xdg_decoration_unstable_v1 protocol

zxdg_decoration_manager_v1 interface version 1

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.

Requests

destroy (destructor) since version 0

Destroy the decoration manager. This doesn't destroy objects created with the manager.


get_toplevel_decoration since version 0

Create a new decoration object associated with the given toplevel. Creating an xdg_toplevel_decoration from an xdg_toplevel 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 xdg_toplevel_decoration.configure event must also be treated as errors.

Arguments
id (new_id) (zxdg_toplevel_decoration_v1)
toplevel (object) (xdg_toplevel)




zxdg_toplevel_decoration_v1 interface version 1

The decoration object allows the compositor to toggle server-side window decorations for a toplevel surface. The client can request to switch to another mode. The xdg_toplevel_decoration object must be destroyed before its xdg_toplevel.

Requests

destroy (destructor) since version 0

Switch back to a mode without any server-side decorations at the next commit.


set_mode since version 0

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.

Arguments
mode (uint) (mode)

the decoration mode


unset_mode since version 0

Unset the toplevel surface decoration mode. This informs the compositor that the client doesn't prefer a particular decoration mode. This request has the same semantics as set_mode.


Events

configure since version 0

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.

mode (uint) (mode)

the decoration mode
