问题 Are there any functional differences between QWebView and QWebEngineView? If I understand correctly, QWebView is webkit, while QWebEngineView is blink. Are there any differences to the programmer? Does one offer more customization of look & feel over the other? 回答1: I would give QtWebEngine a try. It is replacing QtWebKit for a reason.

问题 How to tell QWebPage not to load specific type of resources like js, css or png? 回答1: The solution is to extend QNetworkAccessManager class and override it's virtual method QNetworkAccessManager::createRequest In our implementation we check the path of the requested url and if it's the one we don't want to download we create and hand over an empty request instead of the real one. Below is a complete, working example. #include <QApplication> #include <QUrl> #include <QtWebKit/QWebPage>

问题 Both QWebFrame and QWebPage have void loadFinished(bool ok) signal which can be used to detect when a web page is completely loaded. The problem is when a web page has some content loaded asynchronously (ajax). How to know when the page is completely loaded in this case? 回答1: I haven't actually done this, but I think you may be able to achieve your solution using QNetworkAccessManager . You can get the QNetworkAccessManager from your QWebPage using the networkAccessManager() function.
