I haven't used GtkTreeView as a tree before, but when using it as a
list, you make the final field a G_TYPE_POINTER.  A G_TYPE_POINTER (as
opposed to, say, a G_TYPE_STRING) isn't displayed to the user - it is
only used for you to store and retrieve values.  I assume it works the
same way with a GtkTreeView tree.  Check out the GtkTreeStore functions
in the GTK+ docs as I believe that is what is needed to store and
retrieve the value of the G_TYPE_POINTER "field" by passing a gpointer
(a "void *") instead of a string that you see in the examples.

I hope this helps.  I don't remember much this functionality at the
moment, but if more comes back to me, I'll let you know :)
