Reading and rereading a file with QXmlStreamReader

[wysota]

I don't think Qt people would make such mistake by not even providing a virtual destructor if they think people could use it as a based class, of course C++ doesn't stop people from doing it...unlike the keyword "final" in java...

Correct me if I'm wrong but virtual destructor is needed only if you have some other methods declared as virtual. Lack of virtual methods doesn't prevent you from adding new methods.
