Re: axis marking format

[Uwe R. <Uwe...@ep...>]

I've commited the following changes to CVS:

class QwtScaleDraw
{
public:
    virtual void draw(QPainter *p) const;

protected:
    virtual QString label(double value) const;
    virtual int maxLabelWidth(const QFontMetrics &) const;
};

class QwtScale
{
public:
    void setScaleDraw(QwtScaleDraw *);
    const QwtScaleDraw *scaleDraw() const;
};

class QwtPlot
{
public:
    void setAxisScaleDraw(int axis, QwtScaleDraw *);
    const QwtScaleDraw *axisScaleDraw(int axis) const;
};

A completely satisfying solution requires much more redesign than I like to 
do in Qwt 0.4.x, but this small solution makes it possible to use not 
printf-like scale labels. Please note that an fieldwidth != 0 will have an 
effect on the layout via maxLabelWidth() even if an overloaded label() won't 
use it anymore.

HTH,
Uwe
