But when trying to run
import doh class MyCallback(doh.Callback): def execute(self, t): print t return 1 m = MyCallback() t = doh.Thing() t.setCallback(m) t.update() i'm getting Traceback (most recent call last): File "notopythonconverter.py", line 12, in t.update() TypeError: No topython (by-value) converter found for C++ type: Thing". And I fail to see why...
Mu guess: you need to use boost::python::register_ptr_to_python< Thin >(); ( http://www.boost.org/doc/libs/1_37_0/libs/python/doc/v2/register_ptr_to_python.html )
I have more or less complete example, which exports custom pointer class and its usage to Python: http://www.language-binding.net/pyplusplus/troubleshooting_guide/smart_ptrs/smart_ptrs.html
