A DOM event (Event) is the DOM-level event that is usually triggered by the browser. It is usually listened by the implementation of a widget, rather than the client application.
Since ZK Client Engine intercepts most DOM events and encapsulate them into the widget events, it is suggested to listen the widget events, if possible, for better performance (by overriding the corresponding methods, such as Widget.doClick_(Event)). For more information, please refer to the previous section.
