int main(int argc, char** argv) {
osg::ref_ptr<osgWidget::WindowManager> wm = new osgWidget::WindowManager(0, 0, 800, 600, osgWidget::WINDOW_MANAGER_AUTO_CLEAR);
osg::ref_ptr<osgDB::Options> options = new osgDB::Options;
osgDB::Registry::instance()->setOptions(options);
osgDB::Registry::instance()->loadPlugin("osgdb_browser");
osg::ref_ptr<osgWidget::Box> box = new osgWidget::Box("Box", osgWidget::Box::VERTICAL);
osg::ref_ptr<osgWidget::Browser> browser = osgWidget::BrowserManager::createBrowser(800, 600, "http://www.baidu.com");
box->addWidget(browser);
osg::ref_ptr<osgViewer::Viewer> viewer = new osgViewer::Viewer;
viewer->setUpViewInWindow(50, 50, 800, 600);
viewer->setSceneData(wm);
viewer->addEventHandler(new osgWidget::MouseHandler(wm.get()));
viewer->addEventHandler(new osgWidget::KeyboardHandler(wm.get()));
viewer->addEventHandler(new osgWidget::ResizeHandler(wm.get(), viewer->getCamera()));
