1998-04-02 Federico Mena Quintero <federico@nuclecu.unam.mx> * gncal-full-day.c: New full-day widget. It is still a work in progress. It will be similar to M$ Schedule's nifty full day view widget, but with Gtk's elegance :-) * Makefile.am (gnomecal_SOURCES): Added gncal-full-day.[ch] to the sources. svn path=/trunk/; revision=99
