出于某种原因，当我使用setOnMouseEntered / Exited时会发生闪烁效果

有什么想法吗？在删除killThis之前，它不应该等我离开按钮。另外，作为一个注释，按钮不在killThis下，因此不是问题。

button.setOnMouseEntered(new EventHandler<MouseEvent>
           () {
               public void handle(MouseEvent t) 
               {
                   killThis = cardDrawer.drawCard(button.getCardID());
                   layout.getChildren().add(killThis);
               }
            });

            //Exit hover over button
            button.setOnMouseExited(new EventHandler<MouseEvent>
             () {
                 public void handle(MouseEvent t) 
                 {
                    layout.getChildren().remove(killThis);
                 }
             });

这是使用drawCard（）;

加载的内容

public StackPane drawCard(int I)
{
    StackPane cardViewer= new StackPane();

    CardList cards= new CardList();
    ImageView background = new ImageView(new Image(getClass().getResourceAsStream(cards.getCardList()[I].getBackgroundID())));
    ImageView frame = new ImageView(new Image(getClass().getResourceAsStream(cards.getCardList()[I].getFrameID())));
    ImageView nameFrame = new ImageView(new Image(getClass().getResourceAsStream(cards.getCardList()[I].getNameID())));
    ImageView valueFrame = new ImageView(new Image(getClass().getResourceAsStream(cards.getCardList()[I].getValueID())));
    Text textName = new Text(cards.getCardList()[I].getName());
    Text textMana = new Text(""+ cards.getCardList()[I].getManaCost());
    textName.setFont(Font.font("Verdana",FontWeight.BOLD, 20));
    ImageView attackBoarder = new ImageView(new Image(getClass().getResourceAsStream(cards.getCardList()[I].getAttackBoarderID())));
    ImageView healthBoarder = new ImageView(new Image(getClass().getResourceAsStream(cards.getCardList()[I].getHealthBoarderID())));
    Text textHealth = new Text("" + cards.getCardList()[I].getActHealth());
    textHealth.setFill(Color.RED);
    Text textAttack = new Text("" + cards.getCardList()[I].getActAttack());

    textName.setTranslateY(-225);
    frame.setTranslateY(-50);
    nameFrame.setTranslateY(-225);
    valueFrame.setTranslateX(-175);
    valueFrame.setTranslateY(-200);
    textMana.setTranslateX(-175);
    textMana.setTranslateY(-200);
    healthBoarder.setTranslateX(185);
    healthBoarder.setTranslateY(125);
    attackBoarder.setTranslateX(-185);
    attackBoarder.setTranslateY(125);
    textHealth.setTranslateX(185);
    textHealth.setTranslateY(125);
    textAttack.setTranslateX(-185);
    textAttack.setTranslateY(125);

    cardViewer.getChildren().add(background);
    cardViewer.getChildren().add(frame);
    cardViewer.getChildren().add(nameFrame);
    cardViewer.getChildren().add(textName);
    cardViewer.getChildren().add(valueFrame);
    cardViewer.getChildren().add(attackBoarder);
    cardViewer.getChildren().add(healthBoarder);
    cardViewer.getChildren().add(textHealth);
    cardViewer.getChildren().add(textAttack);
    cardViewer.getChildren().add(textMana);

    return cardViewer;
}

编辑：所以我决定将killThis移到右边框，问题解决了，但是节点并没有妨碍按钮。有什么想法吗？

对于最小，完整和可验证的部分也很抱歉，只需要输入很多代码，我认为这是一个快速修复。：P

javafx为什么这个事件处理程序会闪烁？
