It's surprisingly simple, it turns out. First, you have to tag the OSG smart pointer type, as follows: ------------------- #ifndef REF_PTR_TRAIT_ #define REF_PTR_TRAIT_ #include <boost/python.hpp> #include <osg/ref_ptr> namespace boost { namespace python { template <class T> struct pointee< osg::ref_ptr<T> > { typedef T type; }; }} #endif ------------------- Then, in a BOOST_PYTHON_MODULE, you can write: class_<Node, ref_ptr<Node> >("Node", init<>()) ; You can of course add as many of the Node class's methods as desired.

What is wrong with the following code? I suspect I'm doing something silly, and I suspect the answer is obvious.
#include <osg/Node> #include <osg/ref_ptr>
#include <boost/python.hpp> #include <boost/python/pointee.hpp>
using namespace osg; typedef ref_ptr<Node> NodePtr;
using namespace boost::python;
BOOST_PYTHON_MODULE(NodePtr) { class_<NodePtr, pointee<NodePtr> >("NodePtr") ; }
Boost.Python knows Boost and TR1 smart pointers, not any others. If you are using any others (ref_ptr in this case I gather) then you need to make Boost.Python aware of it, I am not sure how, reading through the code might reveal how. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org
