Interface Application.ExitListener

All Superinterfaces:
EventListener
Enclosing class:
Application
public static interface Application.ExitListener extends EventListener
Gives the Application a chance to veto an attempt to exit/quit. An ExitListener's canExit method should return false if there are pending decisions that the user must make before the app exits. A typical ExitListener would prompt the user with a modal dialog.

The eventObject argument will be the the value passed to exit(). It may be null.

The willExit method is called after the exit has been confirmed. An ExitListener that's going to perform some cleanup work should do so in willExit.

ExitListeners run on the event dispatching thread.
