Needle for QwtDial

I have created a dial using QwtDial but it is not having any needle. Tried to create an object of QwtDialNeedle class as QwtDialNeedle *nd; d->setNeedle(nd); No error and it is not showing any needle.
Can anyone help me to draw a needle.

Thanks in Advance

Hi,
did you look at the 'dials' example?

Code:

---

QwtDialSimpleNeedle *needle = new QwtDialSimpleNeedle(
        QwtDialSimpleNeedle::Arrow, true, Qt::red,
        QColor( Qt::gray ).light( 130 ) );
    setNeedle( needle );
