All Implemented Interfaces:
  `Serializable, AccessibleComponent, AccessibleExtendedComponent, AccessibleValue`

Enclosing class:
  `JProgressBar`

protected class JProgressBar.AccessibleJProgressBar extends JComponent.AccessibleJComponent implements AccessibleValue
This class implements accessibility support for the `JProgressBar` class. It provides an implementation of the Java Accessibility API appropriate to progress bar 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`.

Since:
  1.2
