示例2 (使用setDevToolsPage函数)

- 代码:

int main(int argc, char *argv[])
{QApplication a(argc, argv);//MainWindow w;//w.show();QWebEngineView *view = new QWebEngineView();QWebEngineView *view1 = new QWebEngineView();view->setUrl(QUrl("http://baidu.com"));view->page()->setDevToolsPage(view1->page());view->setWindowTitle("BaiDu");view1->setWindowTitle("DevTool");view->show();//显示页面view1->show();//显示view页面的JS脚本(也就是说:view1是view的开发者工具)return a.exec();
