added changed flags and added calls to a new function
2000-12-11 Damon Chaplin <damon@helixcode.com> * gui/event-editor.c: added changed flags and added calls to a new function event_editor_set_changed() to set & reset this flag. Added prompt_to_save_changed() which is called when the user selects File/Close or the window's close button. Fixed the 'All day event' toggle button. Made the 'Alarm' page sensitive as appropriate when filling widgets. (Though note that the alarm widgets are not being set yet.) * gui/dialogs/task-editor.c: added changed flag as above. * gui/event-editor-dialog.glade: used good names for all the classification radio buttons so we can access them in the code. * gui/event-editor.c (init_widgets): use the "show week numbers" config option in the recurrence preview calendar. * gui/e-day-view.c (e_day_view_update_event_label): use 9:00 instead of 09:00 in the main view, as we do everywhere else now. It means the times won't line up, but they are easier to read which I think is better. Added support for Page Up/Down, though I think it should move the selection rather than just scroll the canvas. * cal-util/cal-recur.c (generate_instances_for_chunk): removed the end parameter since we should be using the chunk end time now. Added single_rule parameter for when we are generating the occurrences of a single RRULE, in which case the event's start date is not included in the occurrences output (unless it results from the RRULE expansion). Both of these fix problems when using COUNT. * gui/gnome-cal.c (gnome_calendar_on_date_navigator_selection_changed): fixed bug when checking if the new start day starts on the week start day. If you select a complete week it should now show the Week view. svn path=/trunk/; revision=6896
