[PyKDE] Help:Anybody give me an example how to use sip.voidptr object?

[sfang]

Hello, Guys,
I got a sip.voidptr through qt.QImage.bits(), and I read doc that sip.voidptr 
object is only useful if passed to another Python module. I try to pass to 
other python module like  PIL to get those pixel data and fail, Anyone has the 
experienc of use sip.voidptr? Could you tell me how to use it or a piece code 
to show me how to use that kind of object, I am realy need such a hint. I try 
a lot of way to understand how to use it. 
Thank you very much!
