| /** |
| * The listener interface for receiving ancestor moved and resized events. |
| * The class that is interested in processing these events either implements |
| * this interface (and all the methods it contains) or extends the abstract |
| * {@code HierarchyBoundsAdapter} class (overriding only the method of |
| * interest). |
| * The listener object created from that class is then registered with a |
| * Component using the Component's {@code addHierarchyBoundsListener} |
| * method. When the hierarchy to which the Component belongs changes by |
| * the resizing or movement of an ancestor, the relevant method in the listener |
| * object is invoked, and the {@code HierarchyEvent} 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 works properly regardless of whether a |
| * program registers an {@code HierarchyBoundsListener} or not. |
