TextArea ignore KeyEvent in JavaFX

问题

Java,JavaFX As in tittle, how can i force TextArea to ignore KeyEvent,and make sth instead of this KeyEvent. I should rather say that I would like to overwrite method which append a character from KeyEvent.

Fo example: If i click 'k' on keyboard in the TextArea i would like it to be printed in console (not appended to TextArea)

Friend, try this:

TextArea textArea = new TextArea();
textArea.addEventFilter(KeyEvent.KEY_TYPED, e -> {
    if (e.getCharacter().equals("k")) {
        e.consume();
    }
});

or:

TextArea textArea = new TextArea();
textArea.setOnKeyTyped(e -> {
    if (e.getCharacter().equals("k")) {
        e.consume();
    }
});
