Adding style inside QwtDial

[claudiacrb]

Hi, I'm working in a circular diagram using qwt dials. The diagram is much like a clock (three needles pointing different angles). Is it possible to draw one or two internal circles inside the scale? I need them for reference, since the length of the needle indicates an important value in my GUI.

I used the qwtClockDial code and adapted it to my needs, but I haven't found the way to do what I asked above.

I don't have much experience working with qwt so if anyone could give me a hint, it would be appreciated.

Thanks!

Overload one of the following:

• virtual void QwtDial::drawContents (QPainter *) const
• virtual void QwtDial::drawScaleContents (QPainter *painter, const QPointF &center, double radius) const

Check the dials example,

Surprisingly the dials example can be found in the directory: examples/dials.
