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.
