I've spent the last 2 days searching the net for an answer to this problem: How do you change the LookAndFeel of an application you are working on in Sun One Studio (or NetBeans)? Is it even supported in the IDE? Or can you only change the look and feel by editing the main or init methods?
This post talks about how you can set up a different default look & feel up for all your Java apps. The only time this wouldn't work is if an app loads a specific look and feel. So, if the IDE specifies a specific look & feel you'll still need to set your specific look & feel in the main() method like always. If you do set default look & feel like the post outlines, then all your java apps that use the default look and feel will use the new look and feel.
