Hi, I'm using OSG 3.2.2 with Qt 5.4.1. Compiler is VS2013.
To integrate into QtWidget I used a tutorial code, shown beneath. The program crashes very often when I start it. I would say 8 of 10 tries. When the program has started correctly everything is working fine. I had the same problem on another machine and switched the compiled VS 2013 OSG sources and 3rdParty Tools to a version compiled with VS2012 and it worked. The error did not occurred any more. On another machine this is not working. Error occurs with VS 2013 and VS2012 compiler. I donĀ“t know where the error could be or where to start. Any suggestions are welcome. The program crashes and it says APPCRASH, error in ot20-OpenThreadsd.dll when I debug it with VS2013 it looks like he crashes in Viewer.frame, or OpenThreads::setProcessorAffinity So where could be the problem? Thank you for your help. Code: ViewerWidgetAS1::ViewerWidgetAS1( osgQt::GraphicsWindowQt* gw, osg::Node* scene, Ui::scenario1 *sceneUi, mySock *mysock1) : QWidget() { const osg::GraphicsContext::Traits* traits = gw->getTraits(); osg::Camera* camera = _viewer.getCamera(); camera->setGraphicsContext( gw ); camera->setClearColor( osg::Vec4(0.2, 0.2, 0.6, 1.0) ); camera->setViewport( new osg::Viewport(0, 0, traits->width, traits->height) ); camera->setProjectionMatrixAsPerspective( 30.0f, static_cast<double>(traits->width)/static_cast<double>(traits->height), 1.0f, 5000.0f ); _viewer.setSceneData( scene ); _viewer.addEventHandler( new osgViewer::StatsHandler ); osg::Vec3d eye( 1249.0, -390.0, 2200.0 ); osg::Vec3d center( 1250.0, -390.0, 285.0 ); osg::Vec3d up( 0.0, 1.0, 0.0 ); _viewer.getCamera()->setViewMatrixAsLookAt( eye, center, up ); _viewer.setThreadingModel( osgViewer::Viewer::SingleThreaded ); picker = new PickHandler(...); _viewer.addEventHandler(picker); QVBoxLayout* layout = new QVBoxLayout; layout->addWidget( gw->getGLWidget() ); setLayout( layout ); connect( &_timer, SIGNAL(timeout()), this, SLOT(update()) ); _timer.start( 10 ); // full screen antialiasing (if supported) osg::DisplaySettings::instance()->setNumMultiSamples( 16 ); //Add Group Node to root Node m_scene->addChild(groupNodeGeodes); // m_scene->addChild(groupNodeLines); } ...
