How to convert from QString to quint16 ?

[probine]

I have a QLineEdit:

QLineEdit *lePort = new QLineEdit();
lePort->setText("3000");

QLineEdit *lePort = new QLineEdit();
lePort->setText("3000");

To copy to clipboard, switch view to plain text mode 

In my tcpSocket I need to connect:

QTcpSocket *tcpSocket = new QTcpSocket();
tcpSocket->connectToHost(QHostAddress("127.0.0.1"), quint16(2000));

QTcpSocket *tcpSocket = new QTcpSocket();
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

tcpSocket->connectToHost(QHostAddress("127.0.0.1"), QString::number(lePort->text()));

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.
