Py++ generates the wrong code in this situation.

This is how gccxml reports the class name.

No, I would call this a "challenge". The following is just an untested idea: 1. create the following class: class callback_wrapper_t{ callback_wrapper_t( boost::python::object callable ){ store it in the class} bool operator()( bool ){ call the function } } 2. create a wrapper bool createTimerWrapper( boost::int64_t interval, boost::python::object function, bool recurring = false ){ createTimer( interval, boost::function<bool>( callback_wrapper_t( function ) ), recurring ) } 3. Register the createTimerWrapper I think this could work. May be there is a better way. If you have a lot of functions like this and the idea works, I can help you to generate it with Py++. -- Roman Yakovenko C++ Python language binding http://www.language-binding.net/ _______________________________________________ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
