1) when i connect the newClientConnectedSig() signal inside listenerThread.cpp and run a slot it works fine. so emiting a signal from listenerThread.cpp has no problem.

2) but when connect is inside of serverstartThread as shown in the snipets it doesn't receive the signal from listenerThread().

**is this because of the Thread inside of a thread?**

What I have tried:
