Optional capture and detachable-surface capability.

Provided Methods§

fn on_floating_surface_focus_changed( &mut self, _id: Option<&str>, _focused: bool, )

Route native keyboard focus to the exact presentation instance.

fn on_floating_surface_ime_source_changed(&mut self, _id: Option<&str>)

Keep the exact secondary presentation’s editor logically focused while the platform deliberately retains text-input focus on its source.

This is a host-authenticated input route, not a claim made by the app. The host clears it when the continuation ends or no longer validates.

fn on_floating_surface_event_source(&mut self, _id: Option<&str>)

Identify the native surface delivering the current input event. The host resets this immediately after dispatch; it grants no authority.

fn floating_surface_accessibility(&self, _id: &str) -> Option<AccessNode>

The retained semantic subtree presented in one secondary window.

fn perform_floating_surface_accessibility_action( &mut self, _id: &str, _target: &str, _action: &Action, _state: &mut Edits<'_>, _path: &ExId, ) -> bool

fn floating_surface_ime(&self, _id: &str) -> Option<(ImePurpose, Rect)>

IME purpose and desktop-logical caret rect for one secondary window.

fn take_floating_surface_request(&mut self) -> Option<FloatingSurfaceRequest>

One-shot request to hand app content to the shared floating-surface host. Shell and in-app hosts consume the same description, so PiP does not require a second rendering/widget API.

fn take_capture_studio_request(&mut self) -> Option<CaptureMode>

One-shot request for the session shell’s shared capture/PiP chooser.

fn take_floating_surface_source_updates(&mut self) -> Vec<(String, Rect)>

Rising-edge source-geometry updates for an adopted floating surface.

fn draw_floating_surfaces( &mut self, _scene: &mut Scene, _transform: Affine, _text_renderer: &mut TextRenderer, _theme: &Theme, _presence: &PresenceCtx, )

Paint app-owned content whose presentation has moved into shell space.

fn draw_floating_surface( &mut self, id: &str, scene: &mut Scene, transform: Affine, text_renderer: &mut TextRenderer, theme: &Theme, presence: &PresenceCtx, ) -> bool

Paint exactly one app-owned presentation into its native window.

Native secondary windows are independent buffers. Painting the plural overlay pass into each one can duplicate sibling surfaces and lets content escape the window’s own clip.
