+ <description summary="protocol for constraining pointer motions">
+ This protocol specifies a set of interfaces used for adding constraints to
+ the motion of a pointer. Possible constraints include confining pointer
+ motions to a given region, or locking it to its current position.
+
+ In order to constrain the pointer, a client must first bind the global
+ interface "wp_pointer_constraints" which, if a compositor supports pointer
+ constraints, is exposed by the registry. Using the bound global object, the
+ client uses the request that corresponds to the type of constraint it wants
+ to make. See wp_pointer_constraints for more details.
+
+ Warning! The protocol described in this file is experimental and backward
+ incompatible changes may be made. Backward compatible changes may be added
+ together with the corresponding interface version bump. Backward
+ incompatible changes are done by bumping the version number in the protocol
+ and interface names and resetting the interface version. Once the protocol
+ is to be declared stable, the 'z' prefix and the version number in the
+ protocol and interface names are removed and the interface version number is

+ <description summary="constrain the movement of a pointer">
+ The global interface exposing pointer constraining functionality. It
+ exposes two requests: lock_pointer for locking the pointer to its
+ position, and confine_pointer for locking the pointer to a region.
+
+ The lock_pointer and confine_pointer requests create the objects
+ wp_locked_pointer and wp_confined_pointer respectively, and the client can
+ use these objects to interact with the lock.
+
+ For any surface, only one lock or confinement may be active across all
+ wl_pointer objects of the same seat. If a lock or confinement is requested
+ when another lock or confinement is active or requested on the same surface

+ <description summary="lock pointer to a position">
+ The lock_pointer request lets the client request to disable movements of
+ the virtual pointer (i.e. the cursor), effectively locking the pointer
+ to a position. This request may not take effect immediately; in the
+ future, when the compositor deems implementation-specific constraints
+ are satisfied, the pointer lock will be activated and the compositor
+ sends a locked event.
+
+ The protocol provides no guarantee that the constraints are ever
+ satisfied, and does not require the compositor to send an error if the
+ constraints cannot ever be satisfied. It is thus possible to request a
+ lock that will never activate.
+
+ There may not be another pointer constraint of any kind requested or
+ active on the surface for any of the wl_pointer objects of the seat of
+ the passed pointer when requesting a lock. If there is, an error will be
+ raised. See general pointer lock documentation for more details.
+
+ The intersection of the region passed with this request and the input
+ region of the surface is used to determine where the pointer must be
+ in order for the lock to activate. It is up to the compositor whether to
+ warp the pointer or require some kind of user interaction for the lock
+ to activate. If the region is null the surface input region is used.
+
+ A surface may receive pointer focus without the lock being activated.
+
+ The request creates a new object wp_locked_pointer which is used to
+ interact with the lock as well as receive updates about its state. See
+ the the description of wp_locked_pointer for further information.
+
+ Note that while a pointer is locked, the wl_pointer objects of the
+ corresponding seat will not emit any wl_pointer.motion events, but
+ relative motion events will still be emitted via wp_relative_pointer
+ objects of the same seat. wl_pointer.axis and wl_pointer.button events

+ <description summary="Primary selection protocol">
+ This protocol provides the ability to have a primary selection device to
+ match that of the X server. This primary selection is a shortcut to the
+ common clipboard selection, where text just needs to be selected in order
+ to allow copying it elsewhere. The de facto way to perform this action
+ is the middle mouse button, although it is not limited to this one.
+
+ Clients wishing to honor primary selection should create a primary
+ selection source and set it as the selection through
+ wp_primary_selection_device.set_selection whenever the text selection
+ changes. In order to minimize calls in pointer-driven text selection,
+ it should happen only once after the operation finished. Similarly,
+ a NULL source should be set when text is unselected.
+
+ wp_primary_selection_offer objects are first announced through the
+ wp_primary_selection_device.data_offer event. Immediately after this event,
+ the primary data offer will emit wp_primary_selection_offer.offer events
+ to let know of the mime types being offered.
+
+ When the primary selection changes, the client with the keyboard focus
+ will receive wp_primary_selection_device.selection events. Only the client
+ with the keyboard focus will receive such events with a non-NULL
+ wp_primary_selection_offer. Across keyboard focus changes, previously
+ focused clients will receive wp_primary_selection_device.events with a
+ NULL wp_primary_selection_offer.
+
+ In order to request the primary selection data, the client must pass
+ a recent serial pertaining to the press event that is triggering the
+ operation, if the compositor deems the serial valid and recent, the
+ wp_primary_selection_source.send event will happen in the other end
+ to let the transfer begin. The client owning the primary selection
+ should write the requested data, and close the file descriptor
+ immediately.
+
+ If the primary selection owner client disappeared during the transfer,
+ the client reading the data will receive a
+ wp_primary_selection_device.selection event with a NULL
+ wp_primary_selection_offer, the client should take this as a hint
+ to finish the reads related to the no longer existing offer.
+
+ The primary selection owner should be checking for errors during
+ writes, merely cancelling the ongoing transfer if any happened.

+ This protocol specifies a set of interfaces used for making clients able to
+ receive relative pointer events not obstructed by barriers (such as the

+
+ To start receiving relative pointer events, a client must first bind the
+ global interface "wp_relative_pointer_manager" which, if a compositor
+ supports relative pointer motion events, is exposed by the registry. After
+ having created the relative pointer manager proxy object, the client uses
+ it to create the actual relative pointer object using the

+ motion events will then, when applicable, be transmitted via the proxy of
+ the newly created relative pointer object. See the documentation of the

+ <description summary="Wayland protocol for graphics tablets">
+ This description provides a high-level overview of the interplay between
+ the interfaces defined this protocol. For details, see the protocol
+ specification.
+
+ More than one tablet may exist, and device-specifics matter. Tablets are
+ not represented by a single virtual device like wl_pointer. A client
+ binds to the tablet manager object which is just a proxy object. From
+ that, the client requests wp_tablet_manager.get_tablet_seat(wl_seat)
+ and that returns the actual interface that has all the tablets. With
+ this indirection, we can avoid merging wp_tablet into the actual Wayland
+ protocol, a long-term benefit.
+
+ The wp_tablet_seat sends a "tablet added" event for each tablet
+ connected. That event is followed by descriptive events about the
+ hardware; currently that includes events for name, vid/pid and
+ a wp_tablet.path event that describes a local path. This path can be
+ used to uniquely identify a tablet or get more information through
+ libwacom. Emulated or nested tablets can skip any of those, e.g. a
+ virtual tablet may not have a vid/pid. The sequence of descriptive
+ events is terminated by a wp_tablet.done event to signal that a client
+ may now finalize any initialization for that tablet.
+
+ Events from tablets require a tool in proximity. Tools are also managed
+ by the tablet seat; a "tool added" event is sent whenever a tool is new
+ to the compositor. That event is followed by a number of descriptive
+ events about the hardware; currently that includes capabilities,
+ hardware id and serial number, and tool type. Similar to the tablet
+ interface, a wp_tablet_tool.done event is sent to terminate that initial
+ sequence.
+
+ Any event from a tool happens on the wp_tablet_tool interface. When the
+ tool gets into proximity of the tablet, a proximity_in event is sent on
+ the wp_tablet_tool interface, listing the tablet and the surface. That
+ event is followed by a motion event with the coordinates. After that,
+ it's the usual motion, axis, button, etc. events. The protocol's
+ serialisation means events are grouped by wp_tablet_tool.frame events.
+
+ Two special events (that don't exist in X) are down and up. They signal
+ "tip touching the surface". For tablets without real proximity
+ detection, the sequence is: proximity_in, motion, down, frame.
+
+ When the tool leaves proximity, a proximity_out event is sent. If any
+ button is still down, a button release event is sent before this
+ proximity event. These button events are sent in the same frame as the
+ proximity event to signal to the client that the buttons were held when
+ the tool left proximity.
+
+ If the tool moves out of the surface but stays in proximity (i.e.
+ between windows), compositor-specific grab policies apply. This usually
+ means that the proximity-out is delayed until all buttons are released.
+
+ Moving a tool physically from one tablet to the other has no real effect
+ on the protocol, since we already have the tool object from the "tool
+ added" event. All the information is already there and the proximity
+ events on both tablets are all a client needs to reconstruct what
+ happened.
+
+ Some extra axes are normalized, i.e. the client knows the range as
+ specified in the protocol (e.g. [0, 65535]), the granularity however is
+ unknown. The current normalized axes are pressure, distance, and slider.
+
+ Other extra axes are in physical units as specified in the protocol.
+ The current extra axes with physical units are tilt, rotation and
+ wheel rotation.
+
+ Since tablets work independently of the pointer controlled by the mouse,
+ the focus handling is independent too and controlled by proximity.
+ The wp_tablet_tool.set_cursor request sets a tool-specific cursor.
+ This cursor surface may be the same as the mouse cursor, and it may be
+ the same across tools but it is possible to be more fine-grained. For
+ example, a client may set different cursors for the pen and eraser.
+
+ Tools are generally independent of tablets and it is
+ compositor-specific policy when a tool can be removed. Common approaches
+ will likely include some form of removing a tool when all tablets the
+ tool was used on are removed.
+
+ Warning! The protocol described in this file is experimental and
+ backward incompatible changes may be made. Backward compatible changes
+ may be added together with the corresponding interface version bump.
+ Backward incompatible changes are done by bumping the version number in
+ the protocol and interface names and resetting the interface version.
+ Once the protocol is to be declared stable, the 'z' prefix and the
+ version number in the protocol and interface names are removed and the
+ interface version number is reset.

+ <description summary="window decoration manager">
+ This interface allows a compositor to announce support for server-side

+
+ A window decoration is a set of window controls as deemed appropriate by

+
+ A client can use this protocol to request being decorated by a supporting
+ compositor.
+
+ If compositor and client do not negotiate the use of a server-side
+ decoration using this protocol, clients continue to self-decorate as they
+ see fit.
+
+ Warning! The protocol described in this file is experimental and
+ backward incompatible changes may be made. Backward compatible changes
+ may be added together with the corresponding interface version bump.
+ Backward incompatible changes are done by bumping the version number in
+ the protocol and interface names and resetting the interface version.
+ Once the protocol is to be declared stable, the 'z' prefix and the
+ version number in the protocol and interface names are removed and the
+ interface version number is reset.
