Duke images here from previous dukes I posted and other images from Open Clipart Project.

Java Web Start:

The code:

package dukepotato;

import javafx.application.Frame;
import javafx.application.Stage;
import javafx.scene.CustomNode;
import javafx.scene.Node;
import javafx.scene.Group;
import javafx.input.MouseEvent;
import javafx.scene.geometry.Circle;
import javafx.scene.paint.Color;
import javafx.scene.image.ImageView;
import javafx.scene.image.Image;

public class Img extends ImageView{
    public  attribute content: Node[];
    public  attribute src: String;

    private attribute endX = 0.0;
    private attribute endY = 0.0;
    private attribute startX = 0.0;
    private attribute startY = 0.0;

    override attribute translateX = bind endX;
    override attribute translateY = bind endY;
    override attribute blocksMouse = true;

    init {
        image = Image {
            url: "{__DIR__}/{src}"
        }
    }

    override attribute onMousePressed = function(e:MouseEvent):Void {
        startX = e.getDragX()-endX;
        startY = e.getDragY()-endY;
    }

    override attribute onMouseDragged = function(e:MouseEvent):Void {
        endX = e.getDragX()-startX;
        endY = e.getDragY()-startY;
    }
}

var dukesimages = ["duke1.png", "duke2.png", "duke3.png", "duke4.png"];
var dukes = for (image in dukesimages){
    Image {
        url: "{__DIR__}/{image}"
    }
}
var index = 0;
var duke = ImageView {
    x: 200, y:170
    image: bind dukes[index];
    onMouseClicked: function( e: MouseEvent ):Void {
        index = (index + 1) mod sizeof dukesimages;
    }
}

var hat = Img { src: "hat.png", x: 370 }
var partyhat = Img { src: "party_hat.png", x: 160, y: 5 }
var cap = Img { src: "cap.png", x: 230, y: 10 }
var cake = Img { src: "cake.png", x: 526, y: 190 }
var glove = Img { src: "glove.png", x: 338, y: 363 }
var baseball = Img { src: "baseball.png", x: 548, y:373 }
var pencil = Img { src: "pencil.png", x: 451, y: 365 }
var camera = Img { src: "camera.png", x: 125, y: 380 }
var coffee = Img { src: "coffee.png", x: 541, y: 114 }
var burger = Img { src: "burger.png", x: 542, y: 282 }
var diamond = Img { src: "diamond.png", x: 243, y: 383 }
var pliers = Img { src: "pliers.png", x: 20, y: 368 }
var rubikcube = Img { src : "rubikcube.png", x: 37, y: 295 }
var syringe = Img { src: "syringe.png", x: 35, y: 245 }
var hourglass = Img { src: "hourglass.png", x: 35, y: 127 }
var adventurehat = Img { src: "adventurehat.png", x: 8, y:30 }
var tie = Img { src: "tie.png", x: 547, y:35 }

Frame {
    title: "Duke Potato"
    width: 640
    height: 480
    closeAction: function() {
        java.lang.System.exit( 0 );
    }
    visible: true

    stage: Stage {
        content: [duke, hat, partyhat, cake, adventurehat, cap, glove,
            baseball, pencil, camera, coffee, burger, diamond,
            pliers, rubikcube, syringe, hourglass, tie]
    }
}

Lines 14 to 42 is the same dragging approach I showed in the post Draggable Nodes, but this time creating a class that inherits the behavior of ImageView.
Lines 44 to 57 is the Duke that changes when you click on it. It cycles over the dukesimages list.
Lines 59 to 75 is just instantiations of all toys and objects we will use to dress the Duke. Look how easier was to create and place a image.
Lines 78 to the end is just creating a Frame and putting all elements on it.

Download a package with the NetBeans project, sources, libraries and images, DukePotato.tar.gz.
