Cross-Platform App Development with Qt 5: A Beginner's Guide

The Qt framework is a cross-platform application framework and widget toolkit used to create graphical user interface (GUI) applications that can run on different hardware and operating systems. This book aims to introduce Qt to the reader, guiding them through the building blocks using simple examples, without excessive focus on theory.

Qt is a popular tool employed in the development of various applications, such as web browsers, media players like VLC, and Adobe Photoshop. After covering the installation and setup of Qt, the book delves into the creation of your first application.

You will be introduced to Widgets, Qt's interface building blocks, and the numerous varieties available for creating GUIs. The book then thoroughly illustrates Qt's core concept of signals and slots, providing ample examples. You will learn how to create custom widgets, signals and slots, and how to communicate useful information via dialog boxes. Finally, you will be guided through the process of writing applications that can connect to databases to persist data.

By the end of the book, you should be well-equipped to start creating your own Qt applications and feel confident enough to explore more advanced Qt techniques and materials to further hone your skills.
