adding new signal in new class

[Yasushi Shoji <yashi yashi com>]

hi all,

Is there any Object Oriented Programming Language binding for Gtk+
that allows programmer to add new signal in newly created class?

e.g. create new subclass of HBox and add new signal called "new_sig".

if not, is it possible to do so?  Just a quick search in gtk-list
archive gave me an idea that gtk_object_class_add_signals() is the
one. but that function needs GtkObjectClass* as first argument...

hope some one help me out.

thanks.
