JavaFX TextArea onChange event


Good day developers :)

Does JavaFX component, TextArea, have support for some event like onTextChange or similar? Yes, I know for keyPressed, keyTyped ... but how to handle event if another "action" do changes on TextArea (eg. txArea.setText("some text")).

As with all of JavaFX, just add a listener to the TextArea textProperty().

This is the code:

textArea.textProperty().addListener(new ChangeListener<String>() {
    public void changed(final ObservableValue<? extends String> observable, final String oldValue, final String newValue) {
        // this will run whenever text is changed
