public interface TopLevelWindowListener
extends EventListener
The TopLevelWindowListener interface is used by the EventQueueMonitor
class to notify an interested party when a top level window is created
or destroyed in the Java Virtual Machine. Classes wishing to express
an interest in top level window events should implement this interface
and register themselves with the EventQueueMonitor by calling the
EventQueueMonitor.addTopLevelWindowListener
class method.
