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