Groovy.swing.SwingBuilder

Swingbuilder is a DSL that makes constructing Swing interfaces much easier to use than when using them in Java

Example

This example script creates a frame with a scrolling textarea and a button.

import java.awt.*
import groovy.swing.SwingBuilder
import java.awt.BorderLayout

def BL = new BorderLayout()

def swing = new SwingBuilder()
    frame = swing.frame(title:'Frame', size:[300,300], layout:new BorderLayout()) {
        scrollPane(constraints:BL.CENTER){
            textArea()
        }  
        panel(constraints:BL.SOUTH){
            button(text:"Hello", actionPerformed:{println "Hello"})
        }
    }

    frame.show()
