GtkTreeView row colors

[Roland Roberts <roland astrofoto org>]

I'm having trouble figuring out how to change the font color/weight for 
each row individually in my GtkTreeView.  I'm using a GtkListStore and 
want the rows color coded depending on the data used to fill the row.  
Actually, I want color coding based on data which is *not* actually 
displayed (textually) in the view.  So I know the colors when I fill the 
list with data.

I found this message 
http://www.mail-archive.com/gtk-list gnome org/msg25005.html that refers 
to a per-cell callback.  I don't want a per-cell callback and I can't 
tell, per-cell what color something should be.  Only one color contains 
the information needed to even look up the color information.

Here's more detail:  I have an application that probes to detect a set 
of devices connected to the computer.  Some of those have open 
connections, some do not.  The ones with open connections should be 
colored one way, those without another.

Can someone point me in the right direction here?

TIA,

roland
