Struct Scene 

pub struct Scene { /* private fields */ }

An owned root view plus ordered overlays.

A scene is itself a View, so a host can pass it directly to paint. Overlays are rendered in insertion order and only the topmost one receives a focused render context.

Use ScopedScene when the root view borrows host-owned data that should not be cloned into this scene’s owned Element.

Implementations

impl Scene

pub fn new(root: Element) -> Self

Create a scene with no overlays.

pub fn overlay(self, overlay: SceneOverlay) -> Self

Add an owned overlay.

pub fn layer(self, view: Element, spec: OverlaySpec) -> Self

Add an owned view with a placement specification.

pub fn dialog(self, dialog: Dialog) -> Self

Add a dialog composition.

pub fn overlay_count(&self) -> usize

The number of overlay layers.

pub fn sync_focus(&self, focus: &mut FocusRegistry)

Synchronize exclusive input ownership with the topmost overlay.

Call this after constructing the frame’s scene. A scene without an owner-bearing overlay releases overlay ownership.

Trait Implementations

impl View for Scene

fn measure(&self, available: Size) -> Size

Report the intrinsic content size wanted given available.

fn render(&self, area: Rect, surface: &mut Surface<'_>, ctx: &RenderCtx<'_>)

Paint the view into the assigned area through surface.
