Menu
Synopsis
This System.ComponentModel.Component
is the
abstract base for ContextMenu
,
MainMenu
, and MenuItem
classes.
It provides most of the functionality of each of these classes but
cannot be instantiated itself.
You can add MenuItem
objects to the menu through
the MenuItems
collection. A
MenuItem
itself can contain further
MenuItem
objects, to allow for cascading child
menus. You can determine if the menu has any children through the
IsParent
property.
You can also determine which menu item is a special
MdiListItem
—an item that will display a list
of MDI child forms as a child menu. This is a read-only
property—you set it through the
MenuItem.MdiList
property.
The Menu
may be hosted in either a
ContextMenu
or a MainMenu
, and
you can determine which through the GetContextMenu()
and GetMainMenu()
methods.
Finally, there is a MergeMenu()
method. This
merges two menus together (performed automatically for MDI child
menus). There is nothing to stop you from using it for your own menu
management, however. It is particularly useful where you have a UI
plug-in architecture, where various components provide their own
little bit of menu structure that you can merge in to the overall
menu hierarchy. To control the merge, specify the
MenuItem.MergeOrder
and
MenuItem.MergeType
properties (see
MenuItem
for more information on this).
