Sorry for the delay in the answer, but yesterday I only send the answer

Sorry.

Yes, I know that, but,.... in the Dispatcher you are able to connect a
signal with parameters to it only once and that signal can be emitted as
many times as needed (always with the same parameters values).

Meanwhile, the in the Thread pool, each time a slot is sent, different
parameters values could be used.

Perhaps a message queue is needed to send slots with different
parameters values to main thread, and notify to main thread using a
signal in a Dispatcher?
