Display two needles in a single QwtDial

Hi!

This question has been brought up earlier on, but it has not been properly answered. How do I display two needles in a single QwtDial? Can anybody help me with this?
The only properties I am interested in is to be able to change the color and value of the two needles.


I made the QwtDial in Qt Designer, and this is how I make the single needle in QwtDial:

Code:

---

QwtDialSimpleNeedle *needle = new QwtDialSimpleNeedle(QwtDialSimpleNeedle::Arrow, true, Qt::red, QColor(Qt::gray).light(130));
		 MainEngineRight->setRange(-1.0,1.,0.01);
		 MainEngineRight->setNeedle(needle);

Best regards

Why are you posting it again and again? If somebody knows, then they had already posted the answer.

QwtAnalogClock is a QwtDial with 3 needles - check its implementation.

sonulohani: I did not create the original post, and that post is several years old. I could of course have brought the old topic back alive.

Uwe: Thanks for the tip. I will check the implementation.
