class Widgetmethod

beforeRender()

A method that’s called before the view is rendered, to be overridden if needed.

protected beforeRender(view: View): void;

Notes

• The default implementation emits a BeforeRender event. The event is never propagated because of the ObservableEvent.noPropagation flag.
