Hi. I'm trying to find out the diffrence between normal classes and classes derived from built-in types. (Which is causing me trouble trying to instantiate a class using C API calls)
>>> class A: ... pass ... >>> class B(dict): ... pass ... >>> type(A) <type 'classobj'> >>> type(B) <type 'type'> >>> When I have a handle to A as a PyObject, I can create an instance using PyInstance_New(). When I have a handle to B, this does not work as the function wants a class PyObject. I found that the API function PyType_GenericNew() can create something from the B type, but it does not call any constructors. (using the 'dict' here is an example. In my case, I'm using a self-defined type I'm using as an API into the C++ part of the software.) Anyone know how an object could be instantiated using a handle to B? thanks, Achim Dahlhoff. -- http://mail.python.org/mailman/listinfo/python-list
