That's just wrong.

Gtk+ must be able to solve the case when you have multiple menubars.
Evolution for instance has at least two: one in the shell
and one in the composer.

We're missing some API which each application can call to set the
current menu bar. Also remember that you need to solve the parent problem.
In Win32/X11 menus are packed to a vbox, but on Mac OS X the menus needs
to be populated differently.

A very hackish way would be to connect on parent::notify in GtkMenuBar and
force the menubar to be invisible, traverse all the children and add them
using the Cocoa API. Not perfect, but it'll allow you to get going and the
code to map GtkMenuItem to Cocoa items needs to be written anyway.
