It is also generated by a Component object when that object's 0N/A * <code>addNotify</code>, <code>removeNotify</code>, <code>show</code>, or 217N/A * <code>hide</code> method is called. The {@code ANCESTOR_MOVED} and 217N/A * {@code ANCESTOR_RESIZED} 0N/A * events are dispatched to every <code>HierarchyBoundsListener</code> or 0N/A * <code>HierarchyBoundsAdapter</code> object which registered to receive 0N/A * such events using the Component's <code>addHierarchyBoundsListener</code> 0N/A * method. (<code>HierarchyBoundsAdapter</code> objects implement the <code> 217N/A * HierarchyBoundsListener</code> interface.) The {@code HIERARCHY_CHANGED} events are 0N/A * dispatched to every <code>HierarchyListener</code> object which registered 0N/A * to receive such events using the Component's <code>addHierarchyListener 0N/A * </code> method. Each such listener object gets this <code>HierarchyEvent 0N/A * </code> when the event occurs. 217N/A * An unspecified behavior will be caused if the {@code id} parameter 217N/A * of any particular {@code HierarchyEvent} instance is not 217N/A * in the range from {@code HIERARCHY_FIRST} to {@code HIERARCHY_LAST}. 217N/A * The {@code changeFlags} parameter of any {@code HierarchyEvent} instance takes one of the following 217N/A * <li> {@code HierarchyEvent.PARENT_CHANGED} 217N/A * <li> {@code HierarchyEvent.DISPLAYABILITY_CHANGED} 217N/A * <li> {@code HierarchyEvent.SHOWING_CHANGED} 217N/A * Assigning the value different from listed above will cause unspecified behavior. 0N/A * @author David Mendenhall 0N/A * @see HierarchyListener 0N/A * @see HierarchyBoundsAdapter 0N/A * @see HierarchyBoundsListener 0N/A * Marks the first integer id for the range of hierarchy event ids. 0N/A public static final int HIERARCHY_FIRST =
