Here is my code :
GtkTreeModel *filter_model;
filter_model=gtk_tree_model_filter_new
(GTK_TREE_MODEL(store_ori),
NULL);
GtkTreeModelFilter *filter;
gtk_tree_model_filter_clear_cache(filter);
gtk_tree_view_set_model (GTK_TREE_VIEW(tree_view),
GTK_TREE_MODEL (filter_model));
...........
gtk_tree_model_filter_set_visible_column
(GTK_TREE_MODEL_FILTER(filter),7);
..........
(store_ori is a liststore)
gcc complains about filter not initialised.. ok but how to initialize it ?
