2001-01-30 Havoc Pennington <hp@redhat.com> * gtk/gtkliststore.c (gtk_list_store_insert_before): fix bug in here where prev pointer was set to the wrong thing * gtk/gtktreemodel.c (gtk_tree_path_is_ancestor): new function (gtk_tree_path_is_descendant): new function * gtk/gtkliststore.c (gtk_list_store_iter_n_children): return cached length (gtk_list_store_get_iter): don't modify iter if we can't get the path. * gtk/gtkliststore.h (struct _GtkListStore): cache the length * gtk/gtktreednd.h: add virtual function row_drop_possible() to GtkTreeDragDest * gtk/gtktreestore.c (copy_node_data): fix varargs type error that was causing segfault * gtk/gtktreedatalist.c (_gtk_tree_data_list_node_copy): set next pointer to NULL * gtk/gtktreestore.c (gtk_tree_store_append): fix memleak * gtk/gtkliststore.c (gtk_list_store_iter_next): don't modify iter on returning FALSE (gtk_list_store_iter_children): ditto (gtk_list_store_iter_nth_child): ditto (gtk_list_store_iter_nth_child): ditto (gtk_list_store_iter_parent): ditto * gtk/gtktreestore.c (gtk_tree_store_get_path): g_return_if_fail on iter->user_data != NULL instead of silently accepting it. (gtk_tree_store_iter_next): ditto. Also, don't modify iter unless we are returning TRUE. (gtk_tree_store_iter_children): ditto (gtk_tree_store_iter_nth_child): ditto (gtk_tree_store_iter_parent): ditto (gtk_tree_store_insert): remove handling of parent->user_data == NULL, replace with parent == NULL * gtk/gtktreemodel.c (inserted_callback): put some fixes in here, and a comment explaining things * gtk/gtktreestore.c: add GtkTreeDragSource/GtkTreeDragDest interface support to GtkTreeStore. * gtk/gtktreemodel.c (gtk_tree_path_prev): didn't properly return FALSE if no prev, fix * gtk/gtktreeview.c (set_source_row): use a row reference (set_dest_row): use a row reference
