protected class JSlider.AccessibleJSlider
extends JComponent.AccessibleJComponent
implements AccessibleValue, ChangeListener, AccessibleAction
This class implements accessibility support for the
 
JSlider class.  It provides an implementation of the
 Java Accessibility API appropriate to slider 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.
