I have a dial control over an image

scene->addPixmap(*pixmap);
this->ui->graphicsView->setScene(scene);

and I want to see the underlying image also in the control area. I tried for example

this->ui->dial->setStyleSheet("QWidget{background-color: rgba(0,250, 0,40%);}");

but the control is opaque, I cannot see the image beneath, whatever % I set for the alpha channel. Which are the right instructions?

What's the base class of your dial? – Phlucious Nov 19 '12 at 21:22
@Phlucious it' a common dial from the QT controls palette, so I think it's the QDial class. – P5music Nov 20 '12 at 08:57
