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.

Summary

In this chapter, we took a whirlwind tour of the Qt Widgets module. We learned about some of the basic widgets available, and the signals, slots, and properties they provide. We also learned about Qt's application of the MVC paradigm and how, for complex widgets like such as and tree views, Qt separates concerns into a model and a view, letting us implement new data models for our applications, or create new views based on those data models. Then, we learned about Qt's support for the WebEngine browser, letting us build hybrid applications that incorporate the best of JavaScript and HTML with the best of Qt. Finally, we learned about the new additions to Qt Widgets and how they help in application development and language support.

In the next chapter, we move on from widgets to low-level drawing, which we can use to either implement our own widgets or basic pixel...
