Application Development with Qt Creator - Third Edition

By: Lee Zhi Eng, Ray Rischpater

Overview of this book

Qt is a powerful development framework that serves as a complete toolset for building cross-platform applications, helping you reduce development time and improve productivity. Completely revised and updated to cover C++17 and the latest developments in Qt 5.12, this comprehensive guide is the third edition of Application Development with Qt Creator. You'll start by designing a user interface using Qt Designer and learn how to instantiate custom messages, forms, and dialogues. You'll then understand Qt's support for multithreading, a key tool for making applications responsive, and the use of Qt's Model-View-Controller (MVC) to display data and content. As you advance, you'll learn to draw images on screen using Graphics View Framework and create custom widgets that interoperate with Qt Widgets. This Qt programming book takes you through Qt Creator's latest features, such as Qt Quick Controls 2, enhanced CMake support, a new graphical editor for SCXML, and a model editor. You'll even work with multimedia and sensors using Qt Quick, and finally develop applications for mobile, IoT, and embedded devices using Qt Creator. By the end of this Qt book, you'll be able to create your own cross-platform applications from scratch using Qt Creator and the C++ programming language.

Rendering web content with QWebEngineView

Qt includes a port of WebEngine, the popular browser implementation behind Chromium and several open source browsers, in its Qt WebEngine module. Using the Qt WebEngine module, your application can display rich HTML, or even be a full-fledged web browser on its own. It's very easy to create hybrid applications that incorporate both features of native applications and the ability to display web content from local resources, the local filesystem, or the internet.

Do note that the Qt WebEngine module only works on MSVC compilers. You will get an error if you use other compilers.

To use the Qt WebEngine module, you must include it in your application by adding the following to your PRO file:

QT += webenginewidgets 

Any source file that accesses the Qt WebEngine widget's classes should also include the interfaces with the following...
