JavaFX 2.0 – NodeCodeEditor

As I previously said I am working on a Software Component Editor. Transforming my inkscape visual prototype to my FX Application was quiet easy thanks to JavaFX SVGPath. At least for the shape contour, but I had another problem to solve to manage gradient.

So I started groping around JavaFx Gradient paint (RadialGradient and LinearGradient). Modifying and launching again and again to adjust my gradient attributes change. And then I get bored… I mean, It was about to take me a whole life making theses adjustments !

Thinking about it I remembered the way prototypes are built in my company, using SmallTalk language and performing changes on code on the editor that is taken into account as soon as they are “accepted”. Well I can do that too ! Thanks to Eclipse IDE debug mode. The only constraint was to have no structural change in my code and finding a way to have a loop that will take into account all changes on my JavaFX graphical Application.

Please welcome my little NodeEditionVisualizer ! It is simply a JavaFX Application that loop on a method call that draw a user created Node continuously. It has to be launched in debug mode so that changes are taken into account when you save. It is composed of an X/Y axis and a user created Node that can be changed dynamically.

protected ScheduledThreadPoolExecutor executor = new ScheduledThreadPoolExecutor(1);
public static void main(String[] args) {
	public void start(final Stage primaryStage) throws Exception {
		final Group pane = new Group();
		Scene scene = new Scene(pane);
		primaryStage.setTitle("C3 Shape Editor");
		final Path axis = PathBuilder.create().elements(
			new MoveTo(0, 0),
			new LineTo(0, 100),
			new LineTo(-10, 90),
			new MoveTo(0, 100),
			new LineTo(10,90),
			new MoveTo(0, 100),
			new LineTo(0, 3000),
			new MoveTo(0, 0),
			new LineTo(100, 0),
			new LineTo(90, -10),
			new MoveTo(100, 0),
			new LineTo(90, 10),
			new MoveTo(100, 0),
			new LineTo(3000, 0)).stroke(Color.WHITE).build();
		final Text origin = TextBuilder.create()
		final Text x = TextBuilder.create()
		.text("X Axis").fill(Color.WHITE).x(50).y(-5)
		final Text y = TextBuilder.create()
		.text("Y Axis").fill(Color.WHITE).x(-25).y(70).rotate(-90)
		this.executor.scheduleAtFixedRate(new Runnable(){
			public void run() {
				Platform.runLater(new Runnable(){
					public void run() {
						Node dut = createShape();
						pane.getChildren().addAll(dut, axis, origin, x, y);
		}, 200, 200, TimeUnit.MILLISECONDS);
		primaryStage.setOnCloseRequest(new EventHandler() {
			public void handle(WindowEvent paramT) {
	public Node createShape(){
		Rectangle rectangle = RectangleBuilder.create()
                Circle circle = CircleBuilder.create()
                return new Group(circle, rectangle);

As usual, code is available in a jar on download page.

Feel free to reuse this code ! If you have some suggestions, I would be glad to take them into account !


JavaFx 2.0 – SVGPath

I start developing a new application for a software components editor (more informations soon). So I built my visual using Inkscape (as usual). Then I asked myself how to import my svg objects into JavaFx. I saw Inkscape does offer to export your svg into JavaFx code, but for now only JavaFx1.3 script is supported, so unable to do it for  my JavaFX2.0 business application… Well I was only half tempted by writing a JavaFX1.3 to JavaFX2.0 code converter…

What a good suprise to discover the SVGPath object in JavaFx ! It made my import work quite easy (not easier than if Inkscape generated it for me but….). I just use the Inkscape objects xml editor to copy the path informations as shown :

Then juste create a JavaFx SVGPath Object and fill the content attribute with what you’ve copied

And Here you are with your SVG interface work into your business JavaFx code ! Take care that positions of the SVG Object path points from Inkscape are relative to the top/left corner of your page.

I did not find out how to easily transform your SVG object fill information as available in the Inkscape xml editor into JavaFx. I might think of writing a small parser program that compute such information into code… For now I translated myself the fill information using JavaFx Painter.

If some of you have interesting informations about SVGPath in JavaFx, raise your hand !

Design – Inkscape #2

Today an other drawing that is a realization of a great tutorial that is very well explained. I’m glad to discover Inkscape capabilities like filters, dynamic offsets, circular gradient effects… If you want to discover some inkscape tricks, try this tut !

Contrary to the previous Design post this realization is done from scratch, no input images. I might find time to propose an other little draw soon. I’m currently working at a small well known card game on Android platform. Coming soon !


Design – Inkscape

At work one of the new activity is to propose new design innovation (and more) to customer for next HMI oriented application. I’ve always been impressed by design art. I decided to try drawing and doing design myself. Today I post my first design activity, using Inkscape. Inkscape is an Open Source vector graphics editor.

After a first step learning how to use Inkscape basic functions (many thanks to PLA for the short morning lessons…), I decided to try doing more complete tutorials. So the result I present here is an Inkscape version of the photoshop tutorial you can find here. I did not want to insert the woman in my version because this photo is copyrighted…

I will go on trying to do some design, tutorial to learn but own creations as well… My next work may be to propose a new skin for this blog !
