| java.awt | Contains all of the classes for creating user
interfaces and for painting graphics and images. | 
| java.awt.event | Provides interfaces and classes for dealing with different
types of events fired by AWT components. | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | AWTEventMulticasterAWTEventMulticasterimplements efficient and thread-safe multi-cast
 event dispatching for the AWT events defined in thejava.awt.eventpackage. | 
| Modifier and Type | Method and Description | 
|---|---|
| static HierarchyBoundsListener | AWTEventMulticaster. add(HierarchyBoundsListener a,
   HierarchyBoundsListener b)Adds hierarchy-bounds-listener-a with hierarchy-bounds-listener-b and
 returns the resulting multicast listener. | 
| HierarchyBoundsListener[] | Component. getHierarchyBoundsListeners()Returns an array of all the hierarchy bounds listeners
 registered on this component. | 
| static HierarchyBoundsListener | AWTEventMulticaster. remove(HierarchyBoundsListener l,
      HierarchyBoundsListener oldl)Removes the old hierarchy-bounds-listener from
 hierarchy-bounds-listener-l and returns the resulting multicast
 listener. | 
| Modifier and Type | Method and Description | 
|---|---|
| static HierarchyBoundsListener | AWTEventMulticaster. add(HierarchyBoundsListener a,
   HierarchyBoundsListener b)Adds hierarchy-bounds-listener-a with hierarchy-bounds-listener-b and
 returns the resulting multicast listener. | 
| void | Component. addHierarchyBoundsListener(HierarchyBoundsListener l)Adds the specified hierarchy bounds listener to receive hierarchy
 bounds events from this component when the hierarchy to which this
 container belongs changes. | 
| static HierarchyBoundsListener | AWTEventMulticaster. remove(HierarchyBoundsListener l,
      HierarchyBoundsListener oldl)Removes the old hierarchy-bounds-listener from
 hierarchy-bounds-listener-l and returns the resulting multicast
 listener. | 
| void | Component. removeHierarchyBoundsListener(HierarchyBoundsListener l)Removes the specified hierarchy bounds listener so that it no longer
 receives hierarchy bounds events from this component. | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | HierarchyBoundsAdapterAn abstract adapter class for receiving ancestor moved and resized events. |
