2000-04-24 Damon Chaplin <damon@helixcode.com> * gui/Makefile.am: added new source files and pixmaps, and removed old source files, which can be deleted. * gui/e-week-view-titles-item.[hc]: * gui/e-week-view-main-item.[hc]: * gui/e-week-view-event-item.[hc]: * gui/e-week-view.[hc]: new files implementing the week/month views. * gui/yearview.xpm: * gui/monthview.xpm: * gui/weekview.xpm: * gui/workweekview.xpm: * gui/dayview.xpm: new pixmaps for the toolbar buttons. These aren't intended to be the final pixmaps. * gui/calendar-commands.c: added radio buttons to the toolbar to switch between the calendar views, and moved the am_pm_flag here so we can get rid of view-utils.c. * gui/gnome-cal.[hc]: made it a subclass of GtkVBox, rearranged the widgets into 2 notebooks, and added the selection_start_time and selection_end_time fields. * gui/goto.c: updated to use new selection time range. * gui/quick-view.c: added '#include <gtk/gtkwindow.h>' so it compiles. * gui/e-day-view.[hc]: changed the interface to support the new selection time range, got rid of a few debugging messages and changed a few bits. svn path=/trunk/; revision=2583
