public class AppletContext
extends javax.swing.JApplet
implements AppContext

A context for an applet in the diva.gui infrastructure. Generally, all this class does is to pipe the AppContext method through to the appropriate method in the JFrame class. The exit action will be fired when the applet's destroy method is executed. The default exit action does nothing.
