EventListener
AWTEventMulticaster
, HierarchyBoundsAdapter
public interface HierarchyBoundsListener extends EventListener
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 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 HierarchyEvent
is passed to it. 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 HierarchyBoundsListener
or not.
