Struct RichTooltipWidget 

pub struct RichTooltipWidget<State: 'static> { /* private fields */ }

The retained widget for a RichTooltipView: one OverlaySlot holding the rich panel, registered on every paint the latch reads open and on no other. See TooltipWidget for what that gates, and this view’s own configure for how the two panels’ registrations differ.

Trait Implementations

impl<State: 'static> Widget for RichTooltipWidget<State>

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.

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

This widget’s concrete type name, for read-only tooling.

fn as_sliver(&mut self) -> Option<&mut (dyn SliverWidget + 'static)>

This widget as a sliver, if it speaks the sliver protocol — the opt-in seam a scrolling viewport lays its children out through (see crate::sliver and ChildPod::layout_sliver_child).
