import java.util.EventListener;

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