Hello,
I'm migrate my aplication from GTK 1.2 to 2.10. So I try to use GtkTreeStore and GtkTreeView. The fist task is to show the file system hierarchy (and I want to filter this list, but it will be a second question). When the user choose to expand one directory, I must add a lot of rows. To preserve times, i try to detach the model from the tree, and to disable the sort. The result is that it goes faster but i got this error message Gtk_CRITICAL ** : gtk_tree_store_sort : assertion tree_store->default_sort_func != NULL failed Gtk_CRITICAL ** : gtk_tree_store_sort_iter_changed : assertion tree_store->default_sort_func != NULL failed Is there an other way to disable the sort ? Thank you ------------------------------------------------------------------------ ------------------------------------------------------------------------ ----------------- // creating the interface GtkTreeStore *p_TreeStore = gtk_tree_store_new(1, G_TYPE_STRING); GtkTreeSortable *p_Sortable = GTK_TREE_SORTABLE(p_TreeStore), GtkTreeView *p_TreeView = gtk_tree_new_with_model (GTK_TREE_MODEL(p_TreeStore)); gtk_tree_sortable_set_default_sort_func(p_Sortable, my_sort_function, GINT_TO_POINTER(0), NULL); ...
