can I get another QGraphicsView's scene?

[sincnarf]

I want to print a QGraphicsScene's contents. How do I do this? The following code is wrong

void MainWindow::print()
 {
QPrinter printer;
if (QPrintDialog(&printer).exec() == QDialog::Accepted) {
     QPainter painter(&printer);
     painter.setRenderHint(QPainter::Antialiasing);
     //QGraphicsScene scene = anotherQGraphicsView->scene();
     //What lines of code should I use to get another QGraphicsView's scene
     //No method like getScene() exists
     scene->render(&painter);
}
 }

void MainWindow::print()
 {
QPrinter printer;
if (QPrintDialog(&printer).exec() == QDialog::Accepted) {
     QPainter painter(&printer);
     painter.setRenderHint(QPainter::Antialiasing);
     //QGraphicsScene scene = anotherQGraphicsView->scene();
     //What lines of code should I use to get another QGraphicsView's scene
     //No method like getScene() exists
     scene->render(&painter);
}
 }
