import groovyx.javafx.SceneGraphBuilder

GroovyFX.start({
    def sg = new SceneGraphBuilder();

    sg.stage(title: "Gradient Example (GroovyFX)", width: 1020, height: 450, visible: true) {
        scene(fill: linearGradient(endX: 0, stops: [[0.0, white], [1.0, lightgray]])) {

            def width = 240
            def height = 180

            rectangle(width: width, height: height,
                fill: linearGradient(stops:[[0.0, red],[1.0, black]]),
