Menus are used extensively in most graphical user interfaces. Common Widgets provides protocol for pop-up menus, option menus and menu bars containing pull-down menus. Menu bars and menus are built using CwRowColumn widgets. Items in a menu bar are cascade buttons, which are buttons that drop down a menu when selected. Pop-up menus and pull-down menus within a menu bar are also represented by CwRowColumn widgets. Items within a menu are separators, labels, push buttons, toggle buttons, or cascade buttons for submenus. There are two ways to create menus: using simple menu convenience methods and using non-simple widget creation methods.
