QWMatrix::mapRect

[Pharell]

Hello all,

I am fighting with a problem regarding mapping a rectangle which is not of

QRect type. I want to rotate the rectangle 90 degree counterclockwise and

I just did it as follow but the result is not what I want.Instead the rectangle

gets larger in size. Can someone give me suggestions how to solve this problem?

QWMatrix matrixWorld;
	 QRect newRect;
	 double rotateDegree = 90.0;
 
	 newRect.setRect(myRect.Left(), myRect.Top(), myRect.Width(), myRect.Height()); 
	 matrixWorld.rotate(rotateDegree);
	 newRect =  matrixWorld.mapRect(newRect);
	 myRect.Rect(newRect.left(), newRect.top(), newRect.width(), newRect.height());

QWMatrix matrixWorld;
	 QRect newRect;
	 double rotateDegree = 90.0;

	 newRect.setRect(myRect.Left(), myRect.Top(), myRect.Width(), myRect.Height()); 
	 matrixWorld.rotate(rotateDegree);
	 newRect =  matrixWorld.mapRect(newRect);
	 myRect.Rect(newRect.left(), newRect.top(), newRect.width(), newRect.height());
