 public class AncestorEvent extends AWTEvent An event reported to a child component that originated from an ancestor in the component hierarchy.Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the java.beanspackage. Please seeXMLEncoder.

- Constant Field Values
 
 -

Constructor Detail- 
AncestorEventpublic AncestorEvent(JComponent source, int id, Container ancestor, Container ancestorParent) Constructs an AncestorEvent object to identify a change in an ancestor-component's display-status.- Parameters:
- source- the JComponent that originated the event (typically- this)
- id- an int specifying- ANCESTOR_ADDED,- ANCESTOR_REMOVEDor- ANCESTOR_MOVED
- ancestor- a Container object specifying the ancestor-component whose display-status changed
- ancestorParent- a Container object specifying the ancestor's parent

Method Detail- 
getAncestorpublic Container getAncestor() Returns the ancestor that the event actually occurred on.
 - 
getAncestorParentpublic Container getAncestorParent() Returns the parent of the ancestor the event actually occurred on. This is most interesting in an ANCESTOR_REMOVED event, as the ancestor may no longer be in the component hierarchy.
 - 
getComponentpublic JComponent getComponent() Returns the component that the listener was added to.
