QTcpSocket in different classes?

Question

Qt

Hello, I'm new. I want to connect via qtcpsoket to the server. The problem is that I'm connecting, but I need to use this connection in other classes.
My task is to connect, wait for data to be sent from the mainwindow (login and password), after sending, receive a response (0 or 1), enter the confirmation code in another window (if the response was 1).
Tell me please. I’ve been stuck on this for two weeks, I can’t figure it out. There is no information on the Internet. It is advisable to explain with an approximate code)

Answer 1

Communication over the network should be handled by one class. You can pass data to other classes using the signal/slot mechanism.
Those. in a class that deals with network communication, you create a signal, and in another you associate it with a slot. At the right time, pull the signal with the right data.
