<description summary="window decoration manager">
|
||||||
|
This interface allows a compositor to announce support for server-side
|
||||||
|
decorations.
|
||||||
|
|
||||||
|
A window decoration is a set of window controls as deemed appropriate by
|
||||||
|
the party managing them, such as user interface components used to move,
|
||||||
|
resize and change a window's state.
|
||||||
|
|
||||||
|
A client can use this protocol to request being decorated by a supporting
|
||||||
|
compositor.
|
||||||
|
|
||||||
|
If compositor and client do not negotiate the use of a server-side
|
||||||
|
decoration using this protocol, clients continue to self-decorate as they
|
||||||
|
see fit.
|
||||||
|
|
||||||
|
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="set the decoration mode">
|
||||||
|
Set the toplevel surface decoration mode. This informs the compositor
|
||||||
|
that the client prefers the provided decoration mode.
|
||||||
|
|
||||||
|
After requesting a decoration mode, the compositor will respond by
|
||||||
|
emitting an xdg_surface.configure event. The client should then update
|
||||||
|
its content, drawing it without decorations if the received mode is
|
||||||
|
server-side decorations. The client must also acknowledge the configure
|
||||||
|
when committing the new content (see xdg_surface.ack_configure).
|
||||||
|
|
||||||
|
The compositor can decide not to use the client's mode and enforce a
|
||||||
|
different mode instead.
|
||||||
|
|
||||||
|
Clients whose decoration mode depend on the xdg_toplevel state may send
|
||||||
|
a set_mode request in response to an xdg_surface.configure event and wait
|
||||||
|
for the next xdg_surface.configure event to prevent unwanted state.
|
||||||
|
Such clients are responsible for preventing configure loops and must
|
||||||
|
make sure not to send multiple successive set_mode requests with the
|
||||||
|
same decoration mode.

Unset the toplevel surface decoration mode. This informs the compositor

The configure event asks the client to change its decoration mode. The

|
configured state should not be applied immediately. Clients must send an
|
||||||
|
ack_configure in response to this event. See xdg_surface.configure and
|
||||||
|
xdg_surface.ack_configure for details.
|
||||||
|
|
||||||
|
A configure event can be sent at any time. The specified mode must be
|
||||||
|
obeyed by the client.
