In my unreleased MOSS stuff, I have a Swing app that has a JSplitPane with a JSplitPane in it because I wanted a center JME window with Swing controls to the left and right. I remember something about the event updating and doing things a frame later or something. Anyway, here is the source code for the relevant parts.
Hopefully you can read around the app-specific parts and see something different that I’m doing.
