Kivy Part 32 – Kivy ids

Today we’ll learn how to reference widgets using ids in Kivy. We’ll make use of the two test files again.

I just published my Kivy book, GUI Programming with Python and Kivy. It’s pretty long (over 800 pages) and comprehensive. And, which also counts, easy to read. The book contains lots of illustrations.

This book covers all the basics that you need to know to start programming GUI applications with Python and Kivy. Throughout the book we will be building a GUI application from scratch, a fully functional game using all kinds of tools that Kivy has to offer.

Each part of the book starts with a theoretical introduction of a topic or idea that we then implement in the project. I assume you have no prior knowledge of the Kivy library, but you should have at least some basic knowledge of the Python programming language, including the object-oriented programming paradigm as this is what we will be using a lot in this book.

The book covers all the basic elements of Kivy that you have to know, like widgets, layouts, Kivy ids and properties, graphics, screens, animation, sound. Finally we’ll deploy the app to Windows. It is pretty comprehensive and after you finish it, I’m sure you’ll be able to create your own awesome GUI apps of any kind, not just games.

I hope you will have at least as much fun reading the book as I had writing it.
