<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.

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 a 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 a 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.

xdg_surface.ack_configure for details.

A configure event can be sent at any time. The specified mode must be
