What font for adding numbers in GraphicsScene

[droelf]

I need to add int numbers in a field, but they are all blurry.
I used this:

QPen blackPen(Qt::black);
QPen redPen(Qt::red);
QBrush redBrush(Qt::red);
blackPen.setWidth(2);
if(cost!=0){
    myFont.setBold(false);
    myFont.setPixelSize(14);
    myFont.setFamily("Times");
    mainW->scene->addLine(f->getPos().x(),f->getPos().y(),t->getPos().x(),t->getPos().y(),blackPen);
    QString s = QString::number(cost);
    qreal x;
    qreal y;
    x = (0.5*(f->getPos().x() + t->getPos().x()))-5;
    y = (0.5*(f->getPos().y() + t->getPos().y()))-8;
    path.addText(x,y,myFont,s);
    mainW->scene->addPath(path,redPen,redBrush);

Any ideas? :/
