Andrey, you are right if I'm not using the signals/slots, but calling it directly causes it to run in current thread. It works just fine now, thanks.
Denis, I did check out QtConcurrent::run(), but since I return void from the function and I have to call the function multiple times possibly in the same thread so that I can append to QXmlStreamReader's data, I think it is easier to just use QThread in this case. However thank you for your input, I'm sure I will make use of QtConcurrent in the QFuture.
