JavaFX bind to multiple properties

Question

I have a simple fxml with a textfield and a button. I\'d like to have the button disabled if the textfield is empty. So I insert something like the following in my controlle

Answer 1

In addition to martin_dk answer, if you want to bind more than two properties you will get code like below, looks weird, but it works.

BooleanBinding booleanBinding
        = finalEditor.selectedProperty().or(
                staticEditor.selectedProperty().or(
                        syncEditor.selectedProperty().or(
                                nativeEditor.selectedProperty().or(
                                        strictEditor.selectedProperty()))));

abstractEditor.disableProperty ().bind(booleanBinding);

Answer 2

This is possible by binding to a boolean expression via Bindings:

button.disableProperty().bind(
    Bindings.and(
        textField.textProperty().isEqualTo(""),
        textField2.textProperty().isEqualTo("")));

Answer 3

In addition to Andreys approach, I found that you can also do it like this:

    BooleanBinding booleanBinding = 
      textField.textProperty().isEqualTo("").or(
        textField2.textProperty().isEqualTo(""));

    button.disableProperty().bind(booleanBinding);
