Function zng::widget::on_block

pub fn on_block(
    child: impl UiNode,
    handler: impl WidgetHandler<InteractivityChangedArgs>,
) -> impl UiNode

P Widget interactions now blocked.

Note that blocked widgets may still be visually enabled, see Interactivity for more details.

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

See on_blocked_changed for a more general event.

Preview

You can preview this event using on_pre_block. 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.
