- All Implemented Interfaces:
    Serializable, AccessibleComponent, AccessibleExtendedComponent
  Enclosing class:
    JTableHeader

      protected class JTableHeader.AccessibleJTableHeader
      extends JComponent.AccessibleJComponent

  This class implements accessibility support for the `JTableHeader` class. It provides an implementation of the Java Accessibility API appropriate to table header 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 JavaBeansTM has been added to the `java.beans` package. Please see `XMLEncoder`.
