JavaFx Olay argümanı türü uyuşmazlığı

Question

JavaFx'i ilk defa kullanıyorum ve olaylarla ilgili bir sorunla karşılaştım. Ben SceneBuilder ile bir form inşa ve ben .fxml ve denetleyici bir olay eklemek ama her zaman birlikte dönmek oluyor:

Exception in thread "JavaFX Application Thread" java.lang.IllegalArgumentException: argument type mismatch 

FirstScene.fxml:

<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" styleClass="background" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="examlog.gui.FirstSceneController"> 
    <stylesheets> 
     <URL value="@dark_style.css" /> 
    </stylesheets> 
    <children> 
     <TableView fx:id="firstScene_tableView" layoutX="30.0" layoutY="42.0" prefHeight="287.0" prefWidth="600.0" AnchorPane.bottomAnchor="71.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="42.0"> 
     <columns> 
      <TableColumn text="C1" /> 
      <TableColumn prefWidth="70.0" text="C2" /> 
     </columns> 
     </TableView> 
     <Label layoutX="14.0" layoutY="14.0" text="Létrehozott munkafolyamatok:" /> 
     <Button fx:id="firstScene_newbutton" layoutX="522.0" layoutY="353.0" mnemonicParsing="false" onMouseClicked="#newButtonClick" text="ÚJ" /> 
    </children> 
</AnchorPane> 

FirstSceneController.java:

public class FirstSceneController implements Initializable { 

    @FXML 
    private Button firstScene_newbutton; 
    @FXML 
    private TableView firstScene_tableView; 

    /** 
    * Initializes the controller class. 
    */ 
    @Override 
    public void initialize(URL url, ResourceBundle rb) { 

    } 

@FXML 
    private void newButtonClick(ActionEvent event) { 
     System.out.println("You clicked me!"); 

    } 



} 

JavaFxApplication.java:

public class JavaFXApplication extends Application { 

    private Stage stage; 

    @Override 
    public void start(Stage primaryStage) { 
     this.stage = primaryStage; 
     try { 
      FirstScene(); 
      primaryStage.setTitle("FXML is Simple"); 
      primaryStage.show(); 
     } catch (IOException ex) { 
      Logger.getLogger(JavaFXApplication.class.getName()).log(Level.SEVERE, null, ex); 
     } 

    } 

    public void FirstScene() throws IOException { 
     AnchorPane page = (AnchorPane) FXMLLoader.load(JavaFXApplication.class.getResource("FirstScene.fxml")); 
     Scene scene = new Scene(page); 
     stage.setScene(scene); 

    } 

}

Yardıma gerçekten takdir ediyorum.

Answer 1

onAction="#newButtonClick" kullanın, onMouseClicked.

Answer 2

deneyin KeyEvent yerine

@FXML 
private void newButtonClick(KeyEvent event) { ...}
