Qt WebEngine Widgets gives you a Web browser engine that you can use to embed content easily from the World Wide Web into your Qt application.

Qt WebEngine Widgets lets you display HyperText Markup Language version 5 (HTML5), Extensible HyperText Markup Language (XHTML) and Scalable Vector Graphics (SVG) documents, styled using Cascading Style Sheets (CSS) and scripted with JavaScript.

HTML and XHTML documents can also be made fully editable to the user by using the contenteditable attribute on HTML elements.

Qt WebEngine is based on the Chromium project. See the Chromium Project Web site for more information.

Including In Your Project

To include the definitions of the module's classes, use the following directive:

#include <QtWebEngineWidgets>

To link against the module, add this line to your qmake .pro file:

QT += webenginewidgets

Architecture

Use the QWebEngineView class to display web pages in the simplest way. Because it's a widget, you can embed QWebEngineView into your forms and use its convenience functions to download and display web sites.

    QWebEngineView *view = new QWebEngineView(parent);
    view->load(QUrl("http://qt-project.org/"));
    view->show();

An instance of QWebEngineView has one QWebEnginePage. QWebEnginePage provides access to the page's navigation history, ability to run JavaScript code in the context of the page's main frame, and enables customization of handlers for specific events like showing custom authentication dialogs.
