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 into scene. Paint may advance animation state; it must then call PaintCtx::request_frame until the animation rests.

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

Contribute accessibility node(s) after layout; defaults to none. A container forwards via ChildPod::semantics_child.

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

This widget as a sliver (crate::sliver), if it speaks that protocol. Defaults to None; transparent wrappers forward it.

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

Visit this widget’s owned ChildPods in paint order, for read-only tooling; defaults to none and must not mutate pass state.

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

This widget’s concrete type name, for diagnostics only (docs/LIMITATIONS.md focus-wrapper-erasure-swap-blind); override only in a transparent wrapper.

fn is_focusable(&self) -> bool

Whether keyboard traversal (Tab / Shift+Tab at the root) may stop on this widget’s pod.

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

Visit the children traversal may enter, in focus order; defaults to Widget::visit_children. A container showing only some children narrows it.
