JavaFX binding Label with int value

Question

I want to bind JavaFX Label.textProperty with int value.

I tried e.g.

Label.textProperty().bindBidirectional(new SimpleIntegerProperty(myInt), 
                                                      new NumberStringConverter());

or

Label().textProperty().bindBidirectional(new SimpleIntegerProperty(myInt), 
                                                              new DecimalFormat());

But I always get NullPointerException.

How can I fix it?

Answer 1

If you have an int you can create a SimpleIntegerProperty from it and then use the asString() on it :

label.textProperty().bind(new SimpleIntegerProperty(integer).asString());

If you have an IntegerProperty, you can directly use it

label.textProperty().bind(integerProperty.asString());
