making GtkTreeView look like GtkTree? and Setting colums diff. colors based on level?

[<shark centibyte org>]

I like how GtkTree looks, with the lines connecting parent nodes/rows to
child nodes/rows, and the slight indentation.  GtkTreeView has the
indendation but not the lines.  Does anyone know how to make GtkTreeView
look like GtkTree in that respect?
Also, is it possible to make all the first columns be red text, but only
if they are root-level rows?   As I understand it, GtkTreeView has you set
the CellRenderer by column only, with no regard to what level is being
rendered.
Thanks!
