public class JTextComponent.AccessibleJTextComponent extends JComponent.AccessibleJComponent implements AccessibleText, CaretListener, DocumentListener, AccessibleAction, AccessibleEditableText, AccessibleExtendedText
This class implements accessibility support for the
JTextComponent
class. It provides an implementation of
the Java Accessibility API appropriate to menu 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 {@link java.beans.XMLEncoder}.
