29 /* FUNCTION
30 This function adds a MenuStrip to the Window, which can be invoked
31 by the user after this call by pressing the right mouse button.
32 Menus with no MenuItems will not be attached.
34 INPUTS
35 window - The window to add the MenuStrip to
36 menu - The menu to be added to the window above.
38 RESULT
39 TRUE if all menus have at least one menuitem.
41 NOTES
42 This function calculates internal values and is therfore the
43 official way to add a new MenuStrip to Window.
44 Always do a ClearMenuStrip() before closing the Window or adding
45 another MenuStrip to the Window.
