Essentially, what you need to do is pass a Python object to call_method (boost::python::object or PyObject *) that already contains your C++ object. In order to get one, you need need to tell Boost.Python to construct A and B with what it calls a "back reference". Your C++ constructors will be given a PyObject* by boost.python, pointing to the Python objects the C++ object will be wrapped in, and you can then store those as data members and pass the PyObject * to call_method. You can find more information in the Boost.Python reference docs on class_, especially the "HeldType Semantics" section.
I did checked the docs, but I think I don't get how should it be done in my case. What they talk about (as well as in the provided example) They let the user to create Python classes derived from C++ classes and launchind virtual Python function. Would ou mind providing a sample piece of code how should it be done to wrap my C++ object into PyObject* ? Thanks in advance.
By the way, the call policies on your "gen" function should be return_value_policy<manage_new_object>, not return_internal_reference<>; the latter is for returning data members of wrapped classes and other things that are owned by another existing wrapped object.
Good point, thanks! -- regards Marek Denis _______________________________________________ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
