Re: GtkTree, cell with toggle

[p s <tuxnduke welho com>]

Still a problem..

This row asserts:

gtk_tree_store_set(GTK_TREE_STORE( model ), &iter, column_number, value, 
-1 );

(moviecatalog:8356): GLib-GObject-WARNING **: invalid cast from 
`GtkTreeModelSort' to `GtkTreeStore'

(moviecatalog:8356): Gtk-CRITICAL **: file gtktreestore.c: line 1043 
(gtk_tree_store_set): assertion `GTK_IS_TREE_STORE (tree_store)' failed

(to remind I used :
GtkTreeModel * sort_model;
sort_model = gtk_tree_model_sort_new_with_model(GTK_TREE_MODEL(store));
when initially creating the table..)

Also tried:
gtk_tree_store_set_value (GTK_TREE_STORE( model ), &iter, 	 
column_number, value );

with equally bad outcome and same assert..


TIA,
P_s
