TClassMenuItem Class Reference

Describes one element of the context menu associated to a class The menu item may describe.

  • a separator,
  • standard list of methods i.e. the methods defined in the described class by a MENU in the comment field of the header,
  • a method of an external class or a global function All the standard methods of the class are described by only one item. Since a complete context menu is described by a TList of TClassMenuItem elements, it is possible to customize the context menu of a class by removing the element "standard methods" and replacing it by whatever one wants.
