<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 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.

|

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.

Sets the size of the surface in surface-local coordinates. The

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.

Requests that the compositor anchor the surface to the specified edges

|
||||
(e.g. the top left corner of the output); otherwise the anchor point
|

<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.

for edges you are not anchored to has no effect.
|

The exclusive zone includes the margin.

<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.

<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.

<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.
