You are mixing design patterns here. You say you wan to use signals/slots 
across threads - this demands an event loop to be running. However, your run() 
function in your example here is written in a blocking manner. Why do you need 
to use a slot in this thread? Why can't you just call QThread::start()?

It might help if you could provide a small example (e.g. the main function and 
two thread classes) or some more detail of what you are trying to do.
