I don't know if there is a way to do it, and I'm afraid there is no official/documented way to do this. Also, please take care not to open or modify windows while a menu is open. This can yield unwanted effects, since the open menu window does a grab(), so that mouse events can be captured. This can result in the program appearing to hang. Although this has been fixed at least partially, there can still be some bad effects. See http://www.fltk.org/str.php?L1986 That said, I'd try if mvalue() is of some help for you. It returns the last menu item that was picked(), and I assume this is or can be the (parent ?) item that has been clicked to open the currently open menu item/window. However, I'm not at all sure about this, and you'd have to check if this is also usable if only the top level menu item has been opened, and also if this is really reset when the menu is dismissed - I don't know, but this is the best help I can give. Another way could be to use a callback that will be called when a menu is selected, but again I'm not sure if this will help. You'd probably have to track the open menu(s) yourself, and I also don't know if you'd get a callback when the menu gets closed.
