Yes, the menu is a toplevel window in its own right, so it doesn't
have a parent. 

You can get at the parent menubar this way:

        GTK_MENU_SHELL (menu)->parent_menu_shell

but see below for a better way.

The usual way to pass data to a callback is to pass it at signal
connection time:

   g_signal_connect (menu_item, "activated", 
                     G_CALLBACK (on_about_cb),
                     main_window);

The main window will then be passed as "data" in the on_about_cb
function. I am not sure you can do this when adding event handlers
through glade, so you'll have to not do that.

Instead use libglade and manually connec whatever signal connections
you need.
