Interface ZNodeContainerListener

All Known Implementing Classes:

ZAncestorNotifier, ZNodeContainerAdapter

public abstract interface ZNodeContainerListener

extends java.util.EventListener

ZNodeContainerListener

Interface to support notification when nodes are added or removed from a ZNode. Based on Swing's ContainerListener.

The listener interface for receiving ZNodeContainer events. The class that is interested in processing a ZNodeContainer event either implements this interface (and all the methods it contains) or extends the abstract ZNodeContainerAdapter class (overriding only the methods of interest). The listener object created from that class is then registered with a ZNode using the ZNode's addNodeContainerListener method. When a node is added or removed from a ZNode, the relevant method in the listener object is invoked, and the ZNodeContainerEvent is passed to it.

ZNodeContainer events are provided for notification purposes ONLY; The AWT will automatically handle ZNode adds and removes internally so that GUI layout works properly regardless of whether a program registers a ZNodeContainerListener or not.
