QwtPolar - Title for Radius Axis

[Uwe]

I would derive from QwtScaleDraw and overload one of its virtual methods, adding the QPainter::drawText() call you need. F.e:

class YourRadiusScaleDraw: public QwtScaleDraw
{
   ...
protected:
    virtiual void drawBackbone( QPainter *painter ) const
    {
        QwtScaleDraw::drawBackbone( painter );
 
        // now calculate the position/alignment/rotation for your text and
        // do the painter->:drawText() call
        ...
    }
};

class YourRadiusScaleDraw: public QwtScaleDraw
{
   ...
protected:
    virtiual void drawBackbone( QPainter *painter ) const
    {
        QwtScaleDraw::drawBackbone( painter );

        // now calculate the position/alignment/rotation for your text and
        // do the painter->:drawText() call
        ...
    }
};
