title: <SOCKET>>::tuple': no overloaded function takes 3 arguments. in Qt visual studio 2019
body: <p>I have made a client and a server. In server I have done multi threading. Now I am making a UI for my server program using Qt in visual studio 2019. But now here in my server code after running it when I run my client the server program gives me an exception &quot; cannot send events to objects owned by another thread&quot;. I want to make a different thread in server for handling all the clients and my main thread will handle the GUI since the GUI freezes so I need a different thread to handle my clients. I have attached my server and client code below .  can anyone tell me what I am doing wrong here?</p>
