Struct Subsurface

pub struct Subsurface { /* private fields */ }

Implementations

impl Subsurface

pub fn new(surface: ObjectId, parent: ObjectId) -> Self

pub fn surface(&self) -> ObjectRef<Surface>

Gets the associated wl_surface for this subsurface.

pub fn is_sync(&self) -> bool

Returns true iff this subsurface is running in synchronized mode.

pub fn add_pending_commands(&mut self, commands: Vec<SurfaceCommand>)

Adds some SurfaceCommands to this surfaces pending state.

This pending state is a set of operations that were committed with a wl_surface::commit request, but are waiting for our parents state to be committed.

Subsurfaces in desync mode have no pending state, as their state is applied immediately upon wl_surface::commit.

pub fn take_pending_state( &mut self, ) -> (Vec<SurfaceCommand>, Vec<ObjectRef<Callback>>)

Extracts the set of pending SurfaceCommands and frame Callbacks for this subsurface, resetting both to empty vectors.

pub fn finalize_commit( &mut self, callbacks: &mut Vec<ObjectRef<Callback>>, ) -> bool

Trait Implementations

impl RequestReceiver<WlSubsurface> for Subsurface

fn receive( this: ObjectRef<Self>, request: WlSubsurfaceRequest, client: &mut Client, ) -> Result<(), Error>

Handle a decoded message for the associated |Interface|.
