Chapter 9. Working with Menus

Rarely a serious UI application go by without menus. Menus are handy because they take only little space out of the screen real estate. Also, only a menu bar needs to appear at all times. Most menu items are in fact hidden and do not take space at all. To use menus, first add a menu bar to the container and add menus to the menu bar. Then, add menu items to a menu. To support hierarchical menus, you can add menu items to a menu item.

In OpenLaszlo, a menu bar is represented by the Menubar class, a menu by the Menu class, and a menu item by the Menuitem class. In this chapter you will learn about menus and how to use them.
