[Pyobjc-dev] Passing ObjectiveC pointers to PyObjC

[James T. <tra...@gm...>]

Hello,

I'm trying to augment my existing ObjectiveC application with some
embedded Python. I've got an embedded Python interpreter that can run
PyObjC, but what I would like to do is the following:

In my ObjectiveC application, I'd like to get a pointer to an object
(an NSString, for example):

NSString *tmpStr = [NSString stringWithString:@"Test"];

Then, I would like to pass this NSString pointer to a Python function,
so that I can use PyObjC to operate on the object in the normal PyObjC
fashion:

def handler(s):
    print "The length of the string is ", s.length()

I would try to call the Python handler() procedure like so:

PyObject* arg;          // tmpStr
PyObject* method;  // "handler"
PyObject_CallMethodObjArgs(_self , method, arg, NULL);

I don't know how to go about obtaining PyObject*s from the ObjectiveC types...

Is this even possible?

Thanks.
