12/** \class TClassMenuItem
13Describes one element of the context menu associated to a class
14The menu item may describe
15 - a separator,
16 - standard list of methods i.e. the methods defined in
17 the described class by a *MENU* in the comment field
18 of the header,
19 - a method of an external class or a global function
20All the standard methods of the class are described by only
21one item. Since a complete context menu is described by a TList of
22TClassMenuItem elements, it is possible to customize the context
23menu of a class by removing the element "standard methods" and
24replacing it by whatever one wants.
