Fix for 46359, enable "Alt+Down Arrow" to show the popup for

2005-01-19  Harry Lu  <harry.lu@sun.com>

        Fix for 46359, enable "Alt+Down Arrow" to show the popup for
        e-combo-cell-editable.c.

        * e-combo-cell-editable.c: (show_popup): rewrite it to a more
        generic function.
        (button_clicked_cb): call the new show_popup function.
        (entry_key_press_event_cb): show popup if "Alt+Down Arrow".
        (ecce_grab_focus): new function.
        (ecce_class_init): add grab_focus handler so that the entry
        can get focus.
