Log:
2008-03-06 Thomas Thurman <tthurman gnome org>
Part three of the great prefs refactor, this time
dealing with string preferences. (This was the most
complicated part, and has been especially tested and
valground before committing. As ever, though, let us
know if you find a problem.)
* src/core/prefs.c (MetaStringPreference): new struct.
* src/core/prefs.c (update_*): replaced with *_handler
* src/core/prefs.c (meta_prefs_init): uses new string prefs
init; uses array of gconf dirs to monitor rather than
repeating code.
* src/core/prefs.c (handle_preference_init_enum): tidying
* src/core/prefs.c (change_notify): uses new string prefs
