You might need to #include a gtk header. gtk.h would get you everything you
need.

You should probably check the result of get_frame() for null.
e.g.
Glib::RefPtr<Gdk::Window> refWindow = get_frame();
if(refWindow)
  ... GDK_WINDOW_XID( refWindow ->gobj() );

However, I've never heard of get_frame(). I would have tried get_window()
first. But I never do this stuff.
