2003-06-30  Bolian Yin <bolian.yin@sun.com>

        Fixes #45328, #45329

        * gui/e-day-view.c (e_day_view_do_key_press): Do not process
        PageUp/PageDown, .. when the Alt key is pressed (give key binding
        set the chance).
        * gui/gnome-cal.h : define new enum type, GNOME_CAL_GOTO_DATE_TYPE.
        * gui/gnome-cal.c (gnome_calendar_class_init): define new signal
         "goto_date".  Add key bindings for "Alt+PageUp/PageDown",
         "Alt+Home/End".
        (gnome_calendar_goto_date): Impl. signal handler for "goto_date".
