Struct AnchoredOverlay

pub struct AnchoredOverlay<Msg: Clone> { /* private fields */ }

A wrapper that re-positions its child relative to an anchor widget found in the previous frame’s layout snapshot.

Implementations

impl<Msg: Clone> AnchoredOverlay<Msg>

pub fn new( child: impl Into<Element<Msg>>, anchor_id: WidgetId, gap: f32, ) -> Self

Wrap child so it draws anchored below the widget that carries anchor_id in its .id( … ) builder. gap is the vertical space (logical pixels) between the anchor’s bottom edge and the child’s top edge.

pub fn gap(self, gap: f32) -> Self

The vertical space, in physical pixels, between the anchor’s bottom edge and the child’s top edge. Default: 0.

pub fn align(self, align: HAlign) -> Self

Line the child up with the anchor’s left edge (Start, the default), its right edge (End) or its middle (Center).

pub fn resolve_rect(anchor: Option<Rect>, gap: f32, fallback: Rect) -> Rect

Compute the draw rect for the child, given the anchor rect (when available) and the parent-supplied fallback.

Anchor available → place the child flush below the anchor with gap spacing, preserving the anchor’s width. Anchor missing → return the parent rect verbatim, so the child renders modal-style as a fallback.

Trait Implementations

impl<Msg: Clone + 'static> From<AnchoredOverlay<Msg>> for Element<Msg>

fn from(a: AnchoredOverlay<Msg>) -> Self

Converts to this type from the input type.
