c++ - QWebEngineView加载url后直接点击链接没有反应要怎么解决？

Question

我用QWebEngineView加载一个url后，直接点击链接没有任何反应，要在链接上右键点击，然后通过菜单的Follow Link才能打开。初学Qt能力有限，找了QWebEngineView和QWebEnginePage的文档愣是没看到有相关的方法，求大家帮忙看看。

网上资料太少了,全是QWebView的，可是我用的是Qt5.6，已经没有这个模块了。

Answer 1

In QWebEngineView there are the following methods:

QWebEngineView *QWebEngineView::createWindow(QWebEnginePage::WebWindowType type)

This method will be triggered when the left mouse button is clicked. You can overload it and use your own implementation.

Answer 2

This bug seems to have nothing to do with the createWindow function.
In QWebEngineView, when a user clicks on a link on a web page, a signal will be triggered:
urlChanged(QUrl)
But QWebEngineView will not automatically load new links.

So you need to create a new slot function for urlChanged(QUrl) yourself and manually load the new link in the parameters yourself.
For example:

connect(m_pView, SIGNAL(urlChanged(QUrl)), 
        this, SLOT(onUrlChanged(QUrl)));
        

//Webpage link address
//Triggered by the user clicking on the webpage
//There is a problem with QWebEngineView. When the user clicks a link in the webpage, it only triggers the urlChanged(QUrl) signal
//Does not automatically load new Linking web pages requires manual loading
void MainWindow::onUrlChanged(const QUrl &url)
{

//地址栏的旧网址
QUrl old = QUrl( m_pURLEdit->text() );
//链接有变化才更新，用户点击网页里的新链接会触发
if(url != old)
{
    m_pURLEdit->setText( url.toString() );
    //用户点击了新网页，但是没自动加载，手动刷新
    m_pView->load(url);//要放在if判断内部，否则容易无限刷新，死循环
}

qDebug()<<url;

}
