QQuickWidget on QGraphicsScene

[Luckless]

I have a certain drawing in a qml where I am loading a few images. I am loading this qml on a QQuickWidget pointer using:

m_quickWidget = new QuickWidget(QUrl("......"));

Then I have done the following:

QWidget *baseWid = new QWidget();
baseWid->setGeometry(.......);
layer->QMLItem()->setParent(baseWid);
//layer->QMLItem() returns m_quickWidget
scene()->addWidget(baseWid);
//Add QWidget to QGraphicsScene (returned by scene())

Now, I am able to see all my drawings that were done in qml, but the images that I loaded are getting blurred(stretched).If I directly show m_quickWidget instead of adding to QGraphicsScene, image is clear.

What should i do to get the drawing right, using QGraphicsScene?
