Struct SliverFillRemainingWidget 

pub struct SliverFillRemainingWidget { /* private fields */ }

The retained widget for a SliverFillRemainingView: the child’s pod, the mode, and whether the last sliver layout cut the child (so paint clips it).

Trait Implementations

impl SliverWidget for SliverFillRemainingWidget

fn layout_sliver( &mut self, ctx: &mut LayoutCtx<'_>, sc: &SliverConstraints, ) -> SliverGeometry

Lay the sliver out under sc and report its geometry, which must satisfy SliverGeometry::debug_assert_valid against sc.

impl Widget for SliverFillRemainingWidget

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

Outside a viewport there is nothing to fill: the child is laid out under bc at the origin, uncut.

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

The viewport only delivers a positional event inside this sliver’s paint extent (or to a captured child), so the ordinary single-child routing applies.

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

Emit draw commands for this widget into scene.

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

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

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

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).

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.
