Enabling vsync

[black_gay]

Id like to know if the settings below are enough to enable vsync for qt application:

evel1::Level1()
{
    this->setSceneRect(sceneRect);
    m_view = new QGraphicsView();
 
    QOpenGLWidget *gl = new QOpenGLWidget();
    QSurfaceFormat format;
    format.setProfile(QSurfaceFormat::CompatibilityProfile);
    format.setOptions(QSurfaceFormat::DeprecatedFunctions);
    format.setDepthBufferSize(24);
    format.setStencilBufferSize(8);
    format.setVersion(3, 2);
    format.setSwapBehavior(QSurfaceFormat::DoubleBuffer);
    format.setSwapInterval(1);
    gl->setFormat(format);
     QSurfaceFormat::setDefaultFormat(format);
    m_view->setViewport(gl);
 
 
    m_view->setScene(this);
    m_view->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    m_view->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    m_view->setWindowTitle(QT_TRANSLATE_NOOP(QGraphicsView, "game"));
    m_view->resize(800, 600);
    m_view->setRenderHints(QPainter::Antialiasing | QPainter::SmoothPixmapTransform);
    m_view->setViewportUpdateMode(QGraphicsView::NoViewportUpdate );
    m_view->setCacheMode(QGraphicsView::CacheBackground);
    m_view->updateGeometry();
    painter = new QPainter();
    m_view->setSceneRect(0,0,10000000,10000000);
    m_view->setBackgroundBrush(Qt::black);
    m_view->show();
    m_view->showFullScreen();
 
 
}
