SWI-Prolog -- win_insert

win_insert_menu(+Label, +Before)

Insert a new entry (pulldown) in the menu. If the menu already contains this entry, nothing is done. The Label is the label and, using the Windows convention, a letter prefixed with & is underlined and defines the associated accelerator key. Before is the label before which this one must be inserted. Using - adds the new entry at the end (right). For example, the call below adds an Application entry just before the Help menu.

win_insert_menu('&Application', '&Help')
