I see now from the email's subject that you are talking about
libgnomecanvasmm and Gnome::Canvas::Group:
http://www.gtkmm.org/gnomemm2/reference/html/classGnome_1_1Canvas_1_1Group.html
which wraps
http://developer.gnome.org/doc/API/2.0/libgnomecanvas/libgnomecanvas-gnomecanvasgroup.html
I was confused by the different email subject that you used in the 1st
copy of your message.

I'm not sure that those GnomeCanvasGroup struct fields are public, but
you can always use gobj() to get the underlying GnomeCanvasGroup* from
the Gnome::Canvas::Group. Then you can do whatever you want with it,
maybe calling Glib::wrap() on the GList items.

If you want this wrapped in a future libgnomecanvasmm then you should
submit a bugzilla bug:
