If speed of class creation is important (as it is for us). suggest to call type directly rather then evaluating a string every time and executing it - this is one way.

               /* always use O not N when calling, N causes refcount errors */ newclass = PyObject_CallFunction((PyObject *)&PyType_Type, (char *)"s(O) {sss()}", idname, py_base_class, "__module__", "bpy.types", "__slots__");

which is like doing this in python...

 type(idname, (py_base_class, ), dict(__module__="bpy.types", __slots__=()))

Campbell,

Thanks for the hint. It's good to know how the type() should be called from C.
