Ah oops, totally forgot that.
I managed to compile and link with QT now, but when I run my app, I get the
following error:
"QPaintDevice: Must construct a QApplication before a QPaintDevice".
Do you have an idea what might be wrong? I understand the error, but I am
creating my QApplication-object before anything else!
My main looks like this:
// initialize OSG
OSG::osgInit(argc, argv);
// initialize QT
QApplication::setColorSpec(QApplication::CustomColor);
QApplication a(argc, argv);
// create windows
QGLFormat::setDefaultFormat(QGLFormat(QGL::DirectRendering |
QGL::DoubleBuffer | QGL::DepthBuffer | QGL::Rgba));
// initialize scene
Scene* scene = new Scene("data/world.xml");
// initialize window
SceneWindow* sceneWindow = new SceneWindow();
OSG::QTWindowPtr win = OSG::QTWindow::create();
win->setGlWidget(sceneWindow);
sceneWindow->m_simpleSceneManager.setWindow(win);
sceneWindow->m_simpleSceneManager.setRoot(scene->getRoot());
sceneWindow->m_simpleSceneManager.showAll();
// process events
a.processEvents();
// show scene
sceneWindow->show();
a.setMainWidget(sceneWindow);
return (a.exec());
Thanks a lot Andreas,
Peter
