This type of event is generated when a window is created or deleted.
Event registration can be done as follows, where this is the class that implements IEventSubscriber<WindowEvent>
EventBroadcaster.getInstance().subscribe(WindowEvent.class, this);In the example below, we want to be notified if a certain layer is deleted. We do this in method onEvent which implements the IEventSubscriber<WindowEvent> interface:
private IWindow myWindow; // the window we want to keep track of
public void onEvent(WindowEvent event) {
if (event.getEventType().equals(WindowEvent.WINDOW_DELETED_EVENT_TYPE)) {
IWindow window = event.getWindow();
if (window == myWindow) {
// do some cleanup
EventBroadcaster.getInstance().unsubscribe(WindowEvent.class, this);
myWindow = null;
....
}
}
}
