Struct MenuView 

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

A declarative Material menu: a menu_panel inside the anchored host. See menu.

The host is composed fresh in each pass from the props below rather than retained: AnchoredOverlayView type-erases its content at construction, so there is no way to reach back into the panel and re-set one of its own props once it is inside.

Implementations

impl<State: 'static> MenuView<State>

pub fn anchor(self, anchor: &OverlayAnchor) -> Self

Anchor the menu to the rect anchor carries (see crate::overlay::OverlayAnchor).

pub fn side(self, side: OverlaySide) -> Self

Set the side the menu opens on (bottom by default).

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

Set the cross-axis alignment (start by default, the reference’s bottomStart).

pub fn offset(self, offset: f64) -> Self

Set the gap between trigger and menu (anchorOffset, 4dp by default).

pub fn color_style(self, style: MenuColorStyle) -> Self

Pick the standard or vibrant color resolution.

pub fn selected(self, value: Option<String>) -> Self

Hand the menu the app-confirmed selected value its MenuSelectable rows check against.

pub fn open(self, open: bool) -> Self

Hand a kept-mounted menu the app’s open flag, so closing it plays the host’s exit ramp instead of vanishing — and closes the whole submenu cascade on the spot.

pub fn on_dismiss<F: Fn(&mut State) + 'static>(self, on_dismiss: F) -> Self

Set the dismiss callback: a press outside the menu, or Escape once the host holds focus.

Trait Implementations

impl<State: 'static> View<State> for MenuView<State>

type Element = AnchoredOverlayWidget

fn build(&self, ctx: &mut BuildCtx<'_>) -> AnchoredOverlayWidget

Materialise a fresh widget for this view.

fn rebuild( &self, prev: &Self, element: &mut AnchoredOverlayWidget, ctx: &mut BuildCtx<'_>, ) -> ChangeFlags

Reconcile prev (the previous view of the same type) against the live element, mutating it in place and reporting what changed.

fn teardown(&self, element: &mut AnchoredOverlayWidget, ctx: &mut BuildCtx<'_>)

Tear down element when this view is being removed.

fn message(&self, _element: &mut Self::Element, _state: &mut State)
