How to set ImageJ Look and Feel at startup

Hey guys,

I’ve been able to set most of my desired options in the startup macro for ImageJ. I want to set my look and feel from the default Metal to GTK+ when I start ImageJ, but I don’t quite know which command to use. The macro recorder doesn’t track it, and I can’t find any documentation on this.
Anyone know a solution? It’s just an optical improvement so my world won’t end if this isn’t possible. But it would be nice : )

Best regards
