From Documentation
Property:
The org.zkoss.zk.ui.util.EventInterceptor interface
EventInterceptor is implemented by a listener class that will be used to intercept when an event is sent, posted and processed.
Once registered, an instance is created and shared within the whole application. If you want to intercept events only for a particular desktop, use Desktop.addListener(Object).
