I need to check user input in realtime. So when the user has entered more than for example 40 characters, he will be sent to the next line. I tried to use getText method in onKeyReleased method, but when the user hold the key, it can enter more than 40 characters. Sorry, maybe the explanation is not good enough.

6I recommend making it into a property and then add a listener to the property, then whenever it changes you can check if the length of input is > 40, then you can jump them to the next line. Hope that helpsZeldaZach– ZeldaZach2017-06-22 15:32:22 +00:00Commented Jun 22, 2017 at 15:32

Maybe what you are looking is something like that:
/* [Code...] */
@FXML
private void initialize() {
firstField.textProperty().addListener((observable, oldValue, newValue) -> {
if (newValue.length() > 40)
secondField.requestFocus();
});
}
/* [Code..] */
Need to do the changes on the Controller class. As Sendrick suggested on the link this.
