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

many desktop shell components, and a broad number of other applications

Requests that the compositor anchor the surface to the specified edges
|
||||||
|
and corners. If two orthoginal 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.

<request name="set_exclusive_zone">

|
<description summary="configures the exclusive geometry of this surface">
|
||||||
|
Requests that the compositor avoids occluding an area of the surface
|
||||||
|
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 an
|
||||||
|
edge, rather than a corner. The zone is the number of surface-local
|
||||||
|
coordinates from the edge that are considered 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 excluzive zone. If set to -1, the surface
|
||||||
|
indicates that it would not like to be moved to accomodate 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.

point on the output, in surface-local coordinates. Setting this value

for edges you are not anchored to has no effect.

The width and height arguments specify the size of the window in

The size is a hint, in the sense that the client is free to ignore it if

resize in steps of NxM pixels). If the client picks a smaller size and
