Thanks a bunch! It's working now! :)
I first got the GtkCTreeRow from the node then its GtkCListRow
and the nset the data and callback function.
Now I see you can use a special function on gtk_ctree_* to set it
in one pass. I don't know why I missed that one earlier but thanks for
pointing that out!
