl_touch.frame. A client should treat these events as a single logical touch point update. The order of wl_touch.shape, wl_touch.orientation and wl_touch.motion is not guaranteed. A wl_touch.down event is guaranteed to occur before the first wl_touch.orientation event for this touch ID but both events may occur within the same wl_touch.frame. The orientation describes the clockwise angle of a touchpoint's major axis to the positive surface y-axis and is normalized to the -180 to +180 degree range. The granularity of orientation depends on the touch device, some devices only support binary rotation values between 0 and 90 degrees. This event is only sent by the compositor if the touch device supports orientation reports. An output describes part of the compositor geometry. The compositor works in the 'compositor coordinate system' and an output corresponds to a rectangular area in that space that is actually visible. This typically corresponds to a monitor that displays part of the compositor space. This object is published as global during start up, or when a monitor is hotplugged. This enumeration describes how the physical pixels on an output are laid out. This describes the transform that a compositor will apply to a surface to compensate for the rotation or mirroring of an output device. The flipped values correspond to an initial flip around a vertical axis followed by rotation. The purpose is mainly to allow clients to render accordingly and tell the compositor, so that for fullscreen surfaces, the compositor will still be able to scan out directly from client surfaces. The geometry event describes geometric properties of the output. The event is sent when binding to the output object and whenever any of the properties change. The physical size can be set to zero if it doesn't make sense for this output (e.g. for projectors or virtual outputs). Note: wl_output only advertises partial information about the output position and identification. Some compositors, for instance those not implementing a desktop-style output layout or those exposing virtual outputs, might fake this information. Instead of using x and y, clients should use xdg_output.logical_position. Instead of using make and model, clients should use xdg_output.name and xdg_output.description. These flags describe properties of an output mode. They are used in the flags bitfield of the mode event. The mode event describes an available mode for the output. The event is sent when binding to the output object and there will always be one mode, the current mode. The event is sent again if an output changes mode, for the mode that is now current. In other words, the current mode is always the last mode that was received with the current flag set. The size of a mode is given in physical hardware units of the output device. This is not necessarily the same as the output size in the global compositor space. For instance, the output may be scaled, as described in wl_output.scale, or transformed, as described in wl_output.transform. Clients willing to retrieve the output size in the global compositor space should use xdg_output.logical_size instead. The vertical refresh rate can be set to zero if it doesn't make sense for this output (e.g. for virtual outputs). Clients should not use the refresh rate to schedule frames. Instead, they should use the wl_surface.frame event or the presentation-time protocol. Note: this information is not always meaningful for all outputs. Some compositors, such as those exposing virtual outputs, might fake the refresh rate or the size. This event is sent after all other properties have been sent after binding to the output object and after any other property changes done after that. This allows changes to the output properties to be seen as atomic, even if they happen via multiple events. This event contains scaling geometry information that is not in the geometry event. It may be sent after binding the output object or if the output scale changes later. If it is not sent, the client should assume a scale of 1. A scale larger than 1 means that the compositor will automatically scale surface buffers by this amount when rendering. This is used for very high resolution displays where applications rendering at the native resolution would be too small to be legible. It is intended that scaling aware clients track the current output of a surface, and if it is on a scaled output it should use wl_surface.set_buffer_scale with the scale of the output. That way the compositor can avoid scaling the surface, and the client can supply a higher detail image. Using this request a client can tell the server that it is not going to use the output object anymore. A region object describes an area. Region objects are used to describe the opaque and input regions of a surface. Destroy the region. This will invalidate the object ID. Add the specified rectangle to the region. Subtract the specified rectangle from the region. The global interface exposing sub-surface compositing capabilities. A wl_surface, that has sub-surfaces associated, is called the parent surface. Sub-surfaces can be arbitrarily nested and create a tree of sub-surfaces. The root surface in a tree of sub-surfaces is the main surface. The main surface cannot be a sub-surface, because sub-surfaces must always have a parent. A main surface with its sub-surfaces forms a (compound) window. For window management purposes, this set of wl_surface objects is to be considered as a single window, and it should also behave as such. The aim of sub-surfaces is to offload some of the compositing work within a window from clients to the compositor. A prime example is a video player with decorations and video in separate wl_surface objects. This should allow the compositor to pass YUV video buffer processing to dedicated overlay hardware when possible. Informs the server that the client will not be using this protocol object anymore. This does not affect any other objects, wl_subsurface objects included. Create a sub-surface interface for the given surface, and associate it with the given parent surface. This turns a plain wl_surface into a sub-surface. The to-be sub-surface must not already have another role, and it must not have an existing wl_subsurface object. Otherwise a protocol error is raised. Adding sub-surfaces to a parent is a double-buffered operation on the parent (see wl_surface.commit). The effect of adding a sub-surface becomes visible on the next time the state of the parent surface is applied. This request modifies the behaviour of wl_surface.commit request on the sub-surface, see the documentation on wl_subsurface interface. An additional interface to a wl_surface object, which has been made a sub-surface. A sub-surface has one parent surface. A sub-surface's size and position are not limited to that of the parent. Particularly, a sub-surface is not automatically clipped to its parent's area. A sub-surface becomes mapped, when a non-NULL wl_buffer is applied and the parent surface is mapped. The order of which one happens first is irrelevant. A sub-surface is hidden if the parent becomes hidden, or if a NULL wl_buffer is applied. These rules apply recursively through the tree of surfaces. The behaviour of a wl_surface.commit request on a sub-surface depends on the sub-surface's mode. The possible modes are synchronized and desynchronized, see methods wl_subsurface.set_sync and wl_subsurface.set_desync. Synchronized mode caches the wl_surface state to be applied when the parent's state gets applied, and desynchronized mode applies the pending wl_surface state directly. A sub-surface is initially in the synchronized mode. Sub-surfaces have also other kind of state, which is managed by wl_subsurface requests, as opposed to wl_surface requests. This state includes the sub-surface position relative to the parent surface (wl_subsurface.set_position), and the stacking order of the parent and its sub-surfaces (wl_subsurface.place_above and .place_below). This state is applied when the parent surface's wl_surface state is applied, regardless of the sub-surface's mode. As the exception, set_sync and set_desync are effective immediately. The main surface can be thought to be always in desynchronized mode, since it does not have a parent in the sub-surfaces sense. Even if a sub-surface is in desynchronized mode, it will behave as in synchronized mode, if its parent surface behaves as in synchronized mode. This rule is applied recursively throughout the tree of surfaces. This means, that one can set a sub-surface into synchronized mode, and then assume that all its child and grand-child sub-surfaces are synchronized, too, without explicitly setting them. If the wl_surface associated with the wl_subsurface is destroyed, the wl_subsurface object becomes inert. Note, that destroying either object takes effect immediately. If you need to synchronize the removal of a sub-surface to the parent surface update, unmap the sub-surface first by attaching a NULL wl_buffer, update parent, and then destroy the sub-surface. If the parent wl_surface object is destroyed, the sub-surface is unmapped. The sub-surface interface is removed from the wl_surface object that was turned into a sub-surface with a wl_subcompositor.get_subsurface request. The wl_surface's association to the parent is deleted, and the wl_surface loses its role as a sub-surface. The wl_surface is unmapped immediately. This schedules a sub-surface position change. The sub-surface will be moved so that its origin (top left corner pixel) will be at the location x, y of the parent surface coordinate system. The coordinates are not restricted to the parent surface area. Negative values are allowed. The scheduled coordinates will take effect whenever the state of the parent surface is applied. When this happens depends on whether the parent surface is in synchronized mode or not. See wl_subsurface.set_sync and wl_subsurface.set_desync for details. If more than one set_position request is invoked by the client before the commit of the parent surface, the position of a new request always replaces the scheduled position from any previous request. The initial position is 0, 0. This sub-surface is taken from the stack, and put back just above the reference surface, changing the z-order of the sub-surfaces. The reference surface must be one of the sibling surfaces, or the parent surface. Using any other surface, including this sub-surface, will cause a protocol error. The z-order is double-buffered. Requests are handled in order and applied immediately to a pending state. The final pending state is copied to the active state the next time the state of the parent surface is applied. When this happens depends on whether the parent surface is in synchronized mode or not. See wl_subsurface.set_sync and wl_subsurface.set_desync for details. A new sub-surface is initially added as the top-most in the stack of its siblings and parent. The sub-surface is placed just below the reference surface. See wl_subsurface.place_above. Change the commit behaviour of the sub-surface to synchronized mode, also described as the parent dependent mode. In synchronized mode, wl_surface.commit on a sub-surface will accumulate the committed state in a cache, but the state will not be applied and hence will not change the compositor output. The cached state is applied to the sub-surface immediately after the parent surface's state is applied. This ensures atomic updates of the parent and all its synchronized sub-surfaces. Applying the cached state will invalidate the cache, so further parent surface commits do not (re-)apply old state. See wl_subsurface for the recursive effect of this mode. Change the commit behaviour of the sub-surface to desynchronized mode, also described as independent or freely running mode. In desynchronized mode, wl_surface.commit on a sub-surface will apply the pending state directly, without caching, as happens normally with a wl_surface. Calling wl_surface.commit on the parent surface has no effect on the sub-surface's wl_surface state. This mode allows a sub-surface to be updated on its own. If cached state exists when wl_surface.commit is called in desynchronized mode, the pending state is added to the cached state, and applied as a whole. This invalidates the cache. Note: even if a sub-surface is set to desynchronized, a parent sub-surface may override it to behave as synchronized. For details, see wl_subsurface. If a surface's parent surface behaves as desynchronized, then the cached state is applied on set_desync. wayland-1.18.0/protocol/tests.xml0000644000175000017500000000402613620636273016035 0ustar zumbizumbi Copyright © 2017 Samsung Electronics Co., Ltd Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice (including the next paragraph) shall be included in all copies or substantial portions of the Software.

Wayland is [hosted on freedesktop.org's GitLab](https://gitlab.freedesktop.org/wayland/wayland/): in order to submit code, you should create an account on this GitLab instance, fork the core Wayland repository, push your changes to a branch in your new repository, and then submit these patches for review through a merge request. Wayland formerly accepted patches via `git-send-email`, sent to **wayland-devel@lists.freedesktop.org**; these were [tracked using Patchwork](https://patchwork.freedesktop.org/project/wayland/). Some old patches continue to be sent this way, and we may accept small new patches sent to the list, but please send all new patches through GitLab merge requests. Formatting and separating commits --------------------------------- Unlike many projects using GitHub and GitLab, Wayland has a [linear, 'recipe' style history](http://www.bitsnbites.eu/git-history-work-log-vs-recipe/). This means that every commit should be small, digestible, stand-alone, and functional. Rather than a purely chronological commit history like this: connection: plug a fd leak plug another fd leak connection: init fds to -1 close all fds refactor checks into a new function don't close fds we handed out we aim to have a clean history which only reflects the final state, broken up into functional groupings: connection: Refactor out closure allocation connection: Clear fds we shouldn't close to -1 connection: Make wl_closure_destroy() close fds of undispatched closures This ensures that the final patch series only contains the final state, without the changes and missteps taken along the development process. The first line of a commit message should contain a prefix indicating what part is affected by the patch followed by one sentence that describes the change. For examples: protocol: Support scaled outputs and surfaces and doc: generate server documentation from XML too If in doubt what prefix to use, look at other commits that change the same file(s) as the patch being sent. The body of the commit message should describe what the patch changes and why, and also note any particular side effects. This shouldn't be empty on most of the cases. It shouldn't take a lot of effort to write a commit message for an obvious change, so an empty commit message body is only acceptable if the questions "What?" and "Why?" are already answered on the one-line summary. The lines of the commit message should have at most 76 characters, to cope with the way git log presents them. See [notes on commit messages] for a recommended reading on writing commit messages. Your patches should also include a Signed-off-by line with your name and email address. If you're not the patch's original author, you should also gather S-o-b's by them (and/or whomever gave the patch to you.) The significance of this is that it certifies that you created the patch, that it was created under an appropriate open source license, or provided to you under those terms. This lets us indicate a chain of responsibility for the copyright status of the code. We won't reject patches that lack S-o-b, but it is strongly recommended. When you re-send patches, revised or not, it would be very good to document the changes compared to the previous revision in the commit message and/or the merge request. If you have already received Reviewed-by or Acked-by tags, you should evaluate whether they still apply and include them in the respective commit messages. Otherwise the tags may be lost, reviewers miss the credit they deserve, and the patches may cause redundant review effort. Tracking patches and following up --------------------------------- Once submitted to GitLab, your patches will be reviewed by the Wayland development team on GitLab. Review may be entirely positive and result in your code landing instantly, in which case, great! You're done. However, we may ask you to make some revisions: fixing some bugs we've noticed, working to a slightly different design, or adding documentation and tests. If you do get asked to revise the patches, please bear in mind the notes above. You should use `git rebase -i` to make revisions, so that your patches follow the clear linear split documented above. Following that split makes it easier for reviewers to understand your work, and to verify that the code you're submitting is correct. A common request is to split single large patch into multiple patches. This can happen, for example, if when adding a new feature you notice a bug elsewhere which you need to fix to progress. Separating these changes into separate commits will allow us to verify and land the bugfix quickly, pushing part of your work for the good of everyone, whilst revision and discussion continues on the larger feature part. It also allows us to direct you towards reviewers who best understand the different areas you are working on. When you have made any requested changes, please rebase the commits, verify that they still individually look good, then force-push your new branch to GitLab. This will update the merge request and notify everyone subscribed to your merge request, so they can review it again. There are also [many GitLab CLI clients](https://about.gitlab.com/applications/#cli-clients), if you prefer to avoid the web interface. It may be difficult to follow review comments without using the web interface though, so we do recommend using this to go through the review process, even if you use other clients to track the list of available patches. Coding style ------------ You should follow the style of the file you're editing. In general, we try to follow the rules below. **Note: this file uses spaces due to markdown rendering issues for tabs. Code must be implemented using tabs.** - indent with tabs, and a tab is always 8 characters wide - opening braces are on the same line as the if statement; - no braces in an if-body with just one statement; - if one of the branches of an if-else condition has braces, then the other branch should also have braces; - there is always an empty line between variable declarations and the code; ```c static int my_function(void) { int a = 0; if (a) b(); else c(); if (a) { b(); c(); } else { d(); } } ``` - lines should be less than 80 characters wide; - when breaking lines with functions calls, the parameters are aligned with the opening parentheses; - when assigning a variable with the result of a function call, if the line would be longer we break it around the equal '=' sign if it makes sense; ```c long_variable_name = function_with_a_really_long_name(parameter1, parameter2, parameter3, parameter4); x = function_with_a_really_long_name(parameter1, parameter2, parameter3, parameter4); ``` Conduct ======= As a freedesktop.org project, Wayland follows the Contributor Covenant, found at: https://www.freedesktop.org/wiki/CodeOfConduct Please conduct yourself in a respectful and civilised manner when interacting with community members on mailing lists, IRC, or bug trackers. The community represents the project as a whole, and abusive or bullying behaviour is not tolerated by the project. Licensing ========= Wayland is licensed with the intention to be usable anywhere X.org is. Originally, X.org was covered under the MIT X11 license, but changed to the MIT Expat license. Similarly, Wayland was covered initially as MIT X11 licensed, but changed to the MIT Expat license, following in X.org's footsteps. Other than wording, the two licenses are substantially the same, with the exception of a no-advertising clause in X11 not included in Expat. New source code files should specify the MIT Expat license in their boilerplate, as part of the copyright statement. Review ====== All patches, even trivial ones, require at least one positive review (Reviewed-by). Additionally, if no Reviewed-by's have been given by people with commit access, there needs to be at least one Acked-by from someone with commit access. A person with commit access is expected to be able to evaluate the patch with respect to the project scope and architecture. The below review guidelines are intended to be interpreted in spirit, not by the letter. There may be circumstances where some guidelines are better ignored. We rely very much on the judgement of reviewers and commit rights holders. During review, the following matters should be checked: - The commit message explains why the change is being made. - The code fits the project's scope. - The code license is the same MIT licence the project generally uses. - Stable ABI or API is not broken. - Stable ABI or API additions must be justified by actual use cases, not only by speculation. They must also be documented, and it is strongly recommended to include tests excercising the additions in the test suite. - The code fits the existing software architecture, e.g. no layering violations. - The code is correct and does not introduce new failures for existing users, does not add new corner-case bugs, and does not introduce new compiler warnings. - The patch does what it says in the commit message and changes nothing else. - The patch is a single logical change. If the commit message addresses multiple points, it is a hint that the commit might need splitting up. - A bug fix should target the underlying root cause instead of hiding symptoms. If a complete fix is not practical, partial fixes are acceptable if they come with code comments and filed Gitlab issues for the remaining bugs. - The bug root cause rule applies to external software components as well, e.g. do not work around kernel driver issues in userspace. - The test suite passes. - The code does not depend on API or ABI which has no working free open source implementation. - The code is not dead or untestable. E.g. if there are no free open source software users for it then it is effectively dead code. - The code is written to be easy to understand, or if code cannot be clear enough on its own there are code comments to explain it. - The code is minimal, i.e. prefer refactor and re-use when possible unless clarity suffers. - The code adheres to the style guidelines. - In a patch series, every intermediate step adheres to the above guidelines. Commit rights ============= Commit rights will be granted to anyone who requests them and fulfills the below criteria: - Submitted some (10 as a rule of thumb) non-trivial (not just simple spelling fixes and whitespace adjustment) patches that have been merged already. - Are actively participating in public discussions about their work (on the mailing list or IRC). This should not be interpreted as a requirement to review other peoples patches but just make sure that patch submission isn't one-way communication. Cross-review is still highly encouraged. - Will be regularly contributing further patches. This includes regular contributors to other parts of the open source graphics stack who only do the occasional development in this project. - Agrees to use their commit rights in accordance with the documented merge criteria, tools, and processes. To apply for commit rights, create a new issue in gitlab for the respective project and give it the "accounts" label. Committers are encouraged to request their commit rights get removed when they no longer contribute to the project. Commit rights will be reinstated when they come back to the project. Maintainers and committers should encourage contributors to request commit rights, especially junior contributors tend to underestimate their skills. Stabilising for releases ======================== A release cycle ends with a stable release which also starts a new cycle and lifts any code freezes. Gradual code freezing towards a stable release starts with an alpha release. The release stages of a cycle are: - **Alpha release**: Signified by version number #.#.91. Major features must have landed before this. Major features include invasive code motion and refactoring, high risk changes, and new stable library ABI. - **Beta release**: Signified by version number #.#.92. Minor features must have landed before this. Minor features include all new features that are not major, low risk changes, clean-ups, and documentation. Stable ABI that was new in the alpha release can be removed before a beta release if necessary. - **Release candidates (RC)**: Signified by version number #.#.93 and up to #.#.99. Bug fixes that are not release critical must have landed before this. Release critical bug fixes can still be landed after this, but they may call for another RC. - **Stable release**: Signified by version number #.#.0. Ideally no changes since the last RC. Mind that version #.#.90 is never released. It is used during development when no code freeze is in effect. Stable branches and point releases are not covered by the above.

It is created with either \ref wl_display_connect() or * \ref wl_display_connect_to_fd(). A connection is terminated using * \ref wl_display_disconnect(). * * A wl_display is also used as the \ref wl_proxy for the wl_display * singleton object on the compositor side. * * A wl_display object handles all the data sent from and to the * compositor. When a \ref wl_proxy marshals a request, it will write its wire * representation to the display's write buffer. The data is sent to the * compositor when the client calls \ref wl_display_flush(). * * Incoming data is handled in two steps: queueing and dispatching. In the * queue step, the data coming from the display fd is interpreted and * added to a queue. On the dispatch step, the handler for the incoming * event set by the client on the corresponding \ref wl_proxy is called. * * A wl_display has at least one event queue, called the default * queue. Clients can create additional event queues with \ref * wl_display_create_queue() and assign \ref wl_proxy's to it. Events * occurring in a particular proxy are always queued in its assigned queue. * A client can ensure that a certain assumption, such as holding a lock * or running from a given thread, is true when a proxy event handler is * called by assigning that proxy to an event queue and making sure that * this queue is only dispatched when the assumption holds. * * The default queue is dispatched by calling \ref wl_display_dispatch(). * This will dispatch any events queued on the default queue and attempt * to read from the display fd if it's empty. Events read are then queued * on the appropriate queues according to the proxy assignment. * * A user created queue is dispatched with \ref wl_display_dispatch_queue(). * This function behaves exactly the same as wl_display_dispatch() * but it dispatches given queue instead of the default queue. * * A real world example of event queue usage is Mesa's implementation of * eglSwapBuffers() for the Wayland platform. This function might need * to block until a frame callback is received, but dispatching the default * queue could cause an event handler on the client to start drawing * again. This problem is solved using another event queue, so that only * the events handled by the EGL code are dispatched during the block. * * This creates a problem where a thread dispatches a non-default * queue, reading all the data from the display fd. If the application * would call \em poll(2) after that it would block, even though there * might be events queued on the default queue. Those events should be * dispatched with \ref wl_display_dispatch_pending() or \ref * wl_display_dispatch_queue_pending() before flushing and blocking. */ struct wl_display; /** \class wl_event_queue * * \brief A queue for \ref wl_proxy object events. * * Event queues allows the events on a display to be handled in a thread-safe * manner.

The * protocol implementation uses a wl_message within its demarshal machinery for * decoding messages between a compositor and its clients. In a sense, a * wl_message is to a protocol message like a class is to an object. * * The `name` of a wl_message is the name of the corresponding protocol message. * * The `signature` is an ordered list of symbols representing the data types * of message arguments and, optionally, a protocol version and indicators for * nullability. A leading integer in the `signature` indicates the _since_ * version of the protocol message. A `?` preceding a data type symbol indicates * that the following argument type is nullable. While it is a protocol violation * to send messages with non-nullable arguments set to `NULL`, event handlers in * clients might still get called with non-nullable object arguments set to * `NULL`. This can happen when the client destroyed the object being used as * argument on its side and an event referencing that object was sent before the * server knew about its destruction. As this race cannot be prevented, clients * should - as a general rule - program their event handlers such that they can * handle object arguments declared non-nullable being `NULL` gracefully. * * When no arguments accompany a message, `signature` is an empty string. * * Symbols: * * * `i`: int * * `u`: uint * * `f`: fixed * * `s`: string * * `o`: object * * `n`: new_id * * `a`: array * * `h`: fd * * `?`: following argument is nullable * * While demarshaling primitive arguments is straightforward, when demarshaling * messages containing `object` or `new_id` arguments, the protocol * implementation often must determine the type of the object. The `types` of a * wl_message is an array of wl_interface references that correspond to `o` and * `n` arguments in `signature`, with `NULL` placeholders for arguments with * non-object types. * * Consider the protocol event wl_display `delete_id` that has a single `uint` * argument. The wl_message is: * * \code * { "delete_id", "u", [NULL] } * \endcode * * Here, the message `name` is `"delete_id"`, the `signature` is `"u"`, and the * argument `types` is `[NULL]`, indicating that the `uint` argument has no * corresponding wl_interface since it is a primitive argument. * * In contrast, consider a `wl_foo` interface supporting protocol request `bar` * that has existed since version 2, and has two arguments: a `uint` and an * object of type `wl_baz_interface` that may be `NULL`. Such a `wl_message` * might be: * * \code * { "bar", "2u?o", [NULL, &wl_baz_interface] } * \endcode * * Here, the message `name` is `"bar"`, and the `signature` is `"2u?o"`. Notice * how the `2` indicates the protocol version, the `u` indicates the first * argument type is `uint`, and the `?o` indicates that the second argument * is an object that may be `NULL`.

ICCCM - mime-type guidelines for data_source (ie, both dnd and selection): recommended types for text or images, types that a clipboard manager must support, mime-types must be listed in preferred order - we need a "no kb focus please" mechanism. Or should this be implicit in a specific surface type? EWMH - configure should provide dx_left, dx_right, dy_top, dy_bottom, or dx, dy, width and height. - move to workspace, keep on top, on all workspaces, minimize etc requests for implementing client side window menu? or just make a "show window menu" request to let the compositor display and manage a popup window? - window move and resize functionality for kb and touch. - Protocol for specifying title bar rectangle (for moving unresponsive apps). Rectangle for close button, so we can popup force-close dialog if application doesn't respond to ping event when user clicks there. We could use the region mechanism here too. - popup placement protocol logic. - subsurface mechanism. we need this for cases where we would use an X subwindow for gl or video other different visual type. EGL/gbm - Land Robert Braggs EGL extensions: frame age, swap with damage - Make it possible to share buffers from compositor to clients. Tricky part here is how to indicate to EGL on the server side that it should make an EGLImage available to a client. We'll need a "create a wl_buffer for this EGLImage for this client" kind of entry point. - Protocol for arbitrating access to scanout buffers (physically contiguous memory). When a client goes fullscreen (or ideally as the compositor starts the animation that will make it fullscreen) we send a "give up your scanout buffer" to the current fullscreen client (if any) and when the client acks that we send a "try to allocate a scanout buffer now" event to the fullscreen-to-be client. Misc - glyph cache - Needs a mechanism to pass buffers to client. buffer = drm.create_buffer(); /* buffer with stuff in it */ cache.upload(buffer, x, y, width, height, int hash) drm.buffer: id, name, stride etc /* event to announce cache buffer */ cache.image: hash, buffer, x, y, stride /* event to announce * location in cache */ cache.reject: hash /* no upload for you! */ cache.retire: buffer /* cache has stopped using buffer, please * reupload whatever you had in that buffer */ - A "please suspend" event from the compositor, to indicate to an application that it's no longer visible/active. Or maybe discard buffer, as in "wayland discarded your buffer, it's no longer visible, you can stop updating it now.", reattach, as in "oh hey, I'm about to show your buffer that I threw away, what was it again?". for wayland system compositor vt switcing, for example, to be able to throw away the surfaces in the session we're switching away from. for minimized windows that we don't want live thumb nails for. etc. Clients and ports - port gtk+ - draw window decorations in gtkwindow.c - Details about pointer grabs. wayland doesn't have active grabs, menus will behave subtly different. Under X, clicking a menu open grabs the pointer and clicking outside the window pops down the menu and swallows the click. without active grabs we can't swallow the click. I'm sure there much more... - dnd, copy-paste - Investigate DirectFB on Wayland (or is that Wayland on DirectFB?) Ideas - A wayland settings protocol to tell clients about themes (icons, cursors, widget themes), fonts details (family, hinting preferences) etc. Just send all settings at connect time, send updates when a setting change. Getting a little close to gconf here, but could be pretty simple: interface "settings": event int_value(string name, int value) event string_value(string name, string value) but maybe it's better to just require that clients get that from somewhere else (gconf/dbus). Crazy ideas - AF_WAYLAND - A new socket type. Eliminate compositor context switch by making kernel understand enough of wayland that it can forward input events as wayland events and do page flipping in response to surface_attach requests: - ioctl(wayland_fd, "surface_attach to object 5 should do a kms page flip on ctrc 2"); - what about multiple crtcs? what about frame event for other clients? - forward these input devices to the client - "scancode 124 pressed or released with scan codes 18,22 and 30 held down gives control back to userspace wayland. - what about maintaining cursor position? what about pointer acceleration? maybe this only works in "client cursor mode", where wayland hides the cursor and only sends relative events? Solves the composited cursor problem. How does X show its cursor then? - Probably not worth it. wayland-1.18.0/Makefile.am0000644000175000017500000002352413620636273014350 0ustar zumbizumbiif BUILD_DOCS SUBDIRS = doc endif ACLOCAL_AMFLAGS

Wayland is a project to define a protocol for a compositor to talk to its clients as well as a library implementation of the protocol. The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X application, or a wayland client itself. The clients can be traditional applications, X servers (rootless or fullscreen) or other display servers. The wayland protocol is essentially only about input handling and buffer management. The compositor receives input events and forwards them to the relevant client. The clients creates buffers and renders into them and notifies the compositor when it needs to redraw. The protocol also handles drag and drop, selections, window management and other interactions that must go through the compositor. However, the protocol does not handle rendering, which is one of the features that makes wayland so simple. All clients are expected to handle rendering themselves, typically through cairo or OpenGL. The weston compositor is a reference implementation of a wayland compositor and the weston repository also includes a few example clients. Building the wayland libraries is fairly simple, aside from libffi, they don't have many dependencies: $ git clone https://gitlab.freedesktop.org/wayland/wayland $ cd wayland $ ./autogen.sh --prefix=PREFIX $ make $ make install where PREFIX is where you want to install the libraries. See https://wayland.freedesktop.org for more complete build instructions for wayland, weston, xwayland and various toolkits. wayland-1.18.0/Makefile.in0000644000175000017500000044577013620636304014367 0ustar zumbizumbi# Makefile.in generated by automake 1.16.1 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2018 Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ VPATH = @srcdir@ am__is_gnu_make = { \ if test -z '$(MAKELEVEL)'; then \ false; \ elif test -n '$(MAKE_HOST)'; then \ true; \ elif test -n '$(MAKE_VERSION)' && test -n '$(CURDIR)'; then \ true; \ else \ false; \ fi; \ } am__make_running_with_option = \ case $${target_option-} in \ ?) ;; \ *) echo "am__make_running_with_option: internal error: invalid" \ "target option '$${target_option-}' specified" >&2; \ exit 1;; \ esac; \ has_opt=no; \ sane_makeflags=$$MAKEFLAGS; \ if $(am__is_gnu_make); then \ sane_makeflags=$$MFLAGS; \ else \ case $$MAKEFLAGS in \ *\\[\ \ ]*) \ bs=\\; \ sane_makeflags=`printf '%s\n' "$$MAKEFLAGS" \ | sed "s/$$bs$$bs[$$bs $$bs ]*//g"`;; \ esac; \ fi; \ skip_next=no; \ strip_trailopt () \ { \ flg=`printf '%s\n' "$$flg" | sed "s/$$1.*$$//"`; \ }; \ for flg in $$sane_makeflags; do \ test $$skip_next = yes && { skip_next=no; continue; }; \ case $$flg in \ *=*|--*) continue;; \ -*I) strip_trailopt 'I'; skip_next=yes;; \ -*I?*) strip_trailopt 'I';; \ -*O) strip_trailopt 'O'; skip_next=yes;; \ -*O?*) strip_trailopt 'O';; \ -*l) strip_trailopt 'l'; skip_next=yes;; \ -*l?*) strip_trailopt 'l';; \ -[dEDm]) skip_next=yes;; \ -[JT]) skip_next=yes;; \ esac; \ case $$flg in \ *$$target_option*) has_opt=yes; break;; \ esac; \ done; \ test $$has_opt = yes am__make_dryrun = (target_option=n; $(am__make_running_with_option)) am__make_keepgoing = (target_option=k; $(am__make_running_with_option)) pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ bin_PROGRAMS = wayland-scanner$(EXEEXT) @DTD_VALIDATION_TRUE@am__append_1 = src/dtddata.S @ENABLE_LIBRARIES_TRUE@am__append_2 = libwayland-private.la \ @ENABLE_LIBRARIES_TRUE@ libtest-runner.la libtest-helpers.la @ENABLE_LIBRARIES_TRUE@am__append_3 = src/wayland-client.pc \ @ENABLE_LIBRARIES_TRUE@ src/wayland-server.pc \ @ENABLE_LIBRARIES_TRUE@ cursor/wayland-cursor.pc \ @ENABLE_LIBRARIES_TRUE@ egl/wayland-egl.pc \ @ENABLE_LIBRARIES_TRUE@ egl/wayland-egl-backend.pc @ENABLE_LIBRARIES_TRUE@check_PROGRAMS = \ @ENABLE_LIBRARIES_TRUE@ wayland-egl-abi-check$(EXEEXT) @ENABLE_CPP_TEST_TRUE@@ENABLE_LIBRARIES_TRUE@am__append_4 = cpp-compile-test @ENABLE_LIBRARIES_TRUE@TESTS = $(am__EXEEXT_2) \ @ENABLE_LIBRARIES_TRUE@ egl/wayland-egl-symbols-check \ @ENABLE_LIBRARIES_TRUE@ tests/scanner-test.sh @ENABLE_LIBRARIES_TRUE@noinst_PROGRAMS = $(am__EXEEXT_2) \ @ENABLE_LIBRARIES_TRUE@ exec-fd-leak-checker$(EXEEXT) \ @ENABLE_LIBRARIES_TRUE@ fixed-benchmark$(EXEEXT) subdir = .

The core global object. This is a special singleton object. It is used for internal Wayland protocol features. The sync request asks the server to emit the 'done' event on the returned wl_callback object. Since requests are handled in-order and events are delivered in-order, this can be used as a barrier to ensure all previous requests and the resulting events have been handled. The object returned by this request will be destroyed by the compositor after the callback is fired and as such the client must not attempt to use it after that point. The callback_data passed in the callback is the event serial. This request creates a registry object that allows the client to list and bind the global objects available from the compositor. The error event is sent out when a fatal (non-recoverable) error has occurred. The object_id argument is the object where the error occurred, most often in response to a request to that object. The code identifies the error and is defined by the object interface. As such, each interface defines its own set of error codes. The message is a brief description of the error, for (debugging) convenience. These errors are global and can be emitted in response to any server request. This event is used internally by the object ID management logic. When a client deletes an object, the server will send this event to acknowledge that it has seen the delete request. When the client receives this event, it will know that it can safely reuse the object ID. The singleton global registry object. The server has a number of global objects that are available to all clients. These objects typically represent an actual object in the server (for example, an input device) or they are singleton objects that provide extension functionality. When a client creates a registry object, the registry object will emit a global event for each global currently in the registry. Globals come and go as a result of device or monitor hotplugs, reconfiguration or other events, and the registry will send out global and global_remove events to keep the client up to date with the changes. To mark the end of the initial burst of events, the client can use the wl_display.sync request immediately after calling wl_display.get_registry. A client can bind to a global object by using the bind request. This creates a client-side handle that lets the object emit events to the client and lets the client invoke requests on the object. Binds a new, client-created object to the server using the specified name as the identifier. Notify the client of global objects. The event notifies the client that a global object with the given name is now available, and it implements the given version of the given interface. Notify the client of removed global objects. This event notifies the client that the global identified by name is no longer available. If the client bound to the global using the bind request, the client should now destroy that object. The object remains valid and requests to the object will be ignored until the client destroys it, to avoid races between the global going away and a client sending a request to it. Clients can handle the 'done' event to get notified when the related request is done. Notify the client when the related request is done. A compositor. This object is a singleton global. The compositor is in charge of combining the contents of multiple surfaces into one displayable output. Ask the compositor to create a new surface. Ask the compositor to create a new region. The wl_shm_pool object encapsulates a piece of memory shared between the compositor and client. Through the wl_shm_pool object, the client can allocate shared memory wl_buffer objects. All objects created through the same pool share the same underlying mapped memory. Reusing the mapped memory avoids the setup/teardown overhead and is useful when interactively resizing a surface or for many small buffers. Create a wl_buffer object from the pool. The buffer is created offset bytes into the pool and has width and height as specified. The stride argument specifies the number of bytes from the beginning of one row to the beginning of the next. The format is the pixel format of the buffer and must be one of those advertised through the wl_shm.format event. A buffer will keep a reference to the pool it was created from so it is valid to destroy the pool immediately after creating a buffer from it. Destroy the shared memory pool. The mmapped memory will be released when all buffers that have been created from this pool are gone. This request will cause the server to remap the backing memory for the pool from the file descriptor passed when the pool was created, but using the new size. This request can only be used to make the pool bigger. A singleton global object that provides support for shared memory. Clients can create wl_shm_pool objects using the create_pool request. At connection setup time, the wl_shm object emits one or more format events to inform clients about the valid pixel formats that can be used for buffers. These errors can be emitted in response to wl_shm requests. This describes the memory layout of an individual pixel. All renderers should support argb8888 and xrgb8888 but any other formats are optional and may not be supported by the particular renderer in use. The drm format codes match the macros defined in drm_fourcc.h. The formats actually supported by the compositor will be reported by the format event. Create a new wl_shm_pool object. The pool can be used to create shared memory based buffer objects. The server will mmap size bytes of the passed file descriptor, to use as backing memory for the pool. Informs the client about a valid pixel format that can be used for buffers. Known formats include argb8888 and xrgb8888. A buffer provides the content for a wl_surface. Buffers are created through factory interfaces such as wl_drm, wl_shm or similar. It has a width and a height and can be attached to a wl_surface, but the mechanism by which a client provides and updates the contents is defined by the buffer factory interface. Destroy a buffer. If and how you need to release the backing storage is defined by the buffer factory interface. For possible side-effects to a surface, see wl_surface.attach. Sent when this wl_buffer is no longer used by the compositor. The client is now free to reuse or destroy this buffer and its backing storage. If a client receives a release event before the frame callback requested in the same wl_surface.commit that attaches this wl_buffer to a surface, then the client is immediately free to reuse the buffer and its backing storage, and does not need a second buffer for the next surface content update. Typically this is possible, when the compositor maintains a copy of the wl_surface contents, e.g. as a GL texture. This is an important optimization for GL(ES) compositors with wl_shm clients. A wl_data_offer represents a piece of data offered for transfer by another client (the source client). It is used by the copy-and-paste and drag-and-drop mechanisms. The offer describes the different mime types that the data can be converted to and provides the mechanism for transferring the data directly from the source client. Indicate that the client can accept the given mime type, or NULL for not accepted. For objects of version 2 or older, this request is used by the client to give feedback whether the client can receive the given mime type, or NULL if none is accepted; the feedback does not determine whether the drag-and-drop operation succeeds or not. For objects of version 3 or newer, this request determines the final result of the drag-and-drop operation. If the end result is that no mime types were accepted, the drag-and-drop operation will be cancelled and the corresponding drag source will receive wl_data_source.cancelled. Clients may still use this event in conjunction with wl_data_source.action for feedback. To transfer the offered data, the client issues this request and indicates the mime type it wants to receive. The transfer happens through the passed file descriptor (typically created with the pipe system call). The source client writes the data in the mime type representation requested and then closes the file descriptor. The receiving client reads from the read end of the pipe until EOF and then closes its end, at which point the transfer is complete. This request may happen multiple times for different mime types, both before and after wl_data_device.drop. Drag-and-drop destination clients may preemptively fetch data or examine it more closely to determine acceptance. Destroy the data offer. Sent immediately after creating the wl_data_offer object. One event per offered mime type. Notifies the compositor that the drag destination successfully finished the drag-and-drop operation. Upon receiving this request, the compositor will emit wl_data_source.dnd_finished on the drag source client. It is a client error to perform other requests than wl_data_offer.destroy after this one. It is also an error to perform this request after a NULL mime type has been set in wl_data_offer.accept or no action was received through wl_data_offer.action. Sets the actions that the destination side client supports for this operation. This request may trigger the emission of wl_data_source.action and wl_data_offer.action events if the compositor needs to change the selected action. This request can be called multiple times throughout the drag-and-drop operation, typically in response to wl_data_device.enter or wl_data_device.motion events. This request determines the final result of the drag-and-drop operation. If the end result is that no action is accepted, the drag source will receive wl_drag_source.cancelled. The dnd_actions argument must contain only values expressed in the wl_data_device_manager.dnd_actions enum, and the preferred_action argument must only contain one of those values set, otherwise it will result in a protocol error. While managing an "ask" action, the destination drag-and-drop client may perform further wl_data_offer.receive requests, and is expected to perform one last wl_data_offer.set_actions request with a preferred action other than "ask" (and optionally wl_data_offer.accept) before requesting wl_data_offer.finish, in order to convey the action selected by the user. If the preferred action is not in the wl_data_offer.source_actions mask, an error will be raised. If the "ask" action is dismissed (e.g. user cancellation), the client is expected to perform wl_data_offer.destroy right away. This request can only be made on drag-and-drop offers, a protocol error will be raised otherwise. This event indicates the actions offered by the data source. It will be sent right after wl_data_device.enter, or anytime the source side changes its offered actions through wl_data_source.set_actions. This event indicates the action selected by the compositor after matching the source/destination side actions. Only one action (or none) will be offered here. This event can be emitted multiple times during the drag-and-drop operation in response to destination side action changes through wl_data_offer.set_actions. This event will no longer be emitted after wl_data_device.drop happened on the drag-and-drop destination, the client must honor the last action received, or the last preferred one set through wl_data_offer.set_actions when handling an "ask" action. Compositors may also change the selected action on the fly, mainly in response to keyboard modifier changes during the drag-and-drop operation. The most recent action received is always the valid one. Prior to receiving wl_data_device.drop, the chosen action may change (e.g. due to keyboard modifiers being pressed). At the time of receiving wl_data_device.drop the drag-and-drop destination must honor the last action received. Action changes may still happen after wl_data_device.drop, especially on "ask" actions, where the drag-and-drop destination may choose another action afterwards. Action changes happening at this stage are always the result of inter-client negotiation, the compositor shall no longer be able to induce a different action. Upon "ask" actions, it is expected that the drag-and-drop destination may potentially choose a different action and/or mime type, based on wl_data_offer.source_actions and finally chosen by the user (e.g. popping up a menu with the available options). The final wl_data_offer.set_actions and wl_data_offer.accept requests must happen before the call to wl_data_offer.finish. The wl_data_source object is the source side of a wl_data_offer. It is created by the source client in a data transfer and provides a way to describe the offered data and a way to respond to requests to transfer the data. This request adds a mime type to the set of mime types advertised to targets. Can be called several times to offer multiple types. Destroy the data source. Sent when a target accepts pointer_focus or motion events. If a target does not accept any of the offered types, type is NULL. Used for feedback during drag-and-drop. Request for data from the client. Send the data as the specified mime type over the passed file descriptor, then close it. This data source is no longer valid. There are several reasons why this could happen: - The data source has been replaced by another data source. - The drag-and-drop operation was performed, but the drop destination did not accept any of the mime types offered through wl_data_source.target. - The drag-and-drop operation was performed, but the drop destination did not select any of the actions present in the mask offered through wl_data_source.action. - The drag-and-drop operation was performed but didn't happen over a surface. - The compositor cancelled the drag-and-drop operation (e.g. compositor dependent timeouts to avoid stale drag-and-drop transfers). The client should clean up and destroy this data source. For objects of version 2 or older, wl_data_source.cancelled will only be emitted if the data source was replaced by another data source. Sets the actions that the source side client supports for this operation. This request may trigger wl_data_source.action and wl_data_offer.action events if the compositor needs to change the selected action. The dnd_actions argument must contain only values expressed in the wl_data_device_manager.dnd_actions enum, otherwise it will result in a protocol error. This request must be made once only, and can only be made on sources used in drag-and-drop, so it must be performed before wl_data_device.start_drag. Attempting to use the source other than for drag-and-drop will raise a protocol error. The user performed the drop action. This event does not indicate acceptance, wl_data_source.cancelled may still be emitted afterwards if the drop destination does not accept any mime type. However, this event might however not be received if the compositor cancelled the drag-and-drop operation before this event could happen. Note that the data_source may still be used in the future and should not be destroyed here. The drop destination finished interoperating with this data source, so the client is now free to destroy this data source and free all associated data. If the action used to perform the operation was "move", the source can now delete the transferred data. This event indicates the action selected by the compositor after matching the source/destination side actions. Only one action (or none) will be offered here. This event can be emitted multiple times during the drag-and-drop operation, mainly in response to destination side changes through wl_data_offer.set_actions, and as the data device enters/leaves surfaces. It is only possible to receive this event after wl_data_source.dnd_drop_performed if the drag-and-drop operation ended in an "ask" action, in which case the final wl_data_source.action event will happen immediately before wl_data_source.dnd_finished. Compositors may also change the selected action on the fly, mainly in response to keyboard modifier changes during the drag-and-drop operation. The most recent action received is always the valid one. The chosen action may change alongside negotiation (e.g. an "ask" action can turn into a "move" operation), so the effects of the final action must always be applied in wl_data_offer.dnd_finished. Clients can trigger cursor surface changes from this point, so they reflect the current action. There is one wl_data_device per seat which can be obtained from the global wl_data_device_manager singleton. A wl_data_device provides access to inter-client data transfer mechanisms such as copy-and-paste and drag-and-drop. This request asks the compositor to start a drag-and-drop operation on behalf of the client. The source argument is the data source that provides the data for the eventual data transfer. If source is NULL, enter, leave and motion events are sent only to the client that initiated the drag and the client is expected to handle the data passing internally. The origin surface is the surface where the drag originates and the client must have an active implicit grab that matches the serial. The icon surface is an optional (can be NULL) surface that provides an icon to be moved around with the cursor. Initially, the top-left corner of the icon surface is placed at the cursor hotspot, but subsequent wl_surface.attach request can move the relative position. Attach requests must be confirmed with wl_surface.commit as usual. The icon surface is given the role of a drag-and-drop icon. If the icon surface already has another role, it raises a protocol error. The current and pending input regions of the icon wl_surface are cleared, and wl_surface.set_input_region is ignored until the wl_surface is no longer used as the icon surface. When the use as an icon ends, the current and pending input regions become undefined, and the wl_surface is unmapped. This request asks the compositor to set the selection to the data from the source on behalf of the client. To unset the selection, set the source to NULL. The data_offer event introduces a new wl_data_offer object, which will subsequently be used in either the data_device.enter event (for drag-and-drop) or the data_device.selection event (for selections). Immediately following the data_device_data_offer event, the new data_offer object will send out data_offer.offer events to describe the mime types it offers. This event is sent when an active drag-and-drop pointer enters a surface owned by the client. The position of the pointer at enter time is provided by the x and y arguments, in surface-local coordinates. This event is sent when the drag-and-drop pointer leaves the surface and the session ends. The client must destroy the wl_data_offer introduced at enter time at this point. This event is sent when the drag-and-drop pointer moves within the currently focused surface. The new position of the pointer is provided by the x and y arguments, in surface-local coordinates. The event is sent when a drag-and-drop operation is ended because the implicit grab is removed. The drag-and-drop destination is expected to honor the last action received through wl_data_offer.action, if the resulting action is "copy" or "move", the destination can still perform wl_data_offer.receive requests, and is expected to end all transfers with a wl_data_offer.finish request. If the resulting action is "ask", the action will not be considered final. The drag-and-drop destination is expected to perform one last wl_data_offer.set_actions request, or wl_data_offer.destroy in order to cancel the operation. The selection event is sent out to notify the client of a new wl_data_offer for the selection for this device. The data_device.data_offer and the data_offer.offer events are sent out immediately before this event to introduce the data offer object. The selection event is sent to a client immediately before receiving keyboard focus and when a new selection is set while the client has keyboard focus. The data_offer is valid until a new data_offer or NULL is received or until the client loses keyboard focus. The client must destroy the previous selection data_offer, if any, upon receiving this event. This request destroys the data device. The wl_data_device_manager is a singleton global object that provides access to inter-client data transfer mechanisms such as copy-and-paste and drag-and-drop. These mechanisms are tied to a wl_seat and this interface lets a client get a wl_data_device corresponding to a wl_seat. Depending on the version bound, the objects created from the bound wl_data_device_manager object will have different requirements for functioning properly. See wl_data_source.set_actions, wl_data_offer.accept and wl_data_offer.finish for details. Create a new data source. Create a new data device for a given seat. This is a bitmask of the available/preferred actions in a drag-and-drop operation. In the compositor, the selected action is a result of matching the actions offered by the source and destination sides. "action" events with a "none" action will be sent to both source and destination if there is no match. All further checks will effectively happen on (source actions ∩ destination actions). In addition, compositors may also pick different actions in reaction to key modifiers being pressed. One common design that is used in major toolkits (and the behavior recommended for compositors) is: - If no modifiers are pressed, the first match (in bit order) will be used. - Pressing Shift selects "move", if enabled in the mask. - Pressing Control selects "copy", if enabled in the mask. Behavior beyond that is considered implementation-dependent. Compositors may for example bind other modifiers (like Alt/Meta) or drags initiated with other buttons than BTN_LEFT to specific actions (e.g. "ask"). This interface is implemented by servers that provide desktop-style user interfaces. It allows clients to associate a wl_shell_surface with a basic surface. Create a shell surface for an existing surface. This gives the wl_surface the role of a shell surface. If the wl_surface already has another role, it raises a protocol error. Only one shell surface can be associated with a given surface. An interface that may be implemented by a wl_surface, for implementations that provide a desktop-style user interface. It provides requests to treat surfaces like toplevel, fullscreen or popup windows, move, resize or maximize them, associate metadata like title and class, etc. On the server side the object is automatically destroyed when the related wl_surface is destroyed. On the client side, wl_shell_surface_destroy() must be called before destroying the wl_surface object. A client must respond to a ping event with a pong request or the client may be deemed unresponsive. Start a pointer-driven move of the surface. This request must be used in response to a button press event. The server may ignore move requests depending on the state of the surface (e.g. fullscreen or maximized). These values are used to indicate which edge of a surface is being dragged in a resize operation. The server may use this information to adapt its behavior, e.g. choose an appropriate cursor image. Start a pointer-driven resizing of the surface. This request must be used in response to a button press event. The server may ignore resize requests depending on the state of the surface (e.g. fullscreen or maximized). Map the surface as a toplevel surface. A toplevel surface is not fullscreen, maximized or transient. These flags specify details of the expected behaviour of transient surfaces. Used in the set_transient request. Map the surface relative to an existing surface. The x and y arguments specify the location of the upper left corner of the surface relative to the upper left corner of the parent surface, in surface-local coordinates. The flags argument controls details of the transient behaviour. Hints to indicate to the compositor how to deal with a conflict between the dimensions of the surface and the dimensions of the output. The compositor is free to ignore this parameter. Map the surface as a fullscreen surface. If an output parameter is given then the surface will be made fullscreen on that output. If the client does not specify the output then the compositor will apply its policy - usually choosing the output on which the surface has the biggest surface area. The client may specify a method to resolve a size conflict between the output size and the surface size - this is provided through the method parameter. The framerate parameter is used only when the method is set to "driver", to indicate the preferred framerate. A value of 0 indicates that the client does not care about framerate. The framerate is specified in mHz, that is framerate of 60000 is 60Hz. A method of "scale" or "driver" implies a scaling operation of the surface, either via a direct scaling operation or a change of the output mode. This will override any kind of output scaling, so that mapping a surface with a buffer size equal to the mode can fill the screen independent of buffer_scale. A method of "fill" means we don't scale up the buffer, however any output scale is applied. This means that you may run into an edge case where the application maps a buffer with the same size of the output mode but buffer_scale 1 (thus making a surface larger than the output). In this case it is allowed to downscale the results to fit the screen. The compositor must reply to this request with a configure event with the dimensions for the output on which the surface will be made fullscreen. Map the surface as a popup. A popup surface is a transient surface with an added pointer grab. An existing implicit grab will be changed to owner-events mode, and the popup grab will continue after the implicit grab ends (i.e. releasing the mouse button does not cause the popup to be unmapped). The popup grab continues until the window is destroyed or a mouse button is pressed in any other client's window. A click in any of the client's surfaces is reported as normal, however, clicks in other clients' surfaces will be discarded and trigger the callback. The x and y arguments specify the location of the upper left corner of the surface relative to the upper left corner of the parent surface, in surface-local coordinates. Map the surface as a maximized surface. If an output parameter is given then the surface will be maximized on that output. If the client does not specify the output then the compositor will apply its policy - usually choosing the output on which the surface has the biggest surface area. The compositor will reply with a configure event telling the expected new surface size. The operation is completed on the next buffer attach to this surface. A maximized surface typically fills the entire output it is bound to, except for desktop elements such as panels. This is the main difference between a maximized shell surface and a fullscreen shell surface. The details depend on the compositor implementation. Set a short title for the surface. This string may be used to identify the surface in a task bar, window list, or other user interface elements provided by the compositor. The string must be encoded in UTF-8. Set a class for the surface. The surface class identifies the general class of applications to which the surface belongs. A common convention is to use the file name (or the full path if it is a non-standard location) of the application's .desktop file as the class. Ping a client to check if it is receiving events and sending requests. A client is expected to reply with a pong request. The configure event asks the client to resize its surface. The size is a hint, in the sense that the client is free to ignore it if it doesn't resize, pick a smaller size (to satisfy aspect ratio or resize in steps of NxM pixels). The edges parameter provides a hint about how the surface was resized. The client may use this information to decide how to adjust its content to the new size (e.g. a scrolling area might adjust its content position to leave the viewable content unmoved). The client is free to dismiss all but the last configure event it received. The width and height arguments specify the size of the window in surface-local coordinates. The popup_done event is sent out when a popup grab is broken, that is, when the user clicks a surface that doesn't belong to the client owning the popup surface. A surface is a rectangular area that is displayed on the screen. It has a location, size and pixel contents. The size of a surface (and relative positions on it) is described in surface-local coordinates, which may differ from the buffer coordinates of the pixel content, in case a buffer_transform or a buffer_scale is used. A surface without a "role" is fairly useless: a compositor does not know where, when or how to present it. The role is the purpose of a wl_surface. Examples of roles are a cursor for a pointer (as set by wl_pointer.set_cursor), a drag icon (wl_data_device.start_drag), a sub-surface (wl_subcompositor.get_subsurface), and a window as defined by a shell protocol (e.g. wl_shell.get_shell_surface). A surface can have only one role at a time. Initially a wl_surface does not have a role. Once a wl_surface is given a role, it is set permanently for the whole lifetime of the wl_surface object. Giving the current role again is allowed, unless explicitly forbidden by the relevant interface specification. Surface roles are given by requests in other interfaces such as wl_pointer.set_cursor. The request should explicitly mention that this request gives a role to a wl_surface. Often, this request also creates a new protocol object that represents the role and adds additional functionality to wl_surface. When a client wants to destroy a wl_surface, they must destroy this 'role object' before the wl_surface. Destroying the role object does not remove the role from the wl_surface, but it may stop the wl_surface from "playing the role". For instance, if a wl_subsurface object is destroyed, the wl_surface it was created for will be unmapped and forget its position and z-order. It is allowed to create a wl_subsurface for the same wl_surface again, but it is not allowed to use the wl_surface as a cursor (cursor is a different role than sub-surface, and role switching is not allowed). These errors can be emitted in response to wl_surface requests. Deletes the surface and invalidates its object ID. Set a buffer as the content of this surface. The new size of the surface is calculated based on the buffer size transformed by the inverse buffer_transform and the inverse buffer_scale. This means that the supplied buffer must be an integer multiple of the buffer_scale. The x and y arguments specify the location of the new pending buffer's upper left corner, relative to the current buffer's upper left corner, in surface-local coordinates. In other words, the x and y, combined with the new surface size define in which directions the surface's size changes. Surface contents are double-buffered state, see wl_surface.commit. The initial surface contents are void; there is no content. wl_surface.attach assigns the given wl_buffer as the pending wl_buffer. wl_surface.commit makes the pending wl_buffer the new surface contents, and the size of the surface becomes the size calculated from the wl_buffer, as described above. After commit, there is no pending buffer until the next attach. Committing a pending wl_buffer allows the compositor to read the pixels in the wl_buffer. The compositor may access the pixels at any time after the wl_surface.commit request. When the compositor will not access the pixels anymore, it will send the wl_buffer.release event. Only after receiving wl_buffer.release, the client may reuse the wl_buffer. A wl_buffer that has been attached and then replaced by another attach instead of committed will not receive a release event, and is not used by the compositor. Destroying the wl_buffer after wl_buffer.release does not change the surface contents. However, if the client destroys the wl_buffer before receiving the wl_buffer.release event, the surface contents become undefined immediately. If wl_surface.attach is sent with a NULL wl_buffer, the following wl_surface.commit will remove the surface content. This request is used to describe the regions where the pending buffer is different from the current surface contents, and where the surface therefore needs to be repainted. The compositor ignores the parts of the damage that fall outside of the surface. Damage is double-buffered state, see wl_surface.commit. The damage rectangle is specified in surface-local coordinates, where x and y specify the upper left corner of the damage rectangle. The initial value for pending damage is empty: no damage. wl_surface.damage adds pending damage: the new pending damage is the union of old pending damage and the given rectangle. wl_surface.commit assigns pending damage as the current damage, and clears pending damage. The server will clear the current damage as it repaints the surface. Alternatively, damage can be posted with wl_surface.damage_buffer which uses buffer coordinates instead of surface coordinates, and is probably the preferred and intuitive way of doing this. Request a notification when it is a good time to start drawing a new frame, by creating a frame callback. This is useful for throttling redrawing operations, and driving animations. When a client is animating on a wl_surface, it can use the 'frame' request to get notified when it is a good time to draw and commit the next frame of animation. If the client commits an update earlier than that, it is likely that some updates will not make it to the display, and the client is wasting resources by drawing too often. The frame request will take effect on the next wl_surface.commit. The notification will only be posted for one frame unless requested again. For a wl_surface, the notifications are posted in the order the frame requests were committed. The server must send the notifications so that a client will not send excessive updates, while still allowing the highest possible update rate for clients that wait for the reply before drawing again. The server should give some time for the client to draw and commit after sending the frame callback events to let it hit the next output refresh. A server should avoid signaling the frame callbacks if the surface is not visible in any way, e.g. the surface is off-screen, or completely obscured by other opaque surfaces. The object returned by this request will be destroyed by the compositor after the callback is fired and as such the client must not attempt to use it after that point. The callback_data passed in the callback is the current time, in milliseconds, with an undefined base. This request sets the region of the surface that contains opaque content. The opaque region is an optimization hint for the compositor that lets it optimize the redrawing of content behind opaque regions. Setting an opaque region is not required for correct behaviour, but marking transparent content as opaque will result in repaint artifacts. The opaque region is specified in surface-local coordinates. The compositor ignores the parts of the opaque region that fall outside of the surface. Opaque region is double-buffered state, see wl_surface.commit. wl_surface.set_opaque_region changes the pending opaque region. wl_surface.commit copies the pending region to the current region. Otherwise, the pending and current regions are never changed. The initial value for an opaque region is empty. Setting the pending opaque region has copy semantics, and the wl_region object can be destroyed immediately. A NULL wl_region causes the pending opaque region to be set to empty. This request sets the region of the surface that can receive pointer and touch events. Input events happening outside of this region will try the next surface in the server surface stack. The compositor ignores the parts of the input region that fall outside of the surface. The input region is specified in surface-local coordinates. Input region is double-buffered state, see wl_surface.commit. wl_surface.set_input_region changes the pending input region. wl_surface.commit copies the pending region to the current region. Otherwise the pending and current regions are never changed, except cursor and icon surfaces are special cases, see wl_pointer.set_cursor and wl_data_device.start_drag. The initial value for an input region is infinite. That means the whole surface will accept input. Setting the pending input region has copy semantics, and the wl_region object can be destroyed immediately. A NULL wl_region causes the input region to be set to infinite. Surface state (input, opaque, and damage regions, attached buffers, etc.) is double-buffered. Protocol requests modify the pending state, as opposed to the current state in use by the compositor. A commit request atomically applies all pending state, replacing the current state. After commit, the new pending state is as documented for each related request. On commit, a pending wl_buffer is applied first, and all other state second. This means that all coordinates in double-buffered state are relative to the new wl_buffer coming into use, except for wl_surface.attach itself. If there is no pending wl_buffer, the coordinates are relative to the current surface contents. All requests that need a commit to become effective are documented to affect double-buffered state. Other interfaces may add further double-buffered surface state. This is emitted whenever a surface's creation, movement, or resizing results in some part of it being within the scanout region of an output. Note that a surface may be overlapping with zero or more outputs. This is emitted whenever a surface's creation, movement, or resizing results in it no longer having any part of it within the scanout region of an output. This request sets an optional transformation on how the compositor interprets the contents of the buffer attached to the surface. The accepted values for the transform parameter are the values for wl_output.transform. Buffer transform is double-buffered state, see wl_surface.commit. A newly created surface has its buffer transformation set to normal. wl_surface.set_buffer_transform changes the pending buffer transformation. wl_surface.commit copies the pending buffer transformation to the current one. Otherwise, the pending and current values are never changed. The purpose of this request is to allow clients to render content according to the output transform, thus permitting the compositor to use certain optimizations even if the display is rotated. Using hardware overlays and scanning out a client buffer for fullscreen surfaces are examples of such optimizations. Those optimizations are highly dependent on the compositor implementation, so the use of this request should be considered on a case-by-case basis. Note that if the transform value includes 90 or 270 degree rotation, the width of the buffer will become the surface height and the height of the buffer will become the surface width. If transform is not one of the values from the wl_output.transform enum the invalid_transform protocol error is raised. This request sets an optional scaling factor on how the compositor interprets the contents of the buffer attached to the window. Buffer scale is double-buffered state, see wl_surface.commit. A newly created surface has its buffer scale set to 1. wl_surface.set_buffer_scale changes the pending buffer scale. wl_surface.commit copies the pending buffer scale to the current one. Otherwise, the pending and current values are never changed. The purpose of this request is to allow clients to supply higher resolution buffer data for use on high resolution outputs. It is intended that you pick the same buffer scale as the scale of the output that the surface is displayed on. This means the compositor can avoid scaling when rendering the surface on that output. Note that if the scale is larger than 1, then you have to attach a buffer that is larger (by a factor of scale in each dimension) than the desired surface size. If scale is not positive the invalid_scale protocol error is raised. This request is used to describe the regions where the pending buffer is different from the current surface contents, and where the surface therefore needs to be repainted. The compositor ignores the parts of the damage that fall outside of the surface. Damage is double-buffered state, see wl_surface.commit. The damage rectangle is specified in buffer coordinates, where x and y specify the upper left corner of the damage rectangle. The initial value for pending damage is empty: no damage. wl_surface.damage_buffer adds pending damage: the new pending damage is the union of old pending damage and the given rectangle. wl_surface.commit assigns pending damage as the current damage, and clears pending damage. The server will clear the current damage as it repaints the surface. This request differs from wl_surface.damage in only one way - it takes damage in buffer coordinates instead of surface-local coordinates. While this generally is more intuitive than surface coordinates, it is especially desirable when using wp_viewport or when a drawing library (like EGL) is unaware of buffer scale and buffer transform. Note: Because buffer transformation changes and damage requests may be interleaved in the protocol stream, it is impossible to determine the actual mapping between surface and buffer damage until wl_surface.commit time. Therefore, compositors wishing to take both kinds of damage into account will have to accumulate damage from the two requests separately and only transform from one to the other after receiving the wl_surface.commit. A seat is a group of keyboards, pointer and touch devices. This object is published as a global during start up, or when such a device is hot plugged. A seat typically has a pointer and maintains a keyboard focus and a pointer focus. This is a bitmask of capabilities this seat has; if a member is set, then it is present on the seat. This is emitted whenever a seat gains or loses the pointer, keyboard or touch capabilities. The argument is a capability enum containing the complete set of capabilities this seat has. When the pointer capability is added, a client may create a wl_pointer object using the wl_seat.get_pointer request. This object will receive pointer events until the capability is removed in the future. When the pointer capability is removed, a client should destroy the wl_pointer objects associated with the seat where the capability was removed, using the wl_pointer.release request. No further pointer events will be received on these objects. In some compositors, if a seat regains the pointer capability and a client has a previously obtained wl_pointer object of version 4 or less, that object may start sending pointer events again. This behavior is considered a misinterpretation of the intended behavior and must not be relied upon by the client. wl_pointer objects of version 5 or later must not send events if created before the most recent event notifying the client of an added pointer capability. The above behavior also applies to wl_keyboard and wl_touch with the keyboard and touch capabilities, respectively. The ID provided will be initialized to the wl_pointer interface for this seat. This request only takes effect if the seat has the pointer capability, or has had the pointer capability in the past. It is a protocol violation to issue this request on a seat that has never had the pointer capability. The ID provided will be initialized to the wl_keyboard interface for this seat. This request only takes effect if the seat has the keyboard capability, or has had the keyboard capability in the past. It is a protocol violation to issue this request on a seat that has never had the keyboard capability. The ID provided will be initialized to the wl_touch interface for this seat. This request only takes effect if the seat has the touch capability, or has had the touch capability in the past. It is a protocol violation to issue this request on a seat that has never had the touch capability. In a multiseat configuration this can be used by the client to help identify which physical devices the seat represents. Based on the seat configuration used by the compositor. Using this request a client can tell the server that it is not going to use the seat object anymore. The wl_pointer interface represents one or more input devices, such as mice, which control the pointer location and pointer_focus of a seat. The wl_pointer interface generates motion, enter and leave events for the surfaces that the pointer is located over, and button and axis events for button presses, button releases and scrolling. Set the pointer surface, i.e., the surface that contains the pointer image (cursor). This request gives the surface the role of a cursor. If the surface already has another role, it raises a protocol error. The cursor actually changes only if the pointer focus for this device is one of the requesting client's surfaces or the surface parameter is the current pointer surface. If there was a previous surface set with this request it is replaced. If surface is NULL, the pointer image is hidden. The parameters hotspot_x and hotspot_y define the position of the pointer surface relative to the pointer location. Its top-left corner is always at (x, y) - (hotspot_x, hotspot_y), where (x, y) are the coordinates of the pointer location, in surface-local coordinates. On surface.attach requests to the pointer surface, hotspot_x and hotspot_y are decremented by the x and y parameters passed to the request. Attach must be confirmed by wl_surface.commit as usual. The hotspot can also be updated by passing the currently set pointer surface to this request with new values for hotspot_x and hotspot_y. The current and pending input regions of the wl_surface are cleared, and wl_surface.set_input_region is ignored until the wl_surface is no longer used as the cursor. When the use as a cursor ends, the current and pending input regions become undefined, and the wl_surface is unmapped. Notification that this seat's pointer is focused on a certain surface. When a seat's focus enters a surface, the pointer image is undefined and a client should respond to this event by setting an appropriate pointer image with the set_cursor request. Notification that this seat's pointer is no longer focused on a certain surface. The leave notification is sent before the enter notification for the new focus. Notification of pointer location change. The arguments surface_x and surface_y are the location relative to the focused surface. Describes the physical state of a button that produced the button event. Mouse button click and release notifications. The location of the click is given by the last motion or enter event. The time argument is a timestamp with millisecond granularity, with an undefined base. The button is a button code as defined in the Linux kernel's linux/input-event-codes.h header file, e.g. BTN_LEFT. Any 16-bit button code value is reserved for future additions to the kernel's event code list. All other button codes above 0xFFFF are currently undefined but may be used in future versions of this protocol. Describes the axis types of scroll events. Scroll and other axis notifications. For scroll events (vertical and horizontal scroll axes), the value parameter is the length of a vector along the specified axis in a coordinate space identical to those of motion events, representing a relative movement along the specified axis. For devices that support movements non-parallel to axes multiple axis events will be emitted. When applicable, for example for touch pads, the server can choose to emit scroll events where the motion vector is equivalent to a motion event vector. When applicable, a client can transform its content relative to the scroll distance. Using this request a client can tell the server that it is not going to use the pointer object anymore. This request destroys the pointer proxy object, so clients must not call wl_pointer_destroy() after using this request. Indicates the end of a set of events that logically belong together. A client is expected to accumulate the data in all events within the frame before proceeding. All wl_pointer events before a wl_pointer.frame event belong logically together. For example, in a diagonal scroll motion the compositor will send an optional wl_pointer.axis_source event, two wl_pointer.axis events (horizontal and vertical) and finally a wl_pointer.frame event. The client may use this information to calculate a diagonal vector for scrolling. When multiple wl_pointer.axis events occur within the same frame, the motion vector is the combined motion of all events. When a wl_pointer.axis and a wl_pointer.axis_stop event occur within the same frame, this indicates that axis movement in one axis has stopped but continues in the other axis. When multiple wl_pointer.axis_stop events occur within the same frame, this indicates that these axes stopped in the same instance. A wl_pointer.frame event is sent for every logical event group, even if the group only contains a single wl_pointer event. Specifically, a client may get a sequence: motion, frame, button, frame, axis, frame, axis_stop, frame. The wl_pointer.enter and wl_pointer.leave events are logical events generated by the compositor and not the hardware. These events are also grouped by a wl_pointer.frame. When a pointer moves from one surface to another, a compositor should group the wl_pointer.leave event within the same wl_pointer.frame. However, a client must not rely on wl_pointer.leave and wl_pointer.enter being in the same wl_pointer.frame. Compositor-specific policies may require the wl_pointer.leave and wl_pointer.enter event being split across multiple wl_pointer.frame groups. Describes the source types for axis events. This indicates to the client how an axis event was physically generated; a client may adjust the user interface accordingly. For example, scroll events from a "finger" source may be in a smooth coordinate space with kinetic scrolling whereas a "wheel" source may be in discrete steps of a number of lines. The "continuous" axis source is a device generating events in a continuous coordinate space, but using something other than a finger. One example for this source is button-based scrolling where the vertical motion of a device is converted to scroll events while a button is held down. The "wheel tilt" axis source indicates that the actual device is a wheel but the scroll event is not caused by a rotation but a (usually sideways) tilt of the wheel. Source information for scroll and other axes. This event does not occur on its own. It is sent before a wl_pointer.frame event and carries the source information for all events within that frame. The source specifies how this event was generated. If the source is wl_pointer.axis_source.finger, a wl_pointer.axis_stop event will be sent when the user lifts the finger off the device. If the source is wl_pointer.axis_source.wheel, wl_pointer.axis_source.wheel_tilt or wl_pointer.axis_source.continuous, a wl_pointer.axis_stop event may or may not be sent. Whether a compositor sends an axis_stop event for these sources is hardware-specific and implementation-dependent; clients must not rely on receiving an axis_stop event for these scroll sources and should treat scroll sequences from these scroll sources as unterminated by default. This event is optional. If the source is unknown for a particular axis event sequence, no event is sent. Only one wl_pointer.axis_source event is permitted per frame. The order of wl_pointer.axis_discrete and wl_pointer.axis_source is not guaranteed. Stop notification for scroll and other axes. For some wl_pointer.axis_source types, a wl_pointer.axis_stop event is sent to notify a client that the axis sequence has terminated. This enables the client to implement kinetic scrolling. See the wl_pointer.axis_source documentation for information on when this event may be generated. Any wl_pointer.axis events with the same axis_source after this event should be considered as the start of a new axis motion. The timestamp is to be interpreted identical to the timestamp in the wl_pointer.axis event. The timestamp value may be the same as a preceding wl_pointer.axis event. Discrete step information for scroll and other axes. This event carries the axis value of the wl_pointer.axis event in discrete steps (e.g. mouse wheel clicks). This event does not occur on its own, it is coupled with a wl_pointer.axis event that represents this axis value on a continuous scale. The protocol guarantees that each axis_discrete event is always followed by exactly one axis event with the same axis number within the same wl_pointer.frame. Note that the protocol allows for other events to occur between the axis_discrete and its coupled axis event, including other axis_discrete or axis events. This event is optional; continuous scrolling devices like two-finger scrolling on touchpads do not have discrete steps and do not generate this event. The discrete value carries the directional information. e.g. a value of -2 is two steps towards the negative direction of this axis. The axis number is identical to the axis number in the associated axis event. The order of wl_pointer.axis_discrete and wl_pointer.axis_source is not guaranteed. The wl_keyboard interface represents one or more keyboards associated with a seat. This specifies the format of the keymap provided to the client with the wl_keyboard.keymap event. This event provides a file descriptor to the client which can be memory-mapped to provide a keyboard mapping description. Notification that this seat's keyboard focus is on a certain surface. Notification that this seat's keyboard focus is no longer on a certain surface. The leave notification is sent before the enter notification for the new focus. Describes the physical state of a key that produced the key event. A key was pressed or released. The time argument is a timestamp with millisecond granularity, with an undefined base. Notifies clients that the modifier and/or group state has changed, and it should update its local state. Informs the client about the keyboard's repeat rate and delay. This event is sent as soon as the wl_keyboard object has been created, and is guaranteed to be received by the client before any key press event. Negative values for either rate or delay are illegal. A rate of zero will disable any repeating (regardless of the value of delay). This event can be sent later on as well with a new value if necessary, so clients should continue listening for the event past the creation of wl_keyboard. The wl_touch interface represents a touchscreen associated with a seat. Touch interactions can consist of one or more contacts. For each contact, a series of events is generated, starting with a down event, followed by zero or more motion events, and ending with an up event. Events relating to the same contact point can be identified by the ID of the sequence. A new touch point has appeared on the surface. This touch point is assigned a unique ID. Future events from this touch point reference this ID. The ID ceases to be valid after a touch up event and may be reused in the future. The touch point has disappeared. No further events will be sent for this touch point and the touch point's ID is released and may be reused in a future touch down event. A touch point has changed coordinates. Indicates the end of a set of events that logically belong together. A client is expected to accumulate the data in all events within the frame before proceeding. A wl_touch.frame terminates at least one event but otherwise no guarantee is provided about the set of events within a frame. A client must assume that any state not updated in a frame is unchanged from the previously known state. Sent if the compositor decides the touch stream is a global gesture. No further events are sent to the clients from that particular gesture. Touch cancellation applies to all touch points currently active on this client's surface. The client is responsible for finalizing the touch points, future touch points on this surface may reuse the touch point ID. Sent when a touchpoint has changed its shape. This event does not occur on its own. It is sent before a wl_touch.frame event and carries the new shape information for any previously reported, or new touch points of that frame. Other events describing the touch point such as wl_touch.down, wl_touch.motion or wl_touch.orientation may be sent within the same wl_touch.frame. A client should treat these events as a single logical touch point update. The order of wl_touch.shape, wl_touch.orientation and wl_touch.motion is not guaranteed. A wl_touch.down event is guaranteed to occur before the first wl_touch.shape event for this touch ID but both events may occur within the same wl_touch.frame. A touchpoint shape is approximated by an ellipse through the major and minor axis length. The major axis length describes the longer diameter of the ellipse, while the minor axis length describes the shorter diameter. Major and minor are orthogonal and both are specified in surface-local coordinates. The center of the ellipse is always at the touchpoint location as reported by wl_touch.down or wl_touch.move. This event is only sent by the compositor if the touch device supports shape reports. The client has to make reasonable assumptions about the shape if it did not receive this event. Sent when a touchpoint has changed its orientation. This event does not occur on its own. It is sent before a wl_touch.frame event and carries the new shape information for any previously reported, or new touch points of that frame. Other events describing the touch point such as wl_touch.down, wl_touch.motion or wl_touch.shape may be sent within the same wl_touch.frame. A client should treat these events as a single logical touch point update. The order of wl_touch.shape, wl_touch.orientation and wl_touch.motion is not guaranteed. A wl_touch.down event is guaranteed to occur before the first wl_touch.orientation event for this touch ID but both events may occur within the same wl_touch.frame. The orientation describes the clockwise angle of a touchpoint's major axis to the positive surface y-axis and is normalized to the -180 to +180 degree range. The granularity of orientation depends on the touch device, some devices only support binary rotation values between 0 and 90 degrees. This event is only sent by the compositor if the touch device supports orientation reports. An output describes part of the compositor geometry. The compositor works in the 'compositor coordinate system' and an output corresponds to a rectangular area in that space that is actually visible. This typically corresponds to a monitor that displays part of the compositor space. This object is published as global during start up, or when a monitor is hotplugged. This enumeration describes how the physical pixels on an output are laid out. This describes the transform that a compositor will apply to a surface to compensate for the rotation or mirroring of an output device. The flipped values correspond to an initial flip around a vertical axis followed by rotation. The purpose is mainly to allow clients to render accordingly and tell the compositor, so that for fullscreen surfaces, the compositor will still be able to scan out directly from client surfaces. The geometry event describes geometric properties of the output. The event is sent when binding to the output object and whenever any of the properties change. These flags describe properties of an output mode. They are used in the flags bitfield of the mode event. The mode event describes an available mode for the output. The event is sent when binding to the output object and there will always be one mode, the current mode. The event is sent again if an output changes mode, for the mode that is now current. In other words, the current mode is always the last mode that was received with the current flag set. The size of a mode is given in physical hardware units of the output device. This is not necessarily the same as the output size in the global compositor space. For instance, the output may be scaled, as described in wl_output.scale, or transformed, as described in wl_output.transform. This event is sent after all other properties have been sent after binding to the output object and after any other property changes done after that. This allows changes to the output properties to be seen as atomic, even if they happen via multiple events. This event contains scaling geometry information that is not in the geometry event. It may be sent after binding the output object or if the output scale changes later. If it is not sent, the client should assume a scale of 1. A scale larger than 1 means that the compositor will automatically scale surface buffers by this amount when rendering. This is used for very high resolution displays where applications rendering at the native resolution would be too small to be legible. It is intended that scaling aware clients track the current output of a surface, and if it is on a scaled output it should use wl_surface.set_buffer_scale with the scale of the output. That way the compositor can avoid scaling the surface, and the client can supply a higher detail image. Using this request a client can tell the server that it is not going to use the output object anymore. A region object describes an area. Region objects are used to describe the opaque and input regions of a surface. Destroy the region. This will invalidate the object ID. Add the specified rectangle to the region. Subtract the specified rectangle from the region. The global interface exposing sub-surface compositing capabilities. A wl_surface, that has sub-surfaces associated, is called the parent surface. Sub-surfaces can be arbitrarily nested and create a tree of sub-surfaces. The root surface in a tree of sub-surfaces is the main surface. The main surface cannot be a sub-surface, because sub-surfaces must always have a parent. A main surface with its sub-surfaces forms a (compound) window. For window management purposes, this set of wl_surface objects is to be considered as a single window, and it should also behave as such. The aim of sub-surfaces is to offload some of the compositing work within a window from clients to the compositor. A prime example is a video player with decorations and video in separate wl_surface objects. This should allow the compositor to pass YUV video buffer processing to dedicated overlay hardware when possible. Informs the server that the client will not be using this protocol object anymore. This does not affect any other objects, wl_subsurface objects included. Create a sub-surface interface for the given surface, and associate it with the given parent surface. This turns a plain wl_surface into a sub-surface. The to-be sub-surface must not already have another role, and it must not have an existing wl_subsurface object. Otherwise a protocol error is raised. An additional interface to a wl_surface object, which has been made a sub-surface. A sub-surface has one parent surface. A sub-surface's size and position are not limited to that of the parent. Particularly, a sub-surface is not automatically clipped to its parent's area. A sub-surface becomes mapped, when a non-NULL wl_buffer is applied and the parent surface is mapped. The order of which one happens first is irrelevant. A sub-surface is hidden if the parent becomes hidden, or if a NULL wl_buffer is applied. These rules apply recursively through the tree of surfaces. The behaviour of a wl_surface.commit request on a sub-surface depends on the sub-surface's mode. The possible modes are synchronized and desynchronized, see methods wl_subsurface.set_sync and wl_subsurface.set_desync. Synchronized mode caches the wl_surface state to be applied when the parent's state gets applied, and desynchronized mode applies the pending wl_surface state directly. A sub-surface is initially in the synchronized mode. Sub-surfaces have also other kind of state, which is managed by wl_subsurface requests, as opposed to wl_surface requests. This state includes the sub-surface position relative to the parent surface (wl_subsurface.set_position), and the stacking order of the parent and its sub-surfaces (wl_subsurface.place_above and .place_below). This state is applied when the parent surface's wl_surface state is applied, regardless of the sub-surface's mode. As the exception, set_sync and set_desync are effective immediately. The main surface can be thought to be always in desynchronized mode, since it does not have a parent in the sub-surfaces sense. Even if a sub-surface is in desynchronized mode, it will behave as in synchronized mode, if its parent surface behaves as in synchronized mode. This rule is applied recursively throughout the tree of surfaces. This means, that one can set a sub-surface into synchronized mode, and then assume that all its child and grand-child sub-surfaces are synchronized, too, without explicitly setting them. If the wl_surface associated with the wl_subsurface is destroyed, the wl_subsurface object becomes inert. Note, that destroying either object takes effect immediately. If you need to synchronize the removal of a sub-surface to the parent surface update, unmap the sub-surface first by attaching a NULL wl_buffer, update parent, and then destroy the sub-surface. If the parent wl_surface object is destroyed, the sub-surface is unmapped. The sub-surface interface is removed from the wl_surface object that was turned into a sub-surface with a wl_subcompositor.get_subsurface request. The wl_surface's association to the parent is deleted, and the wl_surface loses its role as a sub-surface. The wl_surface is unmapped. This schedules a sub-surface position change. The sub-surface will be moved so that its origin (top left corner pixel) will be at the location x, y of the parent surface coordinate system. The coordinates are not restricted to the parent surface area. Negative values are allowed. The scheduled coordinates will take effect whenever the state of the parent surface is applied. When this happens depends on whether the parent surface is in synchronized mode or not. See wl_subsurface.set_sync and wl_subsurface.set_desync for details. If more than one set_position request is invoked by the client before the commit of the parent surface, the position of a new request always replaces the scheduled position from any previous request. The initial position is 0, 0. This sub-surface is taken from the stack, and put back just above the reference surface, changing the z-order of the sub-surfaces. The reference surface must be one of the sibling surfaces, or the parent surface. Using any other surface, including this sub-surface, will cause a protocol error. The z-order is double-buffered. Requests are handled in order and applied immediately to a pending state. The final pending state is copied to the active state the next time the state of the parent surface is applied. When this happens depends on whether the parent surface is in synchronized mode or not. See wl_subsurface.set_sync and wl_subsurface.set_desync for details. A new sub-surface is initially added as the top-most in the stack of its siblings and parent. The sub-surface is placed just below the reference surface. See wl_subsurface.place_above. Change the commit behaviour of the sub-surface to synchronized mode, also described as the parent dependent mode. In synchronized mode, wl_surface.commit on a sub-surface will accumulate the committed state in a cache, but the state will not be applied and hence will not change the compositor output. The cached state is applied to the sub-surface immediately after the parent surface's state is applied. This ensures atomic updates of the parent and all its synchronized sub-surfaces. Applying the cached state will invalidate the cache, so further parent surface commits do not (re-)apply old state. See wl_subsurface for the recursive effect of this mode. Change the commit behaviour of the sub-surface to desynchronized mode, also described as independent or freely running mode. In desynchronized mode, wl_surface.commit on a sub-surface will apply the pending state directly, without caching, as happens normally with a wl_surface. Calling wl_surface.commit on the parent surface has no effect on the sub-surface's wl_surface state. This mode allows a sub-surface to be updated on its own. If cached state exists when wl_surface.commit is called in desynchronized mode, the pending state is added to the cached state, and applied as a whole. This invalidates the cache. Note: even if a sub-surface is set to desynchronized, a parent sub-surface may override it to behave as synchronized. For details, see wl_subsurface. If a surface's parent surface behaves as desynchronized, then the cached state is applied on set_desync. wayland-1.18.0/tests/data/bad-identifier-protocol.xml0000644000175000017500000000037013620636273021610 0ustar zumbizumbi wayland-1.18.0/tests/data/bad-identifier-interface.xml0000644000175000017500000000034613620636273021712 0ustar zumbizumbi wayland-1.18.0/tests/data/example-server.h0000644000175000017500000041713713620636273017506 0ustar zumbizumbi/* SCANNER TEST */ #ifndef WAYLAND_SERVER_PROTOCOL_H #define WAYLAND_SERVER_PROTOCOL_H #include #include #include "wayland-server.h" #ifdef __cplusplus extern "C" { #endif struct wl_client; struct wl_resource; /** * @page page_wayland The wayland protocol * @section page_ifaces_wayland Interfaces * - @subpage page_iface_wl_display - core global object * - @subpage page_iface_wl_registry - global registry object * - @subpage page_iface_wl_callback - callback object * - @subpage page_iface_wl_compositor - the compositor singleton * - @subpage page_iface_wl_shm_pool - a shared memory pool * - @subpage page_iface_wl_shm - shared memory support * - @subpage page_iface_wl_buffer - content for a wl_surface * - @subpage page_iface_wl_data_offer - offer to transfer data * - @subpage page_iface_wl_data_source - offer to transfer data * - @subpage page_iface_wl_data_device - data transfer device * - @subpage page_iface_wl_data_device_manager - data transfer interface * - @subpage page_iface_wl_shell - create desktop-style surfaces * - @subpage page_iface_wl_shell_surface - desktop-style metadata interface * - @subpage page_iface_wl_surface - an onscreen surface * - @subpage page_iface_wl_seat - group of input devices * - @subpage page_iface_wl_pointer - pointer input device * - @subpage page_iface_wl_keyboard - keyboard input device * - @subpage page_iface_wl_touch - touchscreen input device * - @subpage page_iface_wl_output - compositor output region * - @subpage page_iface_wl_region - region interface * - @subpage page_iface_wl_subcompositor - sub-surface compositing * - @subpage page_iface_wl_subsurface - sub-surface interface to a wl_surface * @section page_copyright_wayland Copyright *
