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.
