Clear prompt text in JavaFX TextField only when user starts typing

Question

The default behaviour is that the prompt text in the field is erased as the field is being focused. That is when the marker is in the field.

Is it possible to confi

Answer 1

Assuming you're setting prompt text via:

    @FXML TextField tf;

    public void someMethod() {
        tf.setPromptText("This is the prompt text");
    }

You can instead use tf.setText(String str) to set initial text.

Then, in the initialize method of your controller, add:

    tf.setOnKeyTyped(new EventHandler() {

        @Override
        public void handle(KeyEvent event) {
            tf.setText(null);

        }
    });
