Trait Implementations

impl<A: Widget, B: Widget, C: Widget, D: Widget, E: Widget, F: Widget, G: Widget> Widget for EitherOf7Widget<A, B, C, D, E, F, G>

fn type_name(&self) -> &'static str

Report the live arm’s name: the enum is a storage detail, never a tree element in its own right.

fn layout(&mut self, ctx: &mut LayoutCtx<'_>, bc: &BoxConstraints) -> Size

Choose a size within bc and return it. The chosen size must satisfy bc (callers may additionally clamp via BoxConstraints::constrain).

fn paint(&mut self, ctx: &mut PaintCtx<'_>, scene: &mut dyn PaintScene)

Emit draw commands for this widget into scene.

fn event(&mut self, ctx: &mut EventCtx<'_>, event: &InputEvent) -> EventResult

Handle an input event, optionally mutating application state through ctx and reporting whether it was consumed.

fn semantics(&self, ctx: &mut SemanticsCtx)

Contribute this widget’s accessibility node(s) into ctx.

fn visit_children(&self, visitor: &mut dyn FnMut(&ChildPod))

Visit this widget’s owned ChildPods, in declaration (paint) order — the read-only seam that makes the retained hierarchy enumerable.
