JavaFX - 新的ImageView和set方法

Question

我必须用新的Object初始化GridPane - ＆gt; ImageView的。使用scenebuilder，我将属性“onMouseClicked”的方法“handleOnMouseClicked”。但是，当我点击重启游戏时，我删除了我板上的所有ImageView，并且我创建了没有handleOnMouseClicked方法的新ImageView对象..我该怎么办？

@FXML
   private void restartGame(ActionEvent event)throws Exception{
      myGrid.getChildren().removeIf(ImageView.class::isInstance);
      EventHandler<? extends Event> onClick = imgView.getOnMouseClicked(); 
      for (int i = 0; i < 8; i++){ //Per righe
         for (int j = 0; j < 8; j++){ // Per colonne
            myGrid.add(new ImageView().setOnMouseClicked(onClick), i, j); //String with error
         }
      }
      myGrid.add(new ImageView(black), 3, 3); // 4 pieces in the center of my grid
      myGrid.add(new ImageView(black), 4, 4);
      myGrid.add(new ImageView(white), 3, 4);
      myGrid.add(new ImageView(white), 4, 3);
      rd_p1_white.setSelected(false); // radiobuttons
      rd_p2_white.setSelected(false);
      rd_p1_black.setSelected(false);
      rd_p2_black.setSelected(false);
   }
