Usage

From source file:Main.java

@Override
public void start(Stage stage) {
    Group p = new Group();
    Scene scene = new Scene(p);
    stage.setScene(scene);/*from  ww w .  j  av  a2 s. c o  m*/
    stage.setWidth(500);
    stage.setHeight(500);
    p.setTranslateX(80);
    p.setTranslateY(80);

    //create a circle with effect
    final Circle circle = new Circle(20, Color.rgb(156, 216, 255));
    circle.setEffect(new Lighting());
    //create a text inside a circle
    final Text text = new Text(i.toString());
    text.setStroke(Color.BLACK);
    //create a layout for circle with text inside
    final StackPane stack = new StackPane();
    stack.getChildren().addAll(circle, text);
    stack.setLayoutX(30);
    stack.setLayoutY(30);

    p.getChildren().add(stack);
    stage.show();

    //create a timeline for moving the circle
    timeline = new Timeline();
    timeline.setCycleCount(Timeline.INDEFINITE);
    timeline.setAutoReverse(true);

    //You can add a specific action when each frame is started.
    timer = new AnimationTimer() {
        @Override
        public void handle(long l) {
            text.setText(i.toString());
            i++;
        }
    };

    //create a keyValue with factory: scaling the circle 2times
    KeyValue keyValueX = new KeyValue(stack.scaleXProperty(), 2);
    KeyValue keyValueY = new KeyValue(stack.scaleYProperty(), 2);

    //create a keyFrame, the keyValue is reached at time 2s
    Duration duration = Duration.millis(2000);
    //one can add a specific action when the keyframe is reached
    EventHandler onFinished = new EventHandler<ActionEvent>() {
        public void handle(ActionEvent t) {
            stack.setTranslateX(java.lang.Math.random() * 200 - 100);
            //reset counter
            i = 0;
        }
    };

    KeyFrame keyFrame = new KeyFrame(duration, onFinished, keyValueX, keyValueY);

    //add the keyframe to the timeline
    timeline.getKeyFrames().add(keyFrame);

    timeline.play();
    timer.start();
}
