Hello sumit!
Thank you for all your help.
I have attached the code in the first message, even so I write this below.
Regards, Juan
Code:
/// MAIN
int main(int argc, char **argv){
QApplication app(argc, argv);
OsgViewerQt *OSGQT = new OsgViewerQt;
return 0;
}
/// CLASS OSGViewerQT
class OsgViewerQt : public QGLWidget , public osgViewer::Viewer {
Q_OBJECT
private:
osg::ref_ptr<osg::Group> root;
public:
OsgViewerQt( QWidget *parent = 0, const QGLWidget *shareWidget
= 0, WindowFlags f = 0 ):
QGLWidget ( parent, shareWidget, f ),
osgViewer::Viewer(){
_gw = new osgViewer::GraphicsWindowEmbedded ( 0, 0,
width(), height() );
setFocusPolicy (Qt::ClickFocus);
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 );
osg::ref_ptr<osg::Node> loadedModel =
osgDB::readNodeFile ( "cow.osg" );
setSceneData( loadedModel );
connect ( &timer, SIGNAL( timeout() ), this, SLOT (
updateGL() ));
timer.start(10);
show();
}
~OsgViewerQt();
virtual void paintGL() { frame(); }
osgViewer::GraphicsWindow *getGraphicsWindow () { return
_gw.get(); }
const osgViewer::GraphicsWindow *getGraphicsWindow () const {
return _gw.get(); }
void init ();

virtual void resizeGL( int width, int height ){
_gw->getEventQueue()->windowResize(0, 0, width, height

_gw->resized(0,0,width,height);
}

_gw->getEventQueue()->keyPress(
(osgGA::GUIEventAdapter::KeySymbol) *(event->text().toAscii().data() ) );
}
virtual void keyReleaseEvent( QKeyEvent* event ){
