<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
reset.
</description>
<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>
<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="receive relative pointer motion events">
The wp_locked_pointer interface represents a locked pointer state.
While the lock of this object is active, the wl_pointer objects of the
associated seat will not emit any wl_pointer.motion events.
This object will send the event 'locked' when the lock is activated.
Whenever the lock is activated, it is guaranteed that the locked surface
will already have received pointer focus and that the pointer will be
within the region passed to the request creating this object.
To unlock the pointer, send the destroy request. This will also destroy
the wp_locked_pointer object.
If the compositor decides to unlock the pointer the unlocked event is
sent. See wp_locked_pointer.unlock for details.
When unlocking, the compositor may warp the cursor position to the set
cursor position hint. If it does, it will not result in any relative
motion events emitted via wp_relative_pointer.
If the surface the lock was requested on is destroyed and the lock is not
yet activated, the wp_locked_pointer object is now defunct and must be
destroyed.

jumps.
The cursor position hint is double buffered. The new hint will only take
effect when the associated surface gets it pending state applied. See

requires some user interaction and if the pointer will warp to within the

To unconfine the pointer, send the destroy request. This will also destroy
