[Interest] In-App purchase for the Mac App Store

[norulez at me.com]

Hello,

does anyone got it to work and could give me a hint on how to start? I saw an example on http://developer.apple.com but I don't know how to combine C++/Qt with the Objective-C/C++.
I want to use the Store Kit API with an Ui designed in Qt. 

I also read that Qt provides a mechanism for In-App purchases, but I think this is only for android, isn't it?

Could someone please give me a hint.

Thanks in advance

Best Regards
