Pardon me, I said:
"I don't know what Qt signals are."

I'd say a slot is a callback. A signal is the designation of something
that will trigger callbacks.

1. What exactly is a signal. In hardware, an interrupt can be viewed as a

Forgive Steven for his off-topic reply. I assume he's trying to goad you
into having a more specific subject line. He knows darn well what PyQt,
even if he has no experience with it.
