[osg-users] Use OSG with QT
Hi, I want to integrate OSG(2.8.2) with QT(4.7.1). I tried the example http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/examples/osgQtBrowser/osgQtBrowser.cpp but when I compile it i have an error: the inclusion file osgQt/QGraphicsViewAdapter is not found.

[osg-users] Add a new child
Hi, i created a menu where i can select a model. When i select a button a fuction loads the nodes with the following code: Code: listaComponenti.push_back(osgDB::readNodeFile(aorta.ive)); listaComponenti.push_back(osgDB::readNodeFile(cuore.ive)); unsigned int ii; for(ii=0; ii listaComponenti.size(); ii++) switchA-addChild((listaComponenti[ii]), true); root-addChild(switchA.get()); In the main fuction i have this code: Code: if(!wm) return 1; osg::Group* group = new osg::Group(); osg::Camera* camera = wm-createParentOrthoCamera(); group-addChild(camera); if(root) group-addChild(root); viewer.addEventHandler(new osgWidget::MouseHandler(wm)); viewer.addEventHandler(new osgWidget::KeyboardHandler(wm)); viewer.addEventHandler(new osgWidget::ResizeHandler(wm, camera)); viewer.addEventHandler(new osgWidget::CameraSwitchHandler(wm, camera)); viewer.addEventHandler(new osgViewer::StatsHandler()); viewer.addEventHandler(new osgViewer::WindowSizeHandler()); viewer.addEventHandler(new osgGA::StateSetManipulator(viewer.getCamera()-getOrCreateStateSet())); wm-resizeAllWindows(); viewer.setSceneData(group); /*/ //viewer.getCamera()-setClearColor(osg::Vec4(0.,0.,0.,1)); return viewer.run(); The problem is that the software doesn't show the node in execution but if i load the model before, without the button callback, the software shows the node.
