一直比較推崇QT這個介面庫，所以打算把osg嵌入到QT裡面做一個QWidget的子控制元件。在查閱了官方的osgViewerQT後，決定寫一個子類，同時繼承osgViewer::Viewer和QGLWidget，用一個Widget來顯示osg的單Viewer的場景。class OsgQtWidget : public QGLWidget, public osgViewer::Viewer{Q_OBJECTpublic:OsgQtWidget(QWidget *parent = 0, const QGLWidget * shareWidget = 0, Qt::WFlags flags = 0);OsgQtWidget(osgViewer::ViewerBase::ThreadingModel threadingModel = osgViewer::Viewer::SingleThreaded);~OsgQtWidget();void setScene();osg::Camera* createCamera( int x, int y, int w, int h, const std::string& name="", bool windowDecoration=false );virtual void paintGL();private:protected:QTimer timer;};
