Copy / Paste Events

Question

Hello All,
I have a textfield that checks text inputs with:
@FXML protected void keyTyped(KeyEvent event) {
         System.out.println("keypressed " + event.getCharacter());
         if(textFieldName.getCharacters().length() >= 30) {
             textFieldName.deletePreviousChar();
             lenghtWarning.setVisible(true);
         else {
             lenghtWarning.setVisible(false);
     }How can I detect a paste event by the context menu or CTR v ?
Which listener should I use to catch copy / paste events?

Answer 1

I've used the textProperty().addListener for that (it restricts the TextField to a maxlength of 30):
textProperty().addListener(new ChangeListener<String>() {
            private boolean ignore;
            @Override
            public void changed(ObservableValue<? extends String> observableValue, String s, String s1) {
                if (ignore || s1 == null)
                    return;
                if (s1.length() > 30) {
                    ignore = true;
                    setText(s1.substring(0, 30));
                    ignore = false;
        });
