QFontMetrics, i can't understand

[marcel]

fmetrics::fmetrics(QWidget *parent, Qt::WFlags flags)
    : QDialog(parent, flags)
{
    ui.setupUi(this);
 
    QFontMetrics metrics(ui.label->font());
    QFontMetrics metrics2(ui.label_2->font());
 
    qDebug( QString("%1").arg(metrics.width(ui.label->text())).toAscii().constData() );
    qDebug( QString("%1").arg(metrics2.width(ui.label_2->text())).toAscii().constData() );
}

fmetrics::fmetrics(QWidget *parent, Qt::WFlags flags)
    : QDialog(parent, flags)
{
    ui.setupUi(this);

    QFontMetrics metrics(ui.label->font());
    QFontMetrics metrics2(ui.label_2->font());

    qDebug( QString("%1").arg(metrics.width(ui.label->text())).toAscii().constData() );
    qDebug( QString("%1").arg(metrics2.width(ui.label_2->text())).toAscii().constData() );
}

To copy to clipboard, switch view to plain text mode 

label and label_2 are two QLabels with the same font set. One has normal font and the other has a bold font.

I always get a smaller width for the label with normal font. I tried with several fonts.

What font did you use?
