[Qt-interest] Qt examples licensing

[Denton Vis]

Hi everyone,
I started using a Qt example class as a building block for my own. After 
customizing and redoing a lot of stuff to my taste, the class little, if not 
nothing, in common with the original Qt source.

I was just wondering, if I can remove the Qt comment block at the beginning 
of the file and put the generic GPL open source comment block at the 
beginning. Or am I constrained to keep it there since I started from their 
code.

Thanks,

Denton
