Or perhaps you just want to add a simple graphical interface to that clumsy command-line utility. No matter the goal, developers regularly look to the open source toolkit known as GTK+ to build sophisticated graphical interfaces. But learning how to effectively use GTK+ can be a daunting task. Some features can be difficult to understand, and online documentation is often scant. Figuring out where to begin may be even trickier, since GTK+ depends on so many libraries. For these reasons, I decided to write a practical guide to GTK+ development. Because so many newcomers struggle with simply getting started using GTK+, I thought it appropriate to dirty your hands as quickly as possible. After devoting Chapter 1 to an overview of key concepts, I will show you how to create, compile, and execute your first application. The chapters that follow introduce you to the wide variety of widgets and signals at your disposal, which embody your application’s look and behavior respectively. To cement your knowledge, along the way we will create several interesting applications such as a file browser and a text editor. By the time you complete the last chapter, you will be able to implement very complex GUI applications. I wrote this book to be not only a practical tutorial but also a reasonably complete reference. To that end, I’ve included an extensive array of appendixes covering object properties, widget signals, style properties, stock items, and GError types; the information they contain will become indispensable as you begin writing your own applications.
