Mastering GUI Programming with Python

Using the QWebEngineView widget

We need to make a copy of our Qt application template from Chapter 4, Building Applications with QMainWindow, and call it simple_browser.py; we're going to develop a rudimentary browser with tabs and a history display.

We start by importing the QtWebEngineWidgets library as follows:

from PyQt5 import QtWebEngineWidgets as qtwe

Note that there is also a QtWebEngine module, but it is for use with the Qt Modeling Language (QML) declarative framework, not the Qt Widgets framework covered by this book. QtWebEngineWidgets contains the widgets-based browser.

In our MainWindow class constructor, we'll start the GUI by defining a navigation toolbar:

        navigation = self.addToolBar('Navigation')        style = self.style() self.back ...
