QTcpServer listens on a different port than specified

[Idodoqdo]

Hello, I am writing a simple client server application using QTcpServer and doing the following

Server::Server()
{
    quint16 port = quint16(2323);
    if (listen(QHostAddress::Any), port) {
        qDebug() << "start" << this->isListening() << this->serverAddress() << this->serverPort();
    } else {
        qDebug() << "error";
    }
}

But it doesn't listen to the specified port and

this->serverPort();

displays a different port each time. Port 2323 is not busy

Because you've put port in the wrong position.
You didn't even pass it to the listen funtion, so it will take port=0 as the default parameter, that means choosing a port automatically
It should be

listen(QHostAddress::Any, port)

I don't quite understand you. I have exactly the same line

@Idodoqdo No, you do not :) Please look carefully

@Bonnie

if (listen(QHostAddress::Any), port) {

@Idodoqdo Still have not found your mistake :)

if (listen(QHostAddress::Any), port) {

Wrong right bracket position, so wrong port position...

Thanks a lot
