Rotating pixmap

Hello, I want to rotate the pixmap of the QGraphicsPixmap item and show the item rotated. Rotating the item cause other sort of problems.

So far, I never had problems when rotating the pixmaps, but I don't know why now the rotation is not taking from the center and rotates the pixmap, it's like its rotated without the translation and I don't know why.

Qt Code:

Switch view

//m_pxOriginal is a copy of the original pixmap. Not rotated.
qreal rRadius = m_pxOriginal.width() / 2;
 
		//Rotate the previous rotation - 10 degrees
		m_iAngle -= 10;
 
QPixmap rotatedPix = m_pxOriginal .transformed(QTransform().translate(-rRadius, -rRadius).rotate(m_iAngle).translate(rRadius, rRadius));
 
		m_pxItem->setPixmap(rotatedPix);

//m_pxOriginal is a copy of the original pixmap. Not rotated.
qreal rRadius = m_pxOriginal.width() / 2;

		//Rotate the previous rotation - 10 degrees
		m_iAngle -= 10;

QPixmap rotatedPix = m_pxOriginal .transformed(QTransform().translate(-rRadius, -rRadius).rotate(m_iAngle).translate(rRadius, rRadius));

		m_pxItem->setPixmap(rotatedPix);

To copy to clipboard, switch view to plain text mode

Anything strange? :S thanks!
