QString mystery

[JPNaude]

Hi

I've used QString many many times before but the following does not make any sense to me. I have this code:

QString version;
QString seperator = QString(".");
int minor = 0;
int major = 0;
if (minor <= 9)
    version = QString("%1%200%3").arg(major).arg(seperator).arg(minor);
else if (minor <= 99)
    version = QString("%1%20%3").arg(major).arg(seperator).arg(minor);
else
    version = QString("%1%2%3").arg(major).arg(seperator).arg(minor);
 
qDebug() << seperator;
qDebug() << version;

QString version;
QString seperator = QString(".");
int minor = 0;
int major = 0;
if (minor <= 9)
    version = QString("%1%200%3").arg(major).arg(seperator).arg(minor);
else if (minor <= 99)
    version = QString("%1%20%3").arg(major).arg(seperator).arg(minor);
else
    version = QString("%1%2%3").arg(major).arg(seperator).arg(minor);

qDebug() << seperator;
qDebug() << version;

To copy to clipboard, switch view to plain text mode 

Amazingly the qDebug() outputs gives:

"." 
"000."

"." 
"000."

To copy to clipboard, switch view to plain text mode 

While the result should clearly be "0.000"

If anyone can give an explanation why version is wrong, I would really appreciate it.
Thanks,
Jac

Solved it:

QString version = QString::number(major) + QString(".%1").arg(minor,3,10,QChar('0'));

QString version = QString::number(major) + QString(".%1").arg(minor,3,10,QChar('0'));

Try this:

QString version;
QString seperator = QString(".");
int minor = 0;
int major = 0;
if (minor <= 9)
    version = QString("%1%200%3").arg(QString::number(major)).arg(seperator).arg(QString::number(minor));
...//etc
qDebug() << seperator;
qDebug() << version;

QString version;
QString seperator = QString(".");
int minor = 0;
int major = 0;
if (minor <= 9)
    version = QString("%1%200%3").arg(QString::number(major)).arg(seperator).arg(QString::number(minor));
...//etc
qDebug() << seperator;
qDebug() << version;
