[gtkmm] Correct way to wrap motif widget?

[Charlie Cosse <ccosse psl nmsu edu>]

Hi, i'm making the transition from LessTif -> Gtkmm and would like to
know how to use a libXm-based widget in a Gtkmm application?
The GtkSocket class discusses incorporating an X-window into gtk apps,
so thought that's probably the way, but discovered gtkmm before ever
writing test apps, and now i'm just gonna ask! Anyone know how?
Thanks again!


(it's a plotting widget that doesn't have anythingg close in Gtk, so would
really like a way)
