hi, i'd like to do something like this: -------------- CUT HERE -------------- #include using namespace boost::python; struct A { void f() { /* do something */ } }; A a; BOOST_PYTHON_MODULE(hello) { class_<A>("A") .def("f", &A::f) ; def_readwrite("a", a); } -------------- CUT HERE -------------- i don't see how to do it with boost. any hint for a poor newbie? thanks dom -----[ Domenico Andreoli, aka cavok --[ http://filibusta.crema.unimi.it/~cavok/gpgkey.asc ---[ 3A0F 2F80 F79C 678A 8936 4FEE 0677 9033 A20E BC50
