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(); }
