Hrm, that happens when you write in a hurry...

The funtion I am using is returning SPINKIT_DATA(Structure): and I find 
that this is not easy to use in python and so I "convert" it into 
SpinkitPyData and return() this to have easier acces to the results.

def SpinKitReadNonBlocking(self,data):
         "Read Immediate"
         datac=SPINKIT_DATA()
         if 
windll.spinkit.SpinKitReadImmediate(self.Handle,pointer(datac)):
             data.Device=self.Handle
             i=0
             for spin in datac.Spins:
                 data.Spins[i]=spin
                 i=i+1
             i=0
             for button in datac.Buttons:
                 data.Buttons[i]=button
                 i=i+1
             return(True)
         else:
             return(False)


What I am asking is, if there is a more elegant way to convert the 
SPINKIT_DATA(Structure) into something more pythonesque like my 
SpinkitPyData which I think is a nice representation and easy to access 
inside python.

Hope this makes it more clear?

Carsten
