    Qt Code:
    1. QString str("1234");
    2. QTextStream ts(&str);
    3. quint16 num = 0;
    4. ts >> num;

    I have a QLineEdit:
    Qt Code:
    1. QLineEdit *lePort = new QLineEdit();
    2. lePort->setText("3000");
    To copy to clipboard, switch view to plain text mode 

    In my tcpSocket I need to connect:
    Qt Code:
    1. QTcpSocket *tcpSocket = new QTcpSocket();
    2. tcpSocket->connectToHost(QHostAddress("127.0.0.1"), quint16(2000));
    To copy to clipboard, switch view to plain text mode 

    In stead of having the quint16(2000) I would like to have the value of lePort. I tried
    Qt Code:
    1. tcpSocket->connectToHost(QHostAddress("127.0.0.1"), QString::number(lePort->text()));
    To copy to clipboard, switch view to plain text mode 
    but it doesn't work.

    Actually i see that you want string - > int not int->string as i understad before.

    Try next
    Qt Code:
    1. tcpSocket->connectToHost(QHostAddress("127.0.0.1"),lePort->text().toShort());
    To copy to clipboard, switch view to plain text mode

    QString::number() makes a QString from a number.. read the docs first.
    Use QString::toInt(), QString::toUInt(), etc.
