Description

The generic function merge-menu-bars is called by the system to compute the menu bar for a document-frame interface.

The set of visible menus in such an interface is typically made up from those of the frame and those of the active document within it.

There is a built-in unspecialized method that appends the menu bars of the two interfaces and is equivalent to this:

(defmethod capi:merge-menu-bars ((frame t)

                                 (document t))

  (append 

   (capi:interface-menu-bar-items frame)

   (and document

        (capi:interface-menu-bar-items document))))

You can customize the menu bar by adding methods which specialize on particular frame and document interface classes.
