I believe you can pattern this class after dataobject.t. It seems that
wxpp supports an "abstract" keyword for methods, along with an ABSTRACT
keyword for the class declaration. I believe these will allow you to
solve the problem you are seeing. You will need to implement stubs of
the virtual methods, and it will be up to the ruby developer to override
those implementations with their own "real" implementations in ruby.
Hope this helps.
