JavaFX 2 Loading Indicator

A simple way to create a loading indicator in JavaFX 2.

Code:

 
import javafx.animation.KeyFrame;
import javafx.animation.KeyValue;
import javafx.animation.Timeline;
import javafx.beans.property.DoubleProperty;
import javafx.beans.property.SimpleDoubleProperty;
import javafx.scene.Parent;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.scene.text.Text;
import javafx.util.Duration;

public class LoadingIndicator extends Parent{
    
    private Timeline timeline = new Timeline();
    
    private DoubleProperty stroke = new SimpleDoubleProperty(100.0);
    
    
    public LoadingIndicator(){
        super();
        
        timeline.setCycleCount(Timeline.INDEFINITE);
        
        final KeyValue kv = new KeyValue(stroke, 0);
        final KeyFrame kf = new KeyFrame(Duration.millis(1500), kv);
        
        timeline.getKeyFrames().add(kf);
        timeline.play();        
        
        VBox root = new VBox(3);
        
        StackPane progressIndicator = new StackPane();
        
        Rectangle bar = new Rectangle(350,13);
        bar.setFill(Color.TRANSPARENT);
        bar.setStroke(Color.WHITE);
        bar.setArcHeight(15);
        bar.setArcWidth(15);
        bar.setStrokeWidth(2);
        
        Rectangle progress = new Rectangle(342,6);
        progress.setFill(Color.WHITE);
        progress.setStroke(Color.WHITE);
        progress.setArcHeight(8);
        progress.setArcWidth(8);
        progress.setStrokeWidth(1.5);
        progress.getStrokeDashArray().addAll(3.0,7.0,3.0,7.0);
        progress.strokeDashOffsetProperty().bind(stroke);
        
        
        progressIndicator.getChildren().add(progress);
        progressIndicator.getChildren().add(bar);
        
        root.getChildren().add(progressIndicator);
        
        Text label = new Text("Loading...");
        label.setFill(Color.WHITE);
        
        root.getChildren().add(label);
        
        getChildren().add(root);
        
    }
    
}
