Hi, I got a file maybe helpful to you. There's a .h file that defines an class
of an osgView. In your project, there should be a ui, and add the code bottom.
#include "Viewer.h"
...
ViewerWidget *osgview;
osgview = new ViewerWidget;
ui.horizontalLayout->addWidget(osgview);
The .h file:
#ifndef _SATLITEVIEWER_H_
#define _SATLITEVIEWER_H_
#include <osg/Node>
#include <QtCore/QTimer>
#include <QtGui/QApplication>
#include <QtGui/QGridLayout>
#include <osgViewer/CompositeViewer>
#include <osgViewer/ViewerEventHandlers>
#include <osgGA/TrackballManipulator>
#include <osgDB/ReadFile>
#include <osgQt/GraphicsWindowQt>
#include <iostream>
class ViewerWidget : public QWidget, public osgViewer::CompositeViewer

threadingModel=osgViewer::CompositeViewer::SingleThreaded)
{
setThreadingModel(threadingModel);
osg::Group *root = new osg::Group;
osg::Node *satNode = osgDB::readNodeFile("cow.osg");
root->addChild(satNode);
QWidget* widget1 = addViewWidget( createCamera(0,0,100,100),
root );
/*
