    The rdp says :

"Signals are used by everyone, but they are only created on a per
class basis-- so you should call call gtk_signal_new() unless you
are writing a new GtkObject type. However, if you want to make
a new signal for an existing type, you may use
gtk_object_class_user_signal_new() to create a signal that
doesn't correspond to a class's builtin methods. "

    You'll have to provide your own code in order to emit the signal
    when you want (jus do something like :

    gtk_signal_emit(
                            my_gtk_object_p, /* object to which the signal
apply */
                            my_new_signal_id, /* got it when you created the
signal */
                            ... /* any other relevant parameters */
                            );

    Hope it helps,

        Emmanuel
