pub fn on_show(
    child: impl IntoUiNode,
    handler: Box<dyn FnMut(&VisibilityChangedArgs) -> HandlerResult + Send>,
) -> UiNode

Expand description

P Widget visibility changed to visible.

Note that widgets are already marked visible before the first render so this event does not fire on init.

§Preview

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

You can use async event handlers with this property.
