[Qt-interest] QT string templating

[Constantin Makshin]

Although not very important in this particular case, in general I think it's better to replace numbers in the first place to make sure that "%..." parts that may be present in replacement strings will stay intact.

Example:

#include <QDebug>
#include <QString>
int main (int, char**)
{
    QLatin1String str("[%1]");
    int num = 123;
    qDebug() << QString("str, num: str=%1, num=%2").arg(str).arg(num);
    qDebug() << QString("num, str: str=%2, num=%1").arg(num).arg(str);
    return 0;
}

Outputs:
"str, num: str=[123], num=%2" 
"num, str: str=[%1], num=123"
