connectToHost() resets local port number specified by bind

hello!

I try to connect to a server as tcp from client and bind(enter the port for the client), but after I connect to the host (used connecttoHost() method ) in the client
the port changed.
QT client:

Code:

---

Socket->bind(QHostAddress("localhost"),2555);
 
            Socket->connectToHost(QHostAddress::LocalHost,1458);

---

there is any method or approach to make the port for the client fix ??

The client always uses a dynamically chosen TCP port. Why would you want to fix it?

I'm implementing chat application and I want from client to be able to enter the port for him from textedit

Why would a user want that? It is entirely irrelevant to the functionality they consume (chatting).

Cheers,

You're right.
However,I need the client enter port to bind UDP connect,but I used the tcp to send the online client.It was my error I tried used the same port for tcp_socket and udp_socket.
thanks a lot!:)
