[solved] Condition in QString .arg() ?

[deleted28]

Is it possible to place a condition inside .arg() of a QString.

e.g. something like this :

@ QString hello = QString("hello %1, how are you")
.arg( ?cond? );

    ?cond? : 
           
    if (TRUE) {
        return "Joe"
    } else {
        return "Harry"
    }
                   
    qDebug() << hello;@

@ QString hello = QString("hello %1, how are you") .arg((TRUE)?QStringLiteral("Joe"):QStringLiteral("Harry"));@

Like that?

error: 'QStringLiteral' was not declared in this scope

seems not available in Qt 4.8.1 (?)
