<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.
</description>
<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.

</request>
</interface>
<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>
<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.

<arg name="zone" type="int"/>
</request>
<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.
</description>
</entry>
</enum>
<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.

This assigns an xdg_popup's parent to this layer_surface. This popup
should have been created via xdg_surface::get_popup with the parent set
to NULL, and this request must be invoked before committing the popup's
initial state.

xdg_popup is and how it is used.

<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.

<description summary="destroy the layer_surface">

</request>
<event name="configure">
<description summary="suggest a surface change">
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.

longer be shown. The output may have been destroyed or the user may
have asked for it to be removed. Further changes to the surface will be
ignored. The client should destroy the resource after receiving this
event, and create a new surface if they so choose.

* @page page_xdg_output_unstable_v1 The xdg_output_unstable_v1 protocol
* Protocol to describe output regions
*
* @section page_desc_xdg_output_unstable_v1 Description
*
* This protocol aims at describing outputs in a way which is more in line
* with the concept of an output on desktop oriented systems.
*
* Some information are more specific to the concept of an output for
* a desktop oriented system and may not make sense in other applications,
* such as IVI systems for example.
*
* Typically, the global compositor space on a desktop system is made of
* a contiguous or overlapping set of rectangular regions.
*
* Some of the information provided in this protocol might be identical
* to their counterparts already available from wl_output, in which case
* the information provided by this protocol should be preferred to their
* equivalent in wl_output. The goal is to move the desktop specific
* concepts (such as output location within the global compositor space,
* the connector name and types, etc.) out of the core wl_output protocol.
*
* 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.

* size of the output in the global compositor space
*
* The logical_size event describes the size of the output in the
* global compositor space.
*
* For example, a surface without any buffer scale, transformation
* nor rotation set, with the size matching the logical_size will
* have the same size as the corresponding output when displayed.
*
* Most regular Wayland clients should not pay attention to the
* logical size and would rather rely on xdg_shell interfaces.
*
* Some clients such as Xwayland, however, need this to configure
* their surfaces in the global compositor space as the compositor
* may apply a different scale from what is advertised by the
* output scaling property (to achieve fractional scaling, for
* example).
*
* For example, for a wl_output mode 3840×2160 and a scale factor
* 2:
*
* - A compositor not scaling the surface buffers will advertise a
* logical size of 3840×2160,
*
* - A compositor automatically scaling the surface buffers will
* advertise a logical size of 1920×1080,
*
* - A compositor using a fractional scale of 1.5 will advertise a
* logical size of 2560×1440.
*
* For example, for a wl_output mode 1920×1080 and a 90 degree
* rotation, the compositor will advertise a logical size of
* 1080x1920.
*
* The logical_size event is sent after creating an xdg_output (see
* xdg_output_manager.get_xdg_output) and whenever the logical size
* of the output changes, either as a result of a change in the
* applied scale or because of a change in the corresponding output
* mode(see wl_output.mode) or transform (see wl_output.transform).
* @param width width in global compositor space
* @param height height in global compositor space

*

* client may wish to know this name as well to offer the user
* similar behaviors.
*
* The naming convention is compositor defined, but limited to
* alphanumeric characters and dashes (-). Each name is unique
* among all wl_output globals, but if a wl_output global is
* destroyed the same name may be reused later. The names will also
* remain consistent across sessions with the same hardware and
* software configuration.
*
* Examples of names include 'HDMI-A-1', 'WL-1', 'X11-1', etc.
* However, do not assume that the name is a reflection of an
* underlying DRM connector, X11 connection, etc.
*
* The name event is sent after creating an xdg_output (see
* xdg_output_manager.get_xdg_output). This event is only sent once
* per xdg_output, and the name does not change over the lifetime
* of the wl_output global.
