This class is the base class for the MainMenu, MenuItem, and ContextMenu classes. You cannot create an instance of this class. The menus for an application consist of MenuItem objects. These can contain other MenuItem objects, representing submenu items. The MenuItem objects can be stored in a MainMenu for display as an entire menu structure for a form or a ContextMenu that is used to display shortcut menus. This class provides functionality that is common for all the menu classes.
Unlike many base classes, the class uses its derived classes to define many of its properties. If you are using your menu in a multiple-document interface (MDI) application, you can use the MdiListItem property to specify a MenuItem that displays a list of open MDI child forms in your application. The MenuItems property contains a list of MenuItem objects stored in the menu class. For a MainMenu or ContextMenu, this property contains all the MenuItem objects that are displayed. For a MenuItem, the MenuItems property represents the submenu items associated with it.
In addition to the properties that are provided for all the derived menu classes, the class also provides methods, such as CloneMenu and MergeMenu, that enable you to create new menus from existing menus, and also merge two menu structures together.
The class also defines the nested class Menu.MenuItemCollection. This class defines the collection of MenuItem objects used by the MenuItems property. You can use the methods of the Menu.MenuItemCollection class to add and remove menu items from a MainMenu, ContextMenu, or MenuItem.
The following code example uses the derived class, MenuItem, to create a menu structure for a form. The example code adds a MenuItem to represent the top-level menu item, adds a submenu item to it for selecting a font size, and then adds two submenu items to that menu item that represent large and small font choices in an application. The example requires that there is a MainMenu object named mainMenu1 and four MenuItem objects named menuItem1, menuItem2, menuItem3, and menuItem4.
