Overview of this book

Qt 5, the latest version of Qt, enables you to develop applications with complex user interfaces for multiple targets. It provides you with faster and smarter ways to create modern UIs and applications for multiple platforms. This book will teach you to design and build graphical user interfaces that are functional, appealing, and user-friendly. In the initial part of the book, you will learn what Qt 5 is and what you can do with it. You will explore the Qt Designer, discover the different types of widgets generally used in Qt 5, and then connect your application to the database to perform dynamic operations.

You will also work with various Qt modules, like QtLocation, QtWebEngine, and the networking module through the course of the book. Finally, we will focus on cross-platform development with QT 5 that enables you to code once and run it everywhere, including mobile platforms. By the end of this book, you will have successfully learned about high-end GUI applications and will be capable of building many more powerful, cross-platform applications.

Introduction to Qt

Qt (pronounced cute) has been used by software engineers and developers for more than two decades to create cross-platform applications since its first release. After several changes of ownership and numerous major code overhauls, Qt has become even more feature rich and supports even more platforms than it used to. Qt not only excels in desktop application development, but is also excellent for both mobile and embedded systems development.

In this chapter, we will cover the following topics :

  • What is Qt?
  • Why use Qt?
  • Using tools in Qt
  • Downloading and installing Qt
  • Setting up a working environment
  • Running our first Hello World Qt program

Throughout this chapter, we will learn more about the history of Qt. Then, we'll proceed to build our first example program using the latest version of Qt, which is Qt version 5. For the convenience of our readers, we will simply refer to it as Qt throughout the book.
