This is not the Ultimate Scripting Language

We had to write libraries to hide the direct Javadot access.

(load "jlib/Swing.scm") ;a little functional language for GUI creation

(define w 
  (window "Test"
    (button "exit" red 
            (action(lambda(e)(exit))))))
(.pack w) 
(.show w)

Resulting code is much simpler than straight JScheme + javadot

(import "javax.swing.*")
(define w (JFrame. "Test"))
(define eb (JButton. "Exit"))
(.setBackground eb Color.red$)
(.addActionListener eb 
   (Listener. (lambda(e) (System.exit 0))))
(.add (.getContentPane w) eb) 
(.pack w) (.show w)
