Hello,
the docs for QThread says, to call exec() to start the thread's event loop.
My application needs queued connections, so I need to start this loop. But
something like that hangs forever:
run() {
exec();
}
QT doesn't provide an example with threads and an started event loop. For
example inserting a call to exec() in the run() method in the mandelbrot
example makes it hang forever too.
Do I have to implement an explicit event loop?

That's the correct thing to do: call exec().
You have to ask the event loop to quit, though. There's a quit() function.

I think the problem you are having is that unless you move the QThread
object to its own thread you cannot queue connections. Take a look at
http://lists.trolltech.com/qt-interest/2007-09/thread00073-0.html. I
threw a bit of sample code for what I do in one of the replies.
