Foundations of GTK+ Development

Dear Reader,

Maybe you have a great idea for the world’s next killer application. 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.

I dedicate this book to Mrs. Kaminsky, for never allowing me to settle for anything but my

best. I hope you can look at this book and see everything that you have done for me,

even though I have yet to broaden the scope of my writing beyond technology.
