How to create Python object in C/C++ extension by class name?

[Neil.Fang.CN]

Hello

I'm trying to write a C++ extension like this:

//-----------------------------------------------------------------------
// C++ code
class ActorBase
{...};

// export ActorBase to Python as a new type

class ActorManager
{
void addNewActor(const char* actorClassName)
{
?????
}
}

// export ActorManagerto Python as a new type
//-----------------------------------------------------------------------

The question is how to implement ActorManger::addNewActor(), I want
the class name can be a Python class which inherits the C++ class
ActorBase?

Thanks

Have you considered writing your extension in Cython?

http://cython.org/

It would allow you to use Python idioms for what you want to achieve.
