## Class HierarchyBoundsAdapter

- java.lang.Object
- - java.awt.event.HierarchyBoundsAdapter

- All Implemented Interfaces:
    HierarchyBoundsListener, EventListener

      public abstract class HierarchyBoundsAdapter
      extends Object
      implements HierarchyBoundsListener

  An abstract adapter class for receiving ancestor moved and resized events. The methods in this class are empty. This class exists as a convenience for creating listener objects.

  Extend this class and override the method for the event of interest. (If you implement the `HierarchyBoundsListener` interface, you have to define both methods in it. This abstract class defines null methods for them both, so you only have to define the method for the event you care about.)

  Create a listener object using your class and then register it with a Component using the Component's `addHierarchyBoundsListener` method. When the hierarchy to which the Component belongs changes by resize or movement of an ancestor, the relevant method in the listener object is invoked, and the `HierarchyEvent` is passed to it.
