<description summary="inter-proccess-communication about dwl's state">
This protocol allows clients to update and get updates from dwl.
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="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.

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

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

<interface name="zwlr_layer_shell_v1" version="4">
<description summary="create surfaces that are layers of the desktop">
Clients can use this interface to assign the surface_layer role to
wl_surfaces. Such surfaces are assigned to a "layer" of the output and
rendered with a defined z-depth respective to each other. They may also be
anchored to the edges and corners of a screen and specify input handling
semantics. This interface should be suitable for the implementation of
many desktop shell components, and a broad number of other applications
that interact with the desktop.

<request name="get_layer_surface">
<description summary="create a layer_surface from a surface">
Create a layer surface for an existing surface. This assigns the role of
layer_surface, or raises a protocol error if another role is already
assigned.
Creating a layer surface from a wl_surface which has a buffer attached
or committed is a client error, and any attempts by a client to attach
or manipulate a buffer prior to the first layer_surface.configure call
must also be treated as errors.
After creating a layer_surface object and setting it up, the client
must perform an initial commit without any buffer attached.
The compositor will reply with a layer_surface.configure event.
The client must acknowledge it and is then allowed to attach a buffer
to map the surface.
You may pass NULL for output to allow the compositor to decide which
output to use. Generally this will be the one that the user most
recently interacted with.
Clients can specify a namespace that defines the purpose of the layer
surface.

<interface name="zwlr_layer_surface_v1" version="4">
<description summary="layer metadata interface">
An interface that may be implemented by a wl_surface, for surfaces that
are designed to be rendered as a layer of a stacked desktop-like
environment.
Layer surface state (layer, size, anchor, exclusive zone,
margin, interactivity) is double-buffered, and will be applied at the
time wl_surface.commit of the corresponding wl_surface is called.
Attaching a null buffer to a layer surface unmaps it.
Unmapping a layer_surface means that the surface cannot be shown by the
compositor until it is explicitly mapped again. The layer_surface
returns to the state it had right after layer_shell.get_layer_surface.
The client can re-map the surface by performing a commit without any
buffer attached, waiting for a configure event and handling it as usual.
</description>
<request name="set_size">
<description summary="sets the size of the surface">
Sets the size of the surface in surface-local coordinates. The
compositor will display the surface centered with respect to its
anchors.
If you pass 0 for either value, the compositor will assign it and
inform you of the assignment in the configure event. You must set your
anchor to opposite edges in the dimensions you omit; not doing so is a
protocol error. Both values are 0 by default.
Size is double-buffered, see wl_surface.commit.

<request name="set_anchor">
<description summary="configures the anchor point of the surface">
Requests that the compositor anchor the surface to the specified edges
and corners. If two orthogonal edges are specified (e.g. 'top' and
'left'), then the anchor point will be the intersection of the edges
(e.g. the top left corner of the output); otherwise the anchor point
will be centered on that edge, or in the center if none is specified.
Anchor is double-buffered, see wl_surface.commit.
</description>
<arg name="anchor" type="uint" enum="anchor"/>
</request>
<request name="set_exclusive_zone">
<description summary="configures the exclusive geometry of this surface">
Requests that the compositor avoids occluding an area with other
surfaces. The compositor's use of this information is
implementation-dependent - do not assume that this region will not
actually be occluded.
A positive value is only meaningful if the surface is anchored to one
edge or an edge and both perpendicular edges. If the surface is not
anchored, anchored to only two perpendicular edges (a corner), anchored
to only two parallel edges or anchored to all edges, a positive value
will be treated the same as zero.
A positive zone is the distance from the edge in surface-local
coordinates to consider exclusive.
Surfaces that do not wish to have an exclusive zone may instead specify
how they should interact with surfaces that do. If set to zero, the
surface indicates that it would like to be moved to avoid occluding
surfaces with a positive exclusive zone. If set to -1, the surface
indicates that it would not like to be moved to accommodate for other
surfaces, and the compositor should extend it all the way to the edges
it is anchored to.
For example, a panel might set its exclusive zone to 10, so that
maximized shell surfaces are not shown on top of it. A notification
might set its exclusive zone to 0, so that it is moved to avoid
occluding the panel, but shell surfaces are shown underneath it. A
wallpaper or lock screen might set their exclusive zone to -1, so that
they stretch below or over the panel.
The default value is 0.
Exclusive zone is double-buffered, see wl_surface.commit.

<request name="set_margin">
<description summary="sets a margin from the anchor point">
Requests that the surface be placed some distance away from the anchor
point on the output, in surface-local coordinates. Setting this value
for edges you are not anchored to has no effect.
The exclusive zone includes the margin.
Margin is double-buffered, see wl_surface.commit.

<enum name="keyboard_interactivity">
<description summary="types of keyboard interaction possible for a layer shell surface">
Types of keyboard interaction possible for layer shell surfaces. The
rationale for this is twofold: (1) some applications are not interested
in keyboard events and not allowing them to be focused can improve the
desktop experience; (2) some applications will want to take exclusive
keyboard focus.
</description>
<entry name="none" value="0">
<description summary="no keyboard focus is possible">
This value indicates that this surface is not interested in keyboard
events and the compositor should never assign it the keyboard focus.
This is the default value, set for newly created layer shell surfaces.
This is useful for e.g. desktop widgets that display information or
only have interaction with non-keyboard input devices.
</description>
</entry>
<entry name="exclusive" value="1">
<description summary="request exclusive keyboard focus">
Request exclusive keyboard focus if this surface is above the shell surface layer.
For the top and overlay layers, the seat will always give
exclusive keyboard focus to the top-most layer which has keyboard
interactivity set to exclusive. If this layer contains multiple
surfaces with keyboard interactivity set to exclusive, the compositor
determines the one receiving keyboard events in an implementation-
defined manner. In this case, no guarantee is made when this surface
will receive keyboard focus (if ever).
For the bottom and background layers, the compositor is allowed to use
normal focus semantics.
This setting is mainly intended for applications that need to ensure
they receive all keyboard events, such as a lock screen or a password
prompt.
</description>
</entry>
<entry name="on_demand" value="2" since="4">
<description summary="request regular keyboard focus semantics">
This requests the compositor to allow this surface to be focused and
unfocused by the user in an implementation-defined manner. The user
should be able to unfocus this surface even regardless of the layer
it is on.
Typically, the compositor will want to use its normal mechanism to
manage keyboard focus between layer shell surfaces with this setting
and regular toplevels on the desktop layer (e.g. click to focus).
Nevertheless, it is possible for a compositor to require a special
interaction to focus or unfocus layer shell surfaces (e.g. requiring
a click even if focus follows the mouse normally, or providing a
keybinding to switch focus between layers).
This setting is mainly intended for desktop shell components (e.g.
panels) that allow keyboard interaction. Using this option can allow
implementing a desktop shell that can be fully usable without the
mouse.

<request name="set_keyboard_interactivity">
<description summary="requests keyboard events">
Set how keyboard events are delivered to this surface. By default,
layer shell surfaces do not receive keyboard events; this request can
be used to change this.
This setting is inherited by child surfaces set by the get_popup
request.
Layer surfaces receive pointer, touch, and tablet events normally. If
you do not want to receive them, set the input region on your surface
to an empty region.
Keyboard interactivity is double-buffered, see wl_surface.commit.

<description summary="ack a configure event">
When a configure event is received, if a client commits the
surface in response to the configure event, then the client
must make an ack_configure request sometime before the commit
request, passing along the serial of the configure event.
If the client receives multiple configure events before it
can respond to one, it only has to ack the last configure event.
A client is not required to commit immediately after sending
an ack_configure request - it may even ack_configure several times
before its next surface commit.
A client may send multiple ack_configure requests before committing, but
only the last request sent before a commit indicates which configure
event the client really is responding to.

The configure event asks the client to resize its surface.
Clients should arrange their surface for the new states, and then send
an ack_configure request with the serial sent in this configure event at
some point before committing the new surface.
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 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). If the client picks a smaller size and
is anchored to two opposite anchors (e.g. 'top' and 'bottom'), the
surface will be centered on this axis.
If the width or height arguments are zero, it means the client should
decide its own window dimension.
