1999-01-30 Miguel de Icaza <miguel@nuclecu.unam.mx> * view-utils.c (view_utils_draw_events): Improve this draw routine. Now it can split the text in lines and fit as many events as possible. (nicetime): Return strings without spaces at the beginning. * gncal-day-view.c (gncal_day_view_expose): Move clip-clear operation here. svn path=/trunk/; revision=637
