QT QWebEngineView加载网页 resize 与 resizeEvent的区别

QWebEngineView加载网页
1.pro文件中写入

QT       += core gui webenginewidgets

2.头文件加入

#include <QtWebEngineWidgets>

namespace Ui {class MainWindow;}class MainWindow : public QMainWindow{    Q_OBJECTpublic:    explicit MainWindow(QWidget *parent = 0);    ~MainWindow();protected:    void resizeEvent(QResizeEvent *);private slots:    void on_pushButton_clicked();private:    Ui::MainWindow *ui;    QWebEngineView *view;};

3.主文件：

MainWindow::MainWindow(QWidget *parent) :    QMainWindow(parent),    ui(new Ui::MainWindow){    ui->setupUi(this);    view = new QWebEngineView(this);    //view->resize(this->size());    view->load(QUrl("http://www.baidu.com/"));    view->hide();}void MainWindow::resizeEvent(QResizeEvent *event){    view->resize(this->width(),this->height()-50);}void MainWindow::on_pushButton_clicked(){    //    view = new QWebEngineView(this);    //    view->resize(ui->frame->size());    //    view->load(QUrl("http://www.baidu.com/"));    view->show();}

直接启用浏览器加载网页方法：

QDesktopServices::openUrl(QUrl("http://www.baidu.com"));

不写入resizeEvent时，调用

view->resize(this->width(),this->height()-50);

运行结果不可动态拉伸

写入resizeEvent 运行结果可以动态拉伸。
