GALLERY: Qwidget Rotate

Loading...

I am trying to rotate a QWidget. I am already able to rotate a QPixmap using QPainter. I know you can't rotate a QLabel but how can I rotate a Qwidget or some container.

void RotateImage::paintEvent(QPaintEvent *event)
{
QPainter paint(this);
QPixmap map(200,200);
if (!map.load("myphoto.JPG")) {
qDebug() << " Load fail "<<endl;
return;
}
paint.translate(200,200);
paint.rotate(90);
paint.drawPixmap(0,0,200,200,map);
