Java: July 2008 Archives

In anticipation of the JavaFX SDK preview release, I have whipped up a very primitive JavaFX Script brush for Syntax Highlighter. Adding the brush is easy, so I will not bore you with boilerplate. Include the brush, set your code class to "jfx", and you get nicely highlighted JavaFX Script code on your blog!

Download the brush here: http://coffeejolts.com/downloads/shBrushJavaFX.js

Here is a sample from James Weaver's blog, highlighted using my brush:
