The primary class used from QtWebEngineWidgets is the QWebEngineView class; this class provides a nearly complete Chromium-based browser in a QWidget object. Chromium is the open source project that underpins much of Google Chrome, the newest versions of Microsoft Edge, and many other browsers.
Qt also has a deprecated QtWebKit module based on the Webkit rendering engine used in Safari, Opera, and some older browsers. There are some significant differences between the API and the rendering behavior of QtWebKit and QtWebEngineWidgets, with the latter being preferred for newer projects.
In this section, we'll see how easy it is to include web content in your Qt application by building a simple web browser using QtWebEngineWidgets.
