Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Destroy

destroy the decoration object

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

This is a destructor, once received this object cannot be used any longer.

SetMode

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.

Fields of SetMode

mode: Mode

UnsetMode

unset the decoration mode

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.
