Definitely not like this

Try this instead:

QGraphicsView *gv = new QGraphicsView;
gv->setScene(new QGraphicsScene);
gv->scene()->addPixmap(QPixmap("somepixmap.png"));
gv->show();

QGraphicsView *gv = new QGraphicsView;
gv->setScene(new QGraphicsScene);
gv->scene()->addPixmap(QPixmap("somepixmap.png"));
gv->show();

To copy to clipboard, switch view to plain text mode 

And next time please try to find some code snippet or documentation paragraph that is at least somewhat similar to your problem.
