/**
 * The listener interface for receiving hierarchy changed events.
 * The class that is interested in processing a hierarchy changed event
 * should implement this interface.
 * The listener object created from that class is then registered with a
 * Component using the Component's <code>addHierarchyListener</code>
 * method. When the hierarchy to which the Component belongs changes, the
 * <code>hierarchyChanged</code> method in the listener object is invoked,
 * and the <code>HierarchyEvent</code> is passed to it.
 * <p>
 * Hierarchy events are provided for notification purposes ONLY;
 * The AWT will automatically handle changes to the hierarchy internally so
 * that GUI layout, displayability, and visibility work properly regardless
 * of whether a program registers a <code>HierarchyListener</code> or not.
