All Implemented Interfaces:
ActionListener, ImageObserver, ItemSelectable, MenuContainer, Serializable, EventListener, Accessible, MenuElement, SwingConstants

public class HelpSystem
extends JMenu
implements ActionListener

HelpSystem creates a JMenu of Help Topics, each of which will automatically open a HTMLInternalFrame with the specified URL when clicked. This system is pretty lightweight and easy to use, but not as feature-rich as Sun's jHelp.
