Expand description

An update of an ItemsHost in progress.

Implementations§

Source§

impl<'a, T> ItemsCursor<'a, T>

Source

pub fn next( &mut self, key: u64, selected: bool, build: impl FnOnce() -> (T, Widget), ) -> Option<Item<'_, T>>

The next item, keyed key (see crate::screens::bind::key); build makes a new instance. None when it’s outside the visible window (virtualized lists) — skip its bindings.

Source

pub fn finish( self, empty: Option<fn() -> Widget>, ) -> Option<(&'a mut Widget, &'a mut Update)>

Ends the update. With empty (the .Empty template’s builder) and no items, shows that widget and returns it for its bindings.
