but I want the description to be scaled to 0.7 of others rows.

hm, I don't want the arrow, if it will not be used. so I will create
another row for each user in the same parent.

I have a callback to GtkTreeSelection of this treeview, but which is of
type
void
on_treeview_select_row(GtkTreeSelection *selection,
                        gpointer user_data)

so, what to do now, if the type of return is void ?
