Struct ReorderableListView 

pub struct ReorderableListView<State>
where
    State: 'static,
{ /* private fields */ }

A declarative drag-to-reorder list. See the module docs.

Implementations

impl<State> ReorderableListView<State>

where State: 'static,

pub fn on_reorder<F>(self, f: F) -> ReorderableListView<State>

where F: Fn(&mut State, usize, usize) + 'static,

Run f against the app state when a row drops onto a gap that moves it — never for a drop back onto its own current slot (see the module docs).

pub fn auto_scroll( self, controller: ScrollController, ) -> ReorderableListView<State>

Wrap the list in its own scroll surface bound to controller, then enclose that surface in edge auto-scroll for sessions on this list’s coordinator — so the zone’s edge bands measure the surface’s own (bounded) viewport, not the list’s full, usually taller, content. See super::auto_scroll_zone() and the module docs for the contract this puts on the caller: bound this view’s height from outside (a fixed-size ancestor), and do not also wrap it in a second scroll surface bound to the same controller.

Trait Implementations

impl<State> View<State> for ReorderableListView<State>

where State: 'static,

type Element = Box<dyn Widget>

The retained widget this view produces.

fn build( &self, ctx: &mut BuildCtx<'_>, ) -> <ReorderableListView<State> as View<State>>::Element

Materialise a fresh widget for this view.

fn rebuild( &self, prev: &ReorderableListView<State>, element: &mut <ReorderableListView<State> as View<State>>::Element, 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 <ReorderableListView<State> as View<State>>::Element, 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.
