Detailed Description

Named property class.

Library: ilvgadgt

The class IlvMenuItemGroup is a named property that can be set on an IlvAbstractMenu object to implement menu items groups. A group of menu item is a list of menu item. The menu items are referenced by their name inside the group, and thus, changing the name of an item located in a group is not allowed. Furthermore, you must be aware that you cannot add a group to a menu if this menu already has a named property with the same name as the group.
