How to convert from QString to quint16 ?

How do I convert from QString to quint16 ?

[zlatko]

QString::number doesnt help?

[jpn]

QString str("1234");
QTextStream ts(&str);
quint16 num = 0;
ts >> num;

I have a QLineEdit:


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


In my tcpSocket I need to connect:


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


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()));

but it doesn't work.

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

Try next


tcpSocket->connectToHost(QHostAddress("127.0.0.1"),lePort->text().toShort());

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