there must be a simple solution, but i just can't see it...
i'm using some library code which is calling a callback function i
declared in my class interface.
now my problem is that the callback function, which is a c-function,
doesn't even know self.
i need to declare the callback as a c function, but i want the
callback function to know about the object.
(the framework sends strings to my callback function, and i want to
send them to a textView object.
but i don't have access to the textView object in the callback
function.)
