[osg-users] osgQt aspect ratio issue when inside QMainWindow

[OpenSceneGraph Users]

Hi,
I am trying to put an osgQOpenGLWidget inside a QMainWindow. I managed to 
made it quite easily but the resulting image is stretched and I cannot 
change its aspect ratio to made it right (the cow.osg is really stretched).
Can you help me, please? I have been struggling with this few lines of code 
for 5 days now.

I can provide source code as follows...

Thank you so much

#include "mainwindow.h"

MainWindow::MainWindow(QWidget *parent)
        : QMainWindow(parent)
{
    QSurfaceFormat format = QSurfaceFormat::defaultFormat();
    format.setVersion(2, 0);
    format.setProfile(QSurfaceFormat::CompatibilityProfile);
    format.setRenderableType(QSurfaceFormat::OpenGL);
    format.setOption(QSurfaceFormat::DebugContext);
    format.setDepthBufferSize(24);
    format.setSamples(8);
    format.setStencilBufferSize(8);
    format.setSwapBehavior(QSurfaceFormat::DoubleBuffer);
    QSurfaceFormat::setDefaultFormat(format);

    osgWidget = new osgQOpenGLWidget(this);
    QObject::connect(osgWidget, &osgQOpenGLWidget::initialized, this, &MainWindow::setupOsgView);

    setCentralWidget(osgWidget);
    osgWidget->show();
}

void MainWindow::setupOsgView() {

    osgWidget->getOsgViewer()->setCameraManipulator(new osgGA::TerrainManipulator());
    osgWidget->getOsgViewer()->addEventHandler(new osgGA::StateSetManipulator(osgWidget->getOsgViewer()->getCamera()->getOrCreateStateSet()));
    osgWidget->getOsgViewer()->addEventHandler(new osgViewer::ThreadingHandler);
    osgWidget->getOsgViewer()->addEventHandler(new osgViewer::WindowSizeHandler);
    osgWidget->getOsgViewer()->addEventHandler(new osgViewer::StatsHandler);
    osgWidget->getOsgViewer()->addEventHandler(new osgViewer::RecordCameraPathHandler);
    osgWidget->getOsgViewer()->addEventHandler(new osgViewer::LODScaleHandler);
    osgWidget->getOsgViewer()->addEventHandler(new osgViewer::ScreenCaptureHandler);

    osg::ref_ptr<osg::Node> loadedModel = osgDB::readRefNodeFile("cow.osg");
    if(!loadedModel) {
        std::cout << "No data loaded" << std::endl;
    }

    osgUtil::Optimizer optimizer;
    optimizer.optimize(loadedModel);

    osgWidget->getOsgViewer()->setSceneData(loadedModel);
}

MainWindow::~MainWindow()
{

}
