TextArea忽略JavaFX中的KeyEvent
问题描述：
Java，JavaFX 就像标题中一样，我如何才能强制TextArea忽略KeyEvent，而不是代替此KeyEvent.我想说的是，我想覆盖从KeyEvent追加字符的方法.
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.
示例:如果我在TextArea中的键盘上单击"k"，我希望将其打印在控制台中(不附加在TextArea上)
Fo example: If i click 'k' on keyboard in the TextArea i would like it to be printed in console (not appended to TextArea)
答
朋友，请尝试以下操作:
Friend, try this:
TextArea textArea = new TextArea();
textArea.addEventFilter(KeyEvent.KEY_TYPED, e -> {
if (e.getCharacter().equals("k")) {
e.consume();
}
});
或:
TextArea textArea = new TextArea();
textArea.setOnKeyTyped(e -> {
if (e.getCharacter().equals("k")) {
e.consume();
}
});
