スレッド「JavaFX Application Thread」の例外java.lang.IllegalArgumentException：引数タイプの不一致

Question

私は数独ゲームを作らなければなりません。私はコードを試したときに私は自分で修復できない問題を発見しました。私は私は本当に感謝するでしょう私の問題か、いくつかのアドバイスを解決するために、あなたが任意のアイデアを持っているSceneBuilder.If使用しています
私のコード：
FXMLDocumentController

public class FXMLDocumentController implements Initializable { 

@FXML 
private GridPane grid; 
public TextField[][] field= new TextField[9][9]; 
public class getXY{ 
    private TextField temp; 
    private int a; 
    int x,y; 
    public int getNodeByRowColumnIndex(final int row,final int column,GridPane gridPane) { 
    Node result = null; 
    ObservableList<Node> childrens = gridPane.getChildren(); 
    for(Node node : childrens) { 
     if(gridPane.getRowIndex(node) == row && gridPane.getColumnIndex(node) == column) { 
      temp = (TextField) node; 
      a=Integer.parseInt(temp.getText()); 
      break; 
     } 
    } 
    return a; 
} 
} 
@FXML 
private void handleButtonAction(ActionEvent event) { 
    getXY a = new getXY(); 
    for (int i=0; i<9;i++) 
     for (int j=0; j<9;j++){ 

    //int temp=a.getNodeByRowColumnIndex(i, j, grid); 
    System.out.println("1"); 

     } 

     } 




@Override 
public void initialize(URL url, ResourceBundle rb) { 
    for (int i=0; i<9;i++) 
     for (int j=0; j<9;j++){ 
      //field[i][j].setText("0"); 
      TextField ffield = new TextField("0"); 
      grid.add(ffield,i,j); 
     }  
} } 

FXMLDocument.fxml

    </rowConstraints> 
    </GridPane> 
    </children> 
</AnchorPane> 

そして、結果は

Answer 1

ハンドラーメソッドはonKeyReleasedにリンクされています。 GridPaneためdler：

<GridPane fx:id="grid" ... onKeyReleased="#handleButtonAction" ... > 

onKeyReleasedは、パラメータの型がKeyEvent、ないActionEventする必要があります（あなたは非常に紛らわしいhandleButtonAction名付けた）あなたの方法、EventHandler<KeyEvent>を期待しているので：

@FXML 
private void handleButtonAction(KeyEvent event) { 
    // ... 
}
