  31  * The listener interface for receiving display change events.
  32  * The class that is interested in processing a display change event
  33  * implements this interface (and all the methods it
  34  * contains).
  35  *
  36  * For Motif, this interface is only used for dragging windows between Xinerama
  37  * screens.
  38  *
  39  * For win32, the listener object created from that class is then registered
  40  * with the WToolkit object using its {@code addDisplayChangeListener}
  41  * method. When the display resolution is changed (which occurs,
  42  * in Windows, either by the user changing the properties of the
  43  * display through the control panel or other utility or by
  44  * some other application which has gotten fullscreen-exclusive
  45  * control of the display), the listener is notified through its
  46  * displayChanged() or paletteChanged() methods.
