GtkTreeView drag-n-drop



  I would like to enable drag-n-drop in a GtkTreeView widget (gtk2), but
have no idea of how to do it. It seems to involve interfaces. I don't
know how to use interfaces, and there is practically no documentation
about it. :-(
  Is there any example out there about GtkTreeView drag-n-drop or
interfaces?
  Thanks in advance.
