Expand description

Modifiers for changing the behavior and selection state of a List.

Required Methods§

Source

fn selection<R>(self, selection: impl Res<R> + 'static) -> Self
where R: Deref<Target = [usize]> + Clone + 'static,

Sets the selected items of the list from signal of type indices.

Source

fn on_select<F>(self, callback: F) -> Self
where F: 'static + Fn(&mut EventContext<'_>, usize),

Sets the callback triggered when a ListItem is selected.

Source

fn selectable<U: Into<Selectable> + Clone + 'static>( self, selectable: impl Res<U> + 'static, ) -> Self

Set the selectable state of the List.

Source

fn min_selected(self, min_selected: impl Res<usize> + 'static) -> Self

Sets the minimum number of selected items.

Source

fn max_selected(self, max_selected: impl Res<usize> + 'static) -> Self

Sets the maximum number of selected items.

Source

fn selection_follows_focus<U: Into<bool> + Clone + 'static>( self, flag: impl Res<U> + 'static, ) -> Self

Sets whether the selection should follow the focus.

Source

fn horizontal<U: Into<bool> + Clone + 'static>( self, horizontal: impl Res<U> + 'static, ) -> Self

Sets the orientation of the list.

Source

fn scroll_to_cursor(self, flag: bool) -> Self

Sets whether the scrollbar should move to the cursor when pressed.

Source

fn on_scroll( self, callback: impl Fn(&mut EventContext<'_>, f32, f32) + 'static + Send + Sync, ) -> Self

Sets a callback which will be called when a scrollview is scrolled, either with the mouse wheel, touchpad, or using the scroll bars.

Source

fn scroll_x(self, scrollx: impl Res<f32> + 'static) -> Self

Set the horizontal scroll position of the ScrollView. Accepts a value or signal of type an f32 between 0 and 1.

Source

fn scroll_y(self, scrollx: impl Res<f32> + 'static) -> Self

Set the vertical scroll position of the ScrollView. Accepts a value or signal of type an f32 between 0 and 1.

Source

fn show_horizontal_scrollbar(self, flag: impl Res<bool> + 'static) -> Self

Sets whether the horizontal scrollbar should be visible.

Source

fn show_vertical_scrollbar(self, flag: impl Res<bool> + 'static) -> Self

Sets whether the vertical scrollbar should be visible.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
