Implementations

impl Compositor

pub fn new() -> Self

Create an empty compositor with no attached windows.

pub fn attach_window<W, E>( &mut self, window: W, options: AttachWindowOptions, emit: E, ) -> Result<CompositorWindowId, CompositorError>

where W: WindowHost + 'static, E: FnMut(BackendCommand) + 'static,

Attach a host-native window and return its compositor window id.

pub fn detach_window( &mut self, window_id: CompositorWindowId, emit: impl FnMut(BackendCommand), ) -> Result<(), CompositorError>

Detach a previously attached compositor window.

pub fn apply( &mut self, command: CompositionCommand, emit: impl FnMut(BackendCommand), ) -> Result<(), CompositorError>

Apply a declarative scene update to one attached window.

pub fn update_browser_event( &mut self, event: &BrowserEvent, emit: impl FnMut(BrowserCommand), ) -> Result<(), CompositorError>

Feed browser-generic backend events into the compositor state machine.

pub fn update_chrome_event( &mut self, event: &ChromeEvent, ) -> Result<(), CompositorError>

Feed Chrome-specific events into the compositor.

pub fn surface_target_for_item( &self, item_id: CompositionItemId, ) -> Option<SurfaceTarget>

Return the scene target currently displayed by an item.

pub fn item_ids_for_target( &self, target: SurfaceTarget, ) -> Vec<CompositionItemId>

Return every item currently showing the given target.

pub fn window_id_for_item( &self, item_id: CompositionItemId, ) -> Option<CompositorWindowId>

Return the compositor window that owns the given item.

pub fn set_active_item( &mut self, item_id: CompositionItemId, ) -> Result<(), CompositorError>

Programmatically move the active input target to one visible input-receiving item.

pub fn transient_preferred_size( &self, transient_browsing_context_id: TransientBrowsingContextId, ) -> Option<(u32, u32)>

Return the last preferred size hint reported for a transient popup.

pub fn show_context_menu( &mut self, target: SurfaceTarget, menu: ContextMenu, ) -> Result<(), CompositorError>

Present a host-owned context menu for the given surface target.

pub fn show_choice_menu( &mut self, target: SurfaceTarget, menu: ChromeChoiceMenu, ) -> Result<(), CompositorError>

pub fn start_native_drag( &mut self, request: DragStartRequest, ) -> Result<bool, CompositorError>
