Help about GtkTreeViewColumn

[zz excite it]

Hi,
I'm developing an app that uses a mysql database so I'm doing a lot of work with tree views.
Now I'm wondering if it is possible to align the text in the cells of the  single columns of the tree view
in the same way you can do it with the headers.

gtk_tree_view_column_set_alignment((GtkTreeViewColumn *)gtk_tree_view_get_column ((GtkTreeView *)tot_list, 
0), 0.0);

I've RTFM but have not found a way to do this so far  :(
Hints are wellcome.

Thanks in advance.

Ciao,
Tito
