added buttons to test moving/reordering groups.
2000-04-16 Damon Chaplin <damon@helixcode.com> * test-shortcut-bar.c: added buttons to test moving/reordering groups. * e-shortcut-bar.c (e_shortcut_bar_on_drag_end): new function to free the dragged name & URL when the drag is finished. * e-group-bar.c (e_group_bar_get_increment): fixed bug when distance was 0. Should just return 0. (e_group_bar_set_current_group_num): added animate option and finished. (e_group_bar_unmap): called e_group_bar_stop_all_animation(). (e_group_bar_reorder_group): finished. * e-icon-bar-text-item.[hc]: removed, since we now use EText. svn path=/trunk/; revision=2459
