[C++-sig] Re : Re : boost::python: C++/Python function overload issue

Thank you very much.
I knew the link already but it made me read my code again and realize that I forgot to reflect the overloaded functions with boost::python.

Does this (  http://www.boost.org/doc/libs/1_49_0/libs/python/doc/tutorial/doc/html/python/exposing.html  ) answer your question? specifically "Class Virtual Functions".
