20  * Convenience Class to tunnel Events.
21  *
22  * Forwards Window Events like windowClosed to the WindowState listener.
23  * Usually, a WindowStateListener gets only state events (minimized,..)
24  * This allows implementing a single method (windowStateChanged)
25  * to receive potentially all window events.
26  * <p>
27  * Implemented:
28  * e.getID() == WindowEvent.WINDOW_CLOSED
