Hi, I can't seem to get inheritance and virtual functions to work together in a simple python binding: #include using namespace boost::python; struct Base { virtual ~Base() { } void nonVirtualFunc() { } virtual void virtualFunc() { } }; struct Derived : public Base { ~Derived() { } void virtualFunc() { } }; struct BaseWrap: public Base, public wrapper<Base> { void virtualFunc() { if (override virtualFunc = this->get_override("virtualFunc")) virtualFunc(); else Base::virtualFunc(); } void default_virtualFunc() { this->Base::virtualFunc(); } }; BOOST_PYTHON_MODULE(test) { class_("__Base") .def("nonVirtualFunc", &Base::nonVirtualFunc) ; class_("Base") .def("virtualFunc", &Base::virtualFunc, &BaseWrap::default_virtualFunc) ; class_("Derived") .def("virtualFunc", &Derived::virtualFunc) ; } Now in my python interpreter:

...

...

import test dir(test.__Base) [<built-ins>, 'nonVirtualFunc'] dir(test.Base) [<built-ins>, 'virtualFunc'] dir(test.Derived) [<built-ins>, 'virtualFunc']

Without using BaseWrap to do the virtual functions:

...

...

dir(test.Derived) [<built-ins>, 'nonVirtualFunc', 'virtualFunc']

It seems that by using the boost python wrapper, I now lose any inherited functions, and the nonVirtualFunc does not get defined in the subclasses. I may be going about this in the wrong way, but is there a way of using inheritance and virtual functions together? Thanks, Dan
