Draw Text inside a dial

Hello.

AttitudeIndicator class within the example "dials" show how to customize a QwtDialNeedle.

Thus one can get some free space within the dial to print the present angle value within the dial
if the space outside the dial is scarce.

I thought that something like:

Code:

---

void AttitudeIndicator::paintEvent( QPaintEvent *event )
{
    QPainter painter(this);
    painter.save();
    painter.drawText(innerRect().center(),QString::number(value()));
    painter.restore();
}

---

would help, but this paintEvent function only updates the text without repainting the dial itself.

Is there any elegant workaround for this?

Thanks.

The SpeedoMeter class of the dials example does something similar.

Yes, I looked at the SpeedoMeter class.
Adding

Code:

---

d_speedo->setLabel(QString::number(d_speedo->value()) + "km/h");

---

to the end of void CockpitGrid::changeSpeed() almost solves it,
it is only that the km/h "Label" gets updated only if the main (parent) widget is resized.

Just for the record:
QWT Dial, show unit
