Interface EnableNotifier

All Known Implementing Classes:

G9MenuItem

public interface EnableNotifier

A notifier interface. Classes interesting in fiering an EnableEvent when the setEnable method is invoked should implement this interface, and override the setEnabled method to fire the event.

The reason one cannot use a regular property change listener is that the property event only fires if the property is changed, but we need to be notified regardles.
