Depends what you mean by efficient, I guess.  If you're looking at the
API documentation for e.g. Gtk::ComboBox::set_wrap_width() (just an
arbitrary example) at
http://library.gnome.org/devel/gtkmm/unstable/classGtk_1_1ComboBox.html#a320ba39253e225c63979b2d41342068c, you can scroll down to the bottom of that page and you'll notice the following:

"The documentation for this class was generated from the following file:
      * gtkmm/combobox.h
"

That should tell you which header file you need to include.

hope that helps
