Struct OverlayModifier 

pub struct OverlayModifier {
    pub overlay: AnyView,
    pub alignment: Alignment,
    pub offset: [f32; 2],
    pub on_dismiss: Option<Arc<dyn Fn() + Send + Sync>>,
}

Modifier to render a popover, tooltip, or menu view overlaying an anchored view. It supports alignment positioning and outside-click dismissal.

Fields

overlay: AnyView

The overlay content view.

alignment: Alignment

Where the overlay is aligned relative to the anchored view.

offset: [f32; 2]

Additional offset in logical pixels.

on_dismiss: Option<Arc<dyn Fn() + Send + Sync>>

Optional dismissal callback triggered by click-outside events.

Performs copy-assignment from source.

impl ViewModifier for OverlayModifier

fn modify<V: View>(self, content: V) -> impl View

Wraps the child view in a ModifiedView using this overlay modifier.

fn render_view<V: View>( &self, view: &V, renderer: &mut dyn Renderer, rect: Rect, )

Renders the overlay content positioned above the child view.

fn get_grid_placement(&self) -> Option<GridPlacement>

Returns the grid placement configuration if this modifier defines one.

fn render(&self, _renderer: &mut dyn Renderer, _rect: Rect)

Core rendering hook called before child views.

fn post_render(&self, _renderer: &mut dyn Renderer, _rect: Rect)

Cleanup hook called after child views.

fn transform_rect(&self, rect: Rect) -> Rect

fn transform_proposal(&self, proposal: SizeProposal) -> SizeProposal

Allows a modifier to transform the layout proposal before it reaches the child.

fn transform_size(&self, size: Size) -> Size

Allows a modifier to transform the resulting size from the child.

fn measure_view<V: View>( &self, view: &V, renderer: &mut dyn Renderer, proposal: SizeProposal, ) -> Size

Measure hook that coordinates size propagation.

fn child_flex_weight<V: View>(&self, view: &V) -> f32

Allows a modifier to override or pass through the child’s flex weight.
