Hm, this possibly is a problem: This file is licensed LGPLv2 only.
Qt is licensed under LGPLv3, as far as I know, so you cannot copy the code.

In an ideal world, you now would forget everything you have seen and write this code again :-)
In practice, the result often looks more or less the same.

So if you can claim the following code comes from you, then I think we are on the safe side...
