Damn, I just had found what I think is a simpler fix, but had to leave taking
pics of a friend's rock band.
Anyway, my fix is to use the following as the RulerScale for the tempo and
chord ruler :
class ZoomableMatrixHLayoutRulerScale : public RulerScale, public HZoomable {
public:
ZoomableMatrixHLayoutRulerScale(MatrixHLayout& layout) :
RulerScale(layout.getComposition()), m_referenceHLayout(layout) {};
virtual double getBarPosition(int n) const { return
m_referenceHLayout.getBarPosition(n) * getHScaleFactor(); }
virtual double getXForTime(timeT time) const { return
m_referenceHLayout.getXForTime(time) * getHScaleFactor(); }
virtual timeT getTimeForX(double x) const { return
m_referenceHLayout.getTimeForX(x / getHScaleFactor()); }
virtual double getBarWidth(int n) const { return
m_referenceHLayout.getBarWidth(n) * getHScaleFactor(); }
virtual int getLastVisibleBar() const { return
m_referenceHLayout.getLastVisibleBar(); }
protected:
MatrixHLayout& m_referenceHLayout;
};
Seems to work here. What do you think ?
