GtkTreeView - Set user data to a row

Question

Is there a way to store user data on a single row in GtkTreeView? Like it's usually can be done on any widget with the function g_object_set_data(). I tried storing data on GtkTreeIter but it produces

segmentation fault error

The best way to do it I can think of is just to create an additional hidden column. Is it how it should be done?

Answer 1

Yes, a hidden column is how it should be done. (g_object_set_data() only works on GObject-derived types, and GtkTreeIter is not one.)
