gobject property notify question

["Robert Gibbs" <gibbsrc gmail com>]

Can anyone tell me why property notifications work only for properties that are readable?  This seems like an arbitrary restriction.

I want to get a callback whenever a writable only property gets set on an object instance that I have.  Is there any way to do this?

Thanks

From gobjectnotifyqueue.c

static inline void
g_object_notify_queue_add (GObject            *object,
                           GObjectNotifyQueue *nqueue,
                           GParamSpec         *pspec)
{
  if (pspec->flags & G_PARAM_READABLE)
    {

     ......
}
