added guint ref_count to iCalObject struct, and ical_object_ref/unref()
2000-05-06 Damon Chaplin <damon@helixcode.com> * cal-util/calobj.[hc]: added guint ref_count to iCalObject struct, and ical_object_ref/unref() functions. I've updated all the gui/ stuff to use ref_counts but I haven't touched the pcs/ stuff. Maybe just using ical_object_destroy() is OK there. * gui/gncal-todo.c: * gui/calendar-commands.c: * gui/eventedit.c: * gui/e-week-view.c: * gui/e-day-view.c: use refcounting for iCalObjects. * gui/e-day-view-main-item.c: * gui/e-day-view-top-item.c: * gui/e-day-view.c: try not to ever draw outside the event, even when the event is very small. 2000-05-05 Damon Chaplin <damon@helixcode.com> * gui/e-day-view.c: don't allow recurring events to be resized or dragged, and don't show the resize/drag cursors. Actually it may be better to let the user do the resize/drag and then ask them what they want to do - change the single occurrence or the entire series. * gui/e-day-view-time-item.c (e_day_view_time_item_show_popup_menu): use e_auto_kill_popup_menu_on_hide() to destroy the popup menu. * gui/popup-menu.c: include e-gui-utils.h svn path=/trunk/; revision=2823
