Struct SelectionAppBarView 

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

A declarative selection-aware app bar: idle content, swapping to a contextual toolbar while selected is non-empty. See the module docs’ Contextual bar section.

Implementations

impl<State: 'static> SelectionAppBarView<State>

pub fn actions(self, actions: Vec<AnyView<State>>) -> Self

Attach contextual trailing action slots, in reading order (M3ESelectionAppBar.actions).

pub fn show_select_all(self, show: bool) -> Self

Whether to show the select-all row in the contextual toolbar. Defaults to true.

pub fn select_all_label(self, label: impl Into<String>) -> Self

Override the select-all row’s label. Defaults to "Select all".

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

Fire when the select-all row is toggled — true means the app should adopt select_all(item_count), false means cleared() (M3ESelectionAppBar.onAllSelected). Absent by default: toggling select-all with no callback set is a no-op.

Trait Implementations

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

type Element = SelectionAppBarWidget

The retained widget this view produces.

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

Materialise a fresh widget for this view.

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

Tear down element when this view is being removed.

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

Deliver an event message to this view, mutating application state.
