	Sounds good to me - but for the fact that using GtkArgs in libbonobo
would add a Gtk+ dependency to a non-GUI library ;-) so we tend to use
GObject properties instead.

	So - now you need to use bonobo-arg.h's mapping methods to convert
GValue's to BonoboArg's. All the mappers are still there.

	I suggest that instead you use:

void
bonobo_property_bag_map_params    (BonoboPropertyBag   *pb,
				   GObject             *on_instance,
				   const GParamSpec   **pspecs,
				   guint                n_params);

	Which will allow you to map a selected set of parameters.

	So; for reasons I don't understand, the porting guide fails to mention
libbonobo[ui]/changes.txt which details the changes from the last
versions. This contains:

bonobo-property-bag.[ch]:
	bonobo_property_bag_add_gtk_args is now called
	bonobo_property_bag_map_params and changed sig.
bonobo-arg.[ch]:
	bonobo_arg_from/to_gtk -> bonobo_arg_from/to_gvalue
	bonobo_arg_type_to/from_gtk -> bonobo_arg_type_to/from_gtype

	It's pretty stupid that these files are not mentioned; someone needs
moaning at, but I forget whom maintains the porting guides and have no
time just now.

	Your sample app looks ok; but when I ported to Gnome 2.2 I decided
(having seen much cut and paste of horribly written sample code) to have
no samples that are dubious ;-) OTOH, I'd be extremely happy to have
something based on this - turned into something that is generic, and not
Abi-word specific, in CVS.

	I was hoping glade-2 would provide a nice place to test out this sort
of thing; but for various reasons it isn't.

	Regards,

		Michael.
