Well, as you've probably noticed the focus does move if the user clicks
the mouse to select a row. The code that does that, from clist's button
press handler:

 if (row != clist->focus_row)
                {
                  if (GTK_WIDGET_HAS_FOCUS(widget))
                    {
                      gtk_clist_draw_focus (widget);
                      clist->focus_row = row;
                      gtk_clist_draw_focus (widget);
                    }
                  else
                    clist->focus_row = row;
                }

I think it would certainly work to do this, but it is relying on the
widget's internals so you wouldn't be able to complain if it broke in
future Gtk versions. 

However, I see no way to do it using the exported API. Probably a patch to
export the API, or perhaps to make gtk_clist_select_row() also move the
focus, would be a reasonable thing for Gtk 1.4 if you want to submit such
a patch. 

Oh, gtk_clist_draw_focus isn't exported so you'd need to use
gtk_widget_draw_focus() instead. That should end up invoking
gtk_clist_draw_focus.

You're doomed here - GtkText sucks, and one of the ways in which it sucks
is that it doesn't scroll horizontally. It's supposed to be rewritten for
1.4, FWIW.
