Overview of this book

Qt 5.11 is an app development framework that provides a great user experience and develops full capability applications with Qt Widgets, QML, and even Qt 3D. Whether you're building GUI prototypes or fully-fledged cross-platform GUI applications with a native look and feel, Mastering Qt 5 is your fastest, easiest, and most powerful solution. This book addresses various challenges and teaches you to successfully develop cross-platform applications using the Qt framework, with the help of well-organized projects. Working through this book, you will gain a better understanding of the Qt framework, as well as the tools required to resolve serious issues, such as linking, debugging, and multithreading. You'll start off your journey by discovering the new Qt 5.11 features, soon followed by exploring different platforms and learning to tame them. In addition to this, you'll interact with a gamepad using Qt Gamepad. Each chapter is a logical step for you to complete in order to master Qt. By the end of this book, you'll have created an application that has been tested and is ready to be shipped.

Get Your Qt Feet Wet

If you know C++ but have never touched Qt, or if you have already made some intermediate Qt applications, this chapter will ensure that your Qt foundations are solid before studying advanced concepts in the following chapters.

We will teach you how to create a simple todo application using Qt Creator. This application will display a list of tasks that you can create/update/delete. We will cover the Qt Creator and Qt Designer interfaces, an introduction to the signal/slot mechanism, the creation of a custom widget with custom signals/slots, and its integration into your application.

You will implement a todo app using new C++14 semantics: lambdas, auto variables, and for loops. Each of these concepts will be explained in depth and will be used throughout this book.

By the end of this chapter, you will be able to create a desktop application with a flexible UI using Qt widgets and new C++ semantics.

In this chapter, we will cover the following topics:

  • Qt project basic structure
  • MainWindow structure
  • Qt Designer interface
  • Signals and slots
  • Custom QWidget
  • C++14 lambda, auto, and for each
