The Quintessential Accessible Object</h3>
You should try to subclass from JComponent or one of its descendents
since that will automatically make your object accessible. If that is
not possible, your object should implement Accessible.
<pre>
import javax.accessibility.*;
public class BasicAccessible implements Accessible {
public AccessibleContext getAccessibleContext() {
return new AccessibleContext() {
// Implement all the abstract methods in this abstract class.
};
}
}
