Used it a few years ago but have a look at QStyle::pixelMetric and
PM_ScrollBarExtent.
Try someting like this:

int CustomStyle::pixelMetric(
PixelMetric<http://doc.trolltech.com/3.3/qstyle.html#PixelMetric-enum>
metric,
const QWidget <http://doc.trolltech.com/3.3/qwidget.html> * widget ) const
{
    if( metric==QStyle::PM_ScrollBarExtent )
        return 50;
    else
        return QStyle::pixelMetric(metric, widget);
}


Cheers,
Tim
