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. svn path=/trunk/; revision=2845
