Starting to learn a new platform can be daunting. Especially, when it is as big as the Mozilla platform. The XUL tutorial and reference were exactly what I needed to start learning. However, I quickly found myself wanting to experiment with little XUL snippets just to see what they looked like at runtime. Or, I’d want to try applying some CSS to the elements. I decided to build a XULRunner application that provided a simple way to experiment with XUL. It also gave me a good hands-on project I could use to really start learning the platform.
I made an install (Windows only) that includes XULRunner 188.8.131.52, so you have everything you need to start using it. I am working on Mac and Linux installs too, but for now you can download the source. I did not package the source into JAR files. I wanted the code to be easy to access, in case anyone wants to see how it works or show me better ways of doing things.
