Class HierarchyBoundsAdapter
java.lang.Object
java.awt.event.HierarchyBoundsAdapter
- All Implemented Interfaces:
HierarchyBoundsListener
,EventListener
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.
