QThread:run() : Returning from this method will end the execution of the thread

Hi, Thanks for your answer.

A Returing (meaning 'return 0;' eg.) seems to be complicated under most circumstances.
Just to make sure, that I am right: when I call the run-function, the thread starts to work and with the exec(); it stays running? So what about quit() or exit()?
