        * widgets/e-text/e-text.c, widgets/e-text/e-text.h: Added the
        ability to access the text event processor.

2000-03-13  Christopher James Lahey  <clahey@helixcode.com>

        * addressbook/demo/addressbook-widget.c: Made the addressbook
        component look in the users home directory for the addressbook.xml
        file.
