How do I use custom Paint Engine/Device globally?
If I write my own implementation of QPaintEngine/QPaintDevice, how can I make all widgets use them in my application? For example, if I want to render all Qt graphics through a 3rd party library.
I would advise asking this directly on the interest mailing list (don't forget to subscribe first) It's an unusual question and you'll find Qt's developers/maintainers there (this forum is more user oriented)
Thank you, I will try there.
