Qt::Key_Return

[estel]

I have found it in one of examples.

if (splash->isVisible() || event->key() == Qt::Key_Return || flipped) {
        QGraphicsView::keyPressEvent(event);
        return;
    }

if (splash->isVisible() || event->key() == Qt::Key_Return || flipped) {
        QGraphicsView::keyPressEvent(event);
        return;
    }

Could you tell me what is Key_Return?
