Overview of this book

Qt is a cross-platform application framework and widget toolkit that is used to create GUI applications that can run on different hardware and operating systems. The main aim of this book is to introduce Qt to the reader. Through the use of simple examples, we will walk you through building blocks without focusing too much on theory. Qt is a popular tool that can be used for building a variety of applications, such as web browsers, media players such as VLC, and Adobe Photoshop. Following Qt installation and setup, the book dives straight into helping you create your first application. You will be introduced to Widgets, Qt's interface building block, and the many varieties that are available for creating GUIs. Next, Qt's core concept of signals and slots are well illustrated with sufficient examples. The book further teaches you how to create custom widgets, signals and slots, and how to communicate useful information via dialog boxes. To cap everything off, you will be taken through writing applications that can connect to databases in order to persist data. By the end of the book, you should be well equipped to start creating your own Qt applications and confident enough to pick up more advanced Qt techniques and materials to hone your skills.

Summary

This chapter laid the foundation for getting to know Qt and what it can be used for. Installing of Qt on macOS and Linux was outlined. A small hello world application was written and compiled, all from the command line, without any need for an IDE. This meant that we were also introduced to the various steps that lead to the final program.

Finally, the hello world application was modified to employ QSS in a bid to show what other things can be done to a widget.

In Chapter 2, Creating Widgets and Layouts, we will explore more widgets in Qt and how to organize and group them.
