You would use QGraphicsView::setRenderHint(QPainter::RenderHint) on your view with QPainter::Antialiasing flag as an argument.

For example:

myView->setRenderHint(QPainter::Antialiasing);

If you are not satisfied with the results, then you can try this: setViewport(QWidget*)to QGLWidget and turn on the QPainter::HighQualityAntialiasing render hint.

myView->setViewport(new QGLWidget);
myView->setRenderHint(QPainter::HighQualityAntialiasing);
