Kivy is an open source Python library for rapid development of applications that make use of innovative user interfaces, such as multi-touch apps. The Kivy organization is organizing its second application development contest.! This is a great chance for new and experienced users to show off their skills and compete for prizes. Entries will be judged on a range of criteria accessible to both new and experienced programmers, so don’t be afraid to dive in! For more information, visit http://kivy.org/#contest

I recently received a copy of Kivy: Interactive Applications in Python by Roberto Ulloa. This is currently the only book about Kivy. Kivy is a cross-platform GUI toolkit that will run on Linux, Windows, and OS X as well as Android and iOS. In fact, the people behind Kivy emphasize that this is aimed primarily at mobile programming. Kivy supports multitouch and has a very active group of programmers. You can read more about Kivy on their project’s home page. I will be reviewing the PDF version of the book.
Here’s my quick review for those of you without a lot of time:
- Why I picked it up: I received this book as payment for helping with the reviewing of another Packt book, but I would have bought it myself because I am interested in learning Python for Android/iOS and I like learning about Python GUI toolkits.
- Why I finished it: The book is short and I was optimistic that it would get better.
- I’d give it to: Someone who already knows Python and the basics of Kivy, although I don’t think I would recommend it.

Recently I’ve started learning about Kivy, a Python Natural User Interface (NUI) toolkit. As I understand it, Kivy is kind of a spiritual successor to pyMT, which you can read more about here. In this article, we will be learning how Kivy handles layout management. While you can position widgets using x/y coordinates, in every GUI toolkit I’ve used, it’s almost always better to use some kind of layout management that the toolkit provides. This allows the widgets to resize and move appropriately as the user changes the window’s size. In Kivy, these things Layouts. If you’ve used wxPython, they are analogous to wxPython’s sizers.
I should also note that Kivy can do layouts in two different ways. The first way is to do Layouts with Python code only. The second way is to use a mixture of Python and Kv language. This is to promote the model-view-controller way of doing things. It looks kind of like CSS and reminds me a little of wxPython and XRC. We will look at how to use both methods in this article. While Kivy supports multiple types of Layouts, this article will be focusing only on the BoxLayout. We will show how to nest BoxLayouts. (more…)

I like to use Wingware’s IDE for coding in Python. I am working through some sample applications with Kivy, a cross-platform Python GUI framework that can also create UIs for mobile. Anyway, getting Kivy set up in Wing is slightly confusing, so here’s a crash course:
- Download Kivy
- Unzip Kivy somewhere. In my case, I unzipped it here: C:\kivy1.7.2\
- Run kivy.bat which is in the directory you unzipped to. You should see something like the following
