Hi everyone
In QTOSG example,When i modify the thread model to
osgViewer::Viewer::DrawThreadPerContext); I get a runtime error!
class ViewerQT : public osgViewer::Viewer, public AdapterWidget
{
public:
ViewerQT(QWidget * parent = 0, const char * name = 0, const QGLWidget *
shareWidget = 0, WindowFlags f = 0):
AdapterWidget( parent, name, shareWidget, f )
{
getCamera()->setViewport(new osg::Viewport(0,0,width(),height()));
getCamera()->setProjectionMatrixAsPerspective(30.0f,
static_cast<double>(width())/static_cast<double>(height()), 1.0f, 10000.0f);
getCamera()->setGraphicsContext(getGraphicsWindow());
setThreadingModel(osgViewer::Viewer::SingleThreaded);
//setThreadingModel(osgViewer::Viewer::DrawThreadPerContext); //here i
modify
addEventHandler(new osgGA::StateSetManipulator );
connect(&_timer, SIGNAL(timeout()), this, SLOT(updateGL()));
_timer.start(10);
}
virtual void paintGL()
{
frame();
}
protected:
QTimer _timer;
};
Thanks YangXiao.
