1) QwtKnob::setFont()
2) You need QwtScaleIf::d_scale. Here you need to change d_medLen,
    d_majLen, d_minLen. For both there is no API.

Also QwtScaleIf::d_scale. You need to overload QwtScaleDraw::label().
Make QwtScaleIf::d_scale a pointer and invent a setScaleDraw (like in 
QwtScale). Next derive your own QwtScale class write your own label().
