Just by chance I've been trying to do this as well.  I wanted to store a
G_OBJECT in the GtkListStore, and display some info contained within the
object in the GtkTreeView.

I ended up writing a test program that uses the solution Harring
Figueiredo suggested in a previous email.  I've packaged the code up and
put it on the web if you want to take a look:

Note that this is proof of concept code, and as such has no comments and
probably isn't the optimal solution, but it does illustrate the point.
