Must be said: IANAL.
There's no way the QtCompany lawyers will allow you to relicense parts
of Qt as BSD code, so you can't copy the code into that file.
Copying Qt code parts to your own code is a very grey area and I wish
there would be some sort of guidelines from QtC about what they allow.
But I can understand why they don't do this - there are multiple and
very ugly cans of worms waiting for them if they would do it.
The best way to do this is usually to place the code in a separate
library with a very clear license.
