Master application development by writing succinct, robust, and reusable code with Qt 5

About This Book

• Unleash the power of Qt 5 with C++14
• Integrate useful third-party libraries such as OpenCV
• Package and deploy your application on multiple platforms

Who This Book Is For

This book will appeal to developers and programmers who would like to build GUI-based applications. Knowledge of C++ is necessary and the basics of Qt would be helpful.

What You Will Learn

• Create stunning UIs with Qt Widget and Qt Quick
• Develop powerful, cross-platform applications with the Qt framework
• Design GUIs with the Qt Designer and build a library in it for UI preview
• Handle user interaction with the Qt signal/slot mechanism in C++
• Prepare a cross-platform project to host a third-party library
• Build a Qt application using the OpenCV API
• Use the Qt Animation framework to display stunning effects
• Deploy mobile apps with Qt and embedded platforms

In Detail

Qt 5.7 is an application development framework that provides a great user experience and develops full-capability applications with Qt Widgets, QML, and even Qt 3D.

This book will address challenges in successfully developing cross-platform applications with the Qt framework. Cross-platform development needs a well-organized project. Using this book, you will have a better understanding of the Qt framework and the tools to resolve serious issues such as linking, debugging, and multithreading. Your journey will start with the new Qt 5 features. Then you will explore different platforms and learn to tame them. Every chapter along the way is a logical step that you must take to master Qt. The journey will end in an application that has been tested and is ready to be shipped.

Style and approach

This is an easy-to-follow yet comprehensive guide to building applications in Qt. Each chapter covers increasingly advanced topics, with subjects grouped according to their complexity as well as their usefulness. Packed with practical examples and explanations, Mastering Qt contains everything you need to take your applications to the next level.

About the Authors

Guillaume Lazar is a software engineer living near Paris in France. He has worked for different companies, from startups to multinationals, for the last 7 years. He took the opportunity to observe and learn from many team organizations and technologies.

He eventually founded his own software development company, NeuronalMotion, at the age of 27 with his friend Robin Penea in 2014. Information about it and its open source projects can be found on the comapny's website, www.neuronalmotion.com.

NeuronalMotion represents to Guillaume "a different way of working." The current hierarchical organization that applies to most companies seems obsolete to him. With his own company, he wants to try something different, where each employee will be autonomous.

Although he defines himself as a Qt framework lover, he likes to mix different technologies and platforms. He also spends time on game development, machine learning, and electronics, because "things" become "alive."

Creating examples and writing chapters for this book was a serious challenge this year. Some sections were fundamentally changed to match Qt evolution. I would not have been able to achieve this task alone. I wish to thank Robin Penea, my friend and the coauthor of this book. He gave his all to create with me a robust Qt book with modern C++. Our review team, Rohit Kumar Singh, Ray Rischpater, Quentin Canu, Chistophe Dongieux, and Hugo Loi, have done excellent work: they corrected us and raised some important issues. I also want to thank Packt for the good follow up during the writing process. Finally, I thank my family and, particularly, Sophie, my girlfriend, for her support.

Robin Penea is a software engineer living in France. He has worked for several companies over the last 7 years, on many different technologies (ranging from server application development to embedded programming).

He founded NeuronalMotion with Guillaume Lazar in 2014 to implement his vision of entrepreneurship and project development. He aims to achieve a self-organized company. More information is available at www.neuronalmotion.com.

Besides developing with Qt, he likes to tinker with the Android AOSP framework, learn new programming language paradigms, and discover how to interweave technology and real life.

This book would not have existed without Guillaume Lazar, my friend and the coauthor of the book. He was truly dedicated to designing and crafting the best possible book. I wish to thank our reviewers, Rohit Kumar Singh, Ray Rischpater, Quentin Canu, Christophe Dongieux, and Hugo Loi. Their input was invaluable and definitely raised the quality of the book. Packt played a sensible role, listening to our requests and changes, guiding us through the writing, and monitoring our mental states during this year with benevolence. I also wish to thank my father, Calin, for believing in me. A last word for Flore, my girlfriend, who kept my motivation up and supported me.

About the Reviewer

Ray Rischpater is a software engineer and author with over 20 years of industry experience and sixteen books to his credit. Beginning with software development for mobile platforms, he’s done work in several areas, including mobile, web services, building tools for mapping and geospatial engineering, and applying machine learning to geospatial processing problems.

During this time, he’s participated in the development of Internet technologies and custom applications for Newton, Magic Cap, Palm OS, Java ME, Qualcomm BREW, Apple iOS, and Google Android, as well as several proprietary platforms. Over the last six years, his focus has shifted from mobile applications and services to building tools, software processes, and machine learning models to facilitate mapping the real world. Presently, he’s employed as a software engineering manager at Uber, doing work on mapping and machine learning.

When not writing for or about software development, he enjoys making music, hiking, and photography with his family and friends in and around the San Lorenzo Valley in central California. When he’s able, he also provides public service through amateur radio as the licensed Amateur Extra station KF6GPE.

He is the author of Microsoft Mapping with Carmen Au, by Apress (published in 2013) and Application Development with Qt Creator, Second Edition, by Packt (published in 2014). He has written several other books, including Beginning Java ME Platform (Beginning from Novice to Professional), by Apress (published in 2008), Software Development for the QUALCOMM BREW Platform, by Apress (published in 2003), Wireless Web Development, First Edition, by Apress (published in 2002), and Wireless Web Development, Second Edition, by Apress (published in 2004).

I’d like to thank my wife, Meg Given, for her patience as I worked on yet another book project.
