pub struct PanelListRange { /* private fields */ }
Expand description

First and last child widget in a PanelList.

Implementations§

source§

impl PanelListRange

source

pub fn update( parent: &WidgetInfo, panel_id: impl Into<StateId<PanelListRange>>, last_version: &mut Option<u8>, ) -> Option<Children>

Gets the panel children if it may have changed since last_version.

The PanelList requests an update for each child after info rebuild if it has changed, the item properties can used this method on update to react.

source

pub fn get( parent: &WidgetInfo, panel_id: impl Into<StateId<PanelListRange>>, ) -> Option<Children>

Gets the panel children if the parent contains the panel_id.
