implements java.awt.event.WindowListener, java.awt.event.WindowFocusListener, java.awt.event.WindowStateListener

The observable window listener which relays events from WindowListener, WindowFocusListener and WindowStateListener. The WindowEvent.getID() contains the original event type:

• WindowListener events:
  • WindowEvent.WINDOW_OPENED
  • WindowEvent.WINDOW_CLOSING
  • WindowEvent.WINDOW_CLOSED
  • WindowEvent.WINDOW_ICONIFIED
  • WindowEvent.WINDOW_DEICONIFIED
  • WindowEvent.WINDOW_ACTIVATED
  • WindowEvent.WINDOW_DEACTIVATEd
• WindowFocusListener events:
  • WindowEvent.WINDOW_GAINED_FOCUS
  • WindowEvent.WINDOW_LOST_FOCUS
• WindowStateListener events:
  • WindowEvent.WINDOW_STATE_CHANGED

This observable never signals finish() or error().
