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.

<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.

have asked for it to be removed. Further changes to the surface will be
