Class JScrollPane.AccessibleJScrollPane

All Implemented Interfaces:
PropertyChangeListener, Serializable, EventListener, AccessibleComponent, AccessibleExtendedComponent, ChangeListener
Enclosing class:
JScrollPane
protected class JScrollPane.AccessibleJScrollPane
extends JComponent.AccessibleJComponent
implements ChangeListener, PropertyChangeListener

This class implements accessibility support for the JScrollPane class. It provides an implementation of the Java Accessibility API appropriate to scroll pane 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.
