protected class JList.AccessibleJList extends JComponent.AccessibleJComponent implements AccessibleSelection, PropertyChangeListener, ListSelectionListener, ListDataListener
This class implements accessibility support for the JList class. It provides an implementation of the Java Accessibility API appropriate to list user-interface elements.

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 JavaBeans has been added to the java.beans package. Please see XMLEncoder.
