fix bug in here where prev pointer was set to the wrong thing
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
