/** Part of a small example showing basic use of JToolBar.
 *  The point here is that dropping a regular JButton in a
 *  JToolBar (or adding an Action) in JDK 1.2 doesn't give 
 *  you what you want -- namely, a small button just enclosing
 *  the icon, and with text labels (if any) below the icon,
 *  not to the right of it. In JDK 1.3, if you add an Action
 *  to the toolbar, the Action label is no longer displayed.
