can we change QPixmap image of Qgraphicsscene dynamically?

[sh123]

1 another query.

I have added QGraphicsview in Vertical Layout to view an image.

Now I want to rotate this image as well as move it vertically up and down.

I am able to rotate it using code

matrix.rotate(i);

ui.BGgraphicsView->setMatrix(matrix);

ui.BGgraphicsView->setMatrix(matrix);

To copy to clipboard, switch view to plain text mode 

but not able to move it up and down

I use below code for translating

matrix.translate(50,50);
ui.BGgraphicsView->setMatrix(matrix);

matrix.translate(50,50);
ui.BGgraphicsView->setMatrix(matrix);

To copy to clipboard, switch view to plain text mode 

Please help

SetPixmap does removes the current image from pixmap but not displaying the new pixmap image instead white empty Graphicsview is seen .
