Fri Jun 15 18:53:48 2001 Jonathan Blandford <jrb@redhat.com> * gtk/gtktreesortable.c (gtk_tree_sortable_set_sort_func): Rename gtk_tree_sortable_sort_column_id_set_func. It's much shorter now. * gtk/gtktreeview.c (gtk_tree_view_sort_iter_changed): WOOO!!! Now I can really reorder/sort all Store widgets. treesorttest seems to just work now. * gtk/gtklistview.c (gtk_list_store_iter_changed): Whoops. testtreesort worked through a big coincidence all this time. * gtk/gtkrbtree.c (_gtk_rbtree_reorder): Nasty bug fix in nasty code. * tests/testtreecolumns.c: Big 'ol warning at the top letting people know that this code should never ever ever be copied. HA! While everyone else was busy flaming eash other over configuration engines, I secretly got sorting completely working with store widgets and GtkTreeView. GtkTreeModelSort, here I come!!!!!
