Displaying changing values in JavaFx Label

Question

In JavaFX, how can I display values which continuously change with time using "label" ?

Answer 1

There are numerous ways to achieve that, the most convenient would be to use JavaFX's DataBinding mechanism:

// assuming you have defined a StringProperty called "valueProperty" Label myLabel = new Label("Start"); myLabel.textProperty().bind(valueProperty); 

This way, every time your valueProperty gets changed by calling it's set method, the label's text is updated.

Answer 2

How about using SimpleDateFormat? There's no need for the StringUtilities class!

private void bindToTime() {   Timeline timeline = new Timeline(     new KeyFrame(Duration.seconds(0),       new EventHandler<ActionEvent>() {         @Override public void handle(ActionEvent actionEvent) {           Calendar time = Calendar.getInstance();           SimpleDateFormat simpleDateFormat = new SimpleDateFormat("HH:mm:ss");           setText(simpleDateFormat.format(time.getTime()));         }       }     ),     new KeyFrame(Duration.seconds(1))   );   timeline.setCycleCount(Animation.INDEFINITE);   timeline.play();  } }
