Re: Creating a groovy method in a java parent class for Thicky

I'm confused as to what you're asking - what you describe all looks 
fine. Java and groovy methods are the same thing.

Firstly should your Page be-a Panel or just have-a panel? It might be 
cleaner to just create any Swing component as part of the body() method 
rather than extending from a JPanel as you'll end up with an extra, 
pointless panel per page otherwise.

Maybe you just need border support in SwingBuilder?

There's always normal groovy code?

import javax.swing.border.*

...

body() {
     panel(border:new TitledBorder("hey"))
}

etc
