How to connect signal-slog in second thread?

[anda_skoa]

So in my case, run() method of Worker class would have just one line of code to connect signal slot?

No.
As I wrote, this approach treats run() like main().
There is no slot to connect to unless you create an object that has such a slot.

After calling exec() on the thread, will the thread stay alive, that is, would it handle signal slot events?

Yes.

Am I still able to terminate this thread from the first one?

Yes, simply by calling the thread's quit() method.

Ok, I've solved it with a bit of trial and error. Here is a working sample:

No.
That still processes everything in the main thread.
Your worker thread does nothing, it jus sits there waiting for events that never come.
