  ch.claudio.pen.Menu

public class Menu
extends java.lang.Object

One way to present multi level menu in just one rectangle. Let's say the main menu is A. B. C, and A has a submenu Aa, Ab, Ac and Ac has a submenu Ac1, Ac2, Ac3, Ac4. The first menu presents the items A, B, C all with a bright background (e.g. white). If the user selects A the menu is replaced with a new one containing A, Aa, Ab, Ac where A has a darker background (e.g. light grey) while Aa, Ab and Ac have the bright background. The user can click on A and will get back to the main menu, or click on Ac to get one submen down. In that case the menu will contain A, Ac, Ac1, Ac2, Ac3 and Ac4 where A and Ac have a darker and Ac1, Ac2, Ac3 and Ac4 a bright background. This scheme assumes, that a node is either an action node or contains a submenu.
