    handler: impl WidgetHandler<InteractivityChangedArgs>,
) -> impl UiNode
Expand description

P Widget now looks enabled.

Note that this event tracks the visual enabled status of the widget, not the actual status, the widget may still be blocked, see Interactivity for more details.

Note that an event is received when the widget first initializes in the widget info tree if it starts visually enabled, this initial event can be detected using the is_new method in the args.

See on_vis_enabled_changed for a more general event.

§Preview

You can preview this event using on_pre_vis_enable. Otherwise the handler is only called after the widget content has a chance to stop propagation.

§Async

You can use async event handlers with this property.
