[Qt-interest] QThread event loop running in main thread?

[Hannu Shemeikka]

Well,

Maybe you guys, Nokia or whoever is responsible, should update the 
documents. Especially the QThread-stuff. It's written there that "to 
create your own threads, subclass QThread and reimplement run()."

Someone should write a nice good tutorial on QThread and its proper 
usage. It would save a lot of time from everyone. And I don't mean a 
simple producer-worker example.

Little off-topic but hopefully nobody cares about it :)

I used to do things almost like the original poster is doing and things 
worked. Though I don't know why his doesn't work.
