Event-Driven GTK by Example — 2021 Edition is a comprehensive guide to building graphical user interfaces (GUIs) using the popular GTK toolkit. GTK is a powerful open-source toolkit that is widely used in the Linux and Unix communities. With its C-based programming interface and object-oriented design, GTK is an excellent choice for building cross-platform desktop applications.

This book is designed to provide a practical introduction to event-driven programming with GTK. It takes a hands-on approach, with plenty of example code and step-by-step tutorials that walk you through the process of building your own GUIs. Whether you’re new to GTK or an experienced developer looking to expand your skills, this book will help you get up to speed quickly.

The book begins by introducing the basics of GTK programming, including the layout and design of GTK applications. From there, it dives into the heart of event-driven programming, showing you how to handle user events such as mouse clicks and keystrokes. You’ll learn how to create event handlers and callbacks, and how to use signals and slots to connect your GUI to your application logic.

One of the strengths of GTK is its support for a wide range of widgets, from basic buttons and text fields to more complex objects like trees and grids. This book covers all the major widgets in detail, showing you how to use them to create a variety of GUIs. You’ll also learn how to customize the appearance and behavior of widgets using style sheets and other advanced techniques.

Throughout the book, the author emphasizes best practices for GTK programming, such as modular design and separation of concerns. You’ll learn how to organize your code into reusable components, and how to build robust applications that can handle errors and exceptions gracefully.

In summary, Event-Driven GTK by Example — 2021 Edition is an excellent resource for anyone interested in building powerful and flexible GUIs with GTK. With its clear explanations, practical examples, and emphasis on best practices, this book will help you become a proficient GTK programmer in no time.
