Typically for a single row, you would do something like:
list_store.EmitRowChanged (path, iter);
And that would trigger the TreeView to refresh that row. For updating
*every* row, as a fallback you could at least loop the store and emit
the row changed event.
Alternately, a treeview.QueueDraw (); might be sufficient to cause the
whole Gtk.TreeView to redraw, although that's fairly "brute force"
