Made a NULL callback just mean to not call back.
2000-05-07 Christopher James Lahey <clahey@helixcode.com>
* backend/ebook/e-book.c: Made a NULL callback just mean to not
call back.
* backend/ebook/e-card-simple.c, backend/ebook/e-card-simple.h:
Reordered fields. Added a get_const function to get a constant
string that persists until the simple is destroyed.
* gui/component/Makefile.am: Added e-addressbook-model.c and
e-addressbook-model.h and all of the libraries and includes that
they are dependent on.
* gui/component/addressbook-factory.c: Initialize e cursors.
* gui/component/addressbook.c: Added inactive code to display an
ETable view of the addressbook.
* gui/component/e-addressbook-model.c,
gui/component/e-addressbook-model.h: New files to implement an
ETable model with a EBook back end.
