Hi Murray,

	Though you said to ignore this you make an important point :-)

	Right - so; the thing is that we provide a lot of interfaces, and we
also provide a set of standard C implementations. However - it seems to
me there are often two functions of the methods an object exposes -
those that are intended as it's public interface, and those that are
used to construct / manipulate it. The CORBA interface only provides
those public methods. It would / might be possible to provide another
'protected' sort of interface to allow construction of remote abstract
objects to do what you want - but really this is not desirable I think.

	Thus to implement a BonoboUIComponent you can sub-class the Bonobo
version [ which really just provides wrappers that allow NULL ev's [
mostly ] - and hold the UI component name as a constant ].

	Or ... you can implement a C++ version, that uses whatever slot /
signal mechanism you like to handle verb / id callbacks, and has a
thoroughly un-inhibited C++ implementation. Whether to re-implment or
wrap is your decision. For the UIContainer side it's more tough -
re-implementing that will be virtually impossible - but then as soon as
we touch the Gtk+ side, it becomes a bit of a C-Gtk+ API vs. CORBA
discontinuity which is hard to know how to handle.

	Does that help ? good question thought,

	Regards,

		Michael.
