How to use __LINE__ macro as QString parameter ?

[AnneRanch]

This is driving me nuts - how use LINE macro (int) as QString parameter ?
The compiler likes it but the result is wrong.

    QString label = QString(__LINE__ );   //current code line 
    ui->chat_2->append(label);  //  no good

QString label = QString(LINE ); //current code line

use QString::number
QString label = QString::number(__LINE__ );

P.S. This thread is about how to use a Qt-specific class (QString), so it does not belong in the "C++ Gurus" subforum (which is for questions about C++ concepts and techniques).

Moved to the "General and Desktop" subforum.
