Re: ComboBox Background Colour

[Jonathon Jongsma <jonathon jongsma gmail com>]

As Pierre said, Color is in Gdk.

Also, Gdk::colormap should be Gdk::Colormap and it can't be
instantitated directly since the constructor is protected.  You'll
need to so something like:
Glib::RefPtr<Gdk::Colormap> cm = Gdk::Colormap::get_system();
