2007-04-02 Rodrigo Moya <rodrigo@gnome-db.org> * gnome-settings-daemon.c (gnome_settings_daemon_new): return NULL when there is an error, not exit(), so that we do proper cleanup. Remove code to register GConf callbacks, that is done in utils.c. (gnome_settings_daemon_get_conf_client, gnome_settings_daemon_register_callback, gnome_settings_daemon_spawn_with_input, gnome_settings_daemon_get_invisible, gnome_settings_daemon_delayed_show_dialog): removed from the GnomeSettingsDaemon interface. * utils.c (gnome_settings_get_config_client, gnome_settings_get_invisible, gnome_settings_register_config_callback, gnome_settings_spawn_with_input, gnome_settings_delayed_show_dialog): moved from GnomeSettingsDaemon interface. * factory.c (main): check return value from gnome_settings_daemon(). * *.c: adapted to changes in function names. * Makefile.am: put source files in alphabetical order. svn path=/trunk/; revision=7434
