Creating Rainbox Plug-insThe JavaDoc is here. Here's a sample shape, clear, and color scheme. FYI the API uses abstract classes instead of interfaces so that I can add methods in the future without breaking existing extensions. Also – if you want your plugin to run in IE's Java, you can only use Java 1.1. (No Swing and no Collections!) To run your plugin in Rainbox, download the Rainbox JAR and save it somewhere. Then run Rainbox using a command like this: java -cp rainbox.jar;c:\MyRainboxPluginDirectory -Drainbox.clears=MyClear,MyClear2 -Drainbox.shapes=com.me.SomeShape -Drainbox.schemes=MyScheme net.alexrosen.rainbox.RainboxOr, if you're on Windows and want to test it with the Microsoft VM, to ensure that your plugin will work with IE, do this: jview /vst /cp rainbox.jar;c:\MyRainboxPluginDirectory -D:rainbox.clears=MyClear,MyClear2 -D:rainbox.shapes=com.me.SomeShape -D:rainbox.schemes=MyScheme net.alexrosen.rainbox.Rainbox |
