[Pyrex] callback

[Bryan Weingarten]

i currently have a callback similar to the cheese demo.  but i have a
problem i hope someone can help me resolve.


the following code works correctly... it's basically the "cheese" code:

class Play:
    def status_callback(self, callback):
        set_status_callback(self.ctx, _callback_wrapper, <void*>callback)

cdef int _callback_wrapper(void *callback, long sec, long msec):
    return (<object>callback)(sec, msec)


my problem is that the i need user data to be passed into status_callback
which gets passed back to the python callback.  the "cheese" way of doing
this is to cast the python callback function to a void* and pass it into the
user data field of the c function.  unfortunately, this takes up the one and
only user data field and doesn't allow for the python user to pass in user
data.  i tried to add the _callback_wrapper as a method of the class so i
could save the data as instance data, but pyrex complained about that... so
i'm at a loss now...  can someone help me?

thanks,

bryan
