new files implementing a simple model for the shortcuts, so we can have
2000-07-16 Damon Chaplin <damon@helixcode.com> * e-shortcut-model.[hc]: new files implementing a simple model for the shortcuts, so we can have multiple views. * Makefile.am (libshortcut_bar_a_SOURCES): added e-shortcut-model.[hc] * e-shortcut-bar.[hc]: updated to use the model. * e-icon-bar.c (e_icon_bar_item_pressed): set mouse_over_item_num as well as pressed_item_num to fix bug. svn path=/trunk/; revision=4186
