javafx Bindings.createStringBinding but binding not actually work

Question

I\'m trying to bind the textProperty of the Label to the object\'s SimpleIntegerProperty with help of Bindings but it does no

Answer 1

You need to "tell" Bindings, which Observables to observe for changes. This varargs parameter is the second parameter of the createStringBinding method. In this case you need to pass only a single Observable: object.numberProperty()

label.textProperty().bind(
   Bindings.createStringBinding(
      () -> " hello " + object.numberProperty().get() * (10 + 12)/2,
      object.numberProperty()));
