Rotating a pixmap inside a widget

[Eneswar]

Hello, I need help with rotating a pixmap inside a widget. What I have is a Circle and a Pointer, they are both 2 seperated images. (Think about a Tachometer) I have already the pointer in the middle of the circle as I want. What I am failing with is to rotate the pointer as I want.

I can rotate it but its not rotating from the point where I need it to rotate. Right now it is rotating from somewhere I dont know where, I need the pointer to stay where it is and rotate from there.

Open Qt Assistant and look for "Analog Clock Example" in the Index

Alright will do, thank you.





Im still having trouble figuring this out.

My code:

boolPainter.drawPixmap(0, 0, QPixmap(":/Image/CircleDark"));
        boolPainter.drawPixmap(0,0, QPixmap(":/Image/Pointer"));

boolPainter.drawPixmap(0, 0, QPixmap(":/Image/CircleDark"));
        boolPainter.drawPixmap(0,0, QPixmap(":/Image/Pointer"));

To copy to clipboard, switch view to plain text mode 

Its the Pointer I need rotate, could I get some kind of example or something?

I have got it sorted with:

item->setTransform(QTransform().translate(x, y).rotate(45).translate(-x, -y));

item->setTransform(QTransform().translate(x, y).rotate(45).translate(-x, -y));
