[Pyobjc-dev] dynamic update of metadata for CF types

[Orestis M. <or...@or...>]

Hello,

I'm struggling in using registerCFSignature. What I want is to use  
CGColorGetComponents that returns a variable length array of floats. I  
think that this particular case is fixed in trunk, given that I found  
a testcase for it. However, I have to use the stock PyObjC that comes  
with Leopard for now, and I'm looking for ways I could update that  
signature at runtime.

The closest I got was:

objc.registerCFSignature('CGColorGetComponents', '[3f]',  
CGColorGetTypeID())

Unfortunately, I still get a PyObjCPointer and the accompanying error  
message.

Is there any way of doing what I want to do?

Thanks,
Orestis
