We do use something like reference counting to allow Window objects to
be
assigned. But that capability was a mistake - we wouldn't do it if
starting
over - so I won't try to describe it.

I started with a non-limited hierarchy that could be copied but found
that not all wxWidgets classes can be copied as the copy constructor is
private in certain objects, e.g. all wxWindow derived types. So, I now
have a limited hierarchy, even though certain objects need to be
copiable, e.g. wxEvent derived types.

Thanks,
Luke.
