<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

<interface name="zwp_pointer_constraints_v1" version="1">
<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
and with any of the wl_pointer objects of the same seat, an
'already_constrained' error will be raised.

<request name="lock_pointer">
<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
are unaffected.

<description summary="protocol for relative pointer motion events">
This protocol specifies a set of interfaces used for making clients able to
receive relative pointer events not obstructed by barriers (such as the
monitor edge or other pointer barriers).
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
"get_relative_pointer" request given a wl_pointer. The relative pointer
motion events will then, when applicable, be transmitted via the proxy of
the newly created relative pointer object. See the documentation of the
relative pointer interface 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
reset.

<description summary="relative pointer motion">
Relative x/y pointer motion from the pointer of the seat associated with
this object.
A relative motion is in the same dimension as regular wl_pointer motion
events, except they do not represent an absolute position. For example,
moving a pointer from (x, y) to (x', y') would have the equivalent
relative motion (x' - x, y' - y). If a pointer motion caused the
absolute pointer position to be clipped by for example the edge of the
monitor, the relative motion is unaffected by the clipping and will
represent the unclipped motion.
This event also contains non-accelerated motion deltas. The
non-accelerated delta is, when applicable, the regular pointer motion
delta as it was before having applied motion acceleration and other
transformations such as normalization.
Note that the non-accelerated delta does not represent 'raw' events as
they were read from some device. Pointer motion acceleration is device-
and configuration-specific and non-accelerated deltas and accelerated
deltas may have the same value on some devices.
Relative motions are not coupled to wl_pointer.motion events, and can be
sent in combination with such events, but also independently. There may
also be scenarios where wl_pointer.motion is sent, but there is no
relative motion. The order of an absolute and relative motion event
originating from the same physical motion is not guaranteed.
If the client needs button events or focus state, it can receive them
from a wl_pointer object of the same seat that the wp_relative_pointer
object is associated with.
