JavaFX处理程序不起作用

Question

我的控制器有问题。当我点击按钮时，没有任何反应。 该方法将起作用：

@FXML
    public void handleNewProject() {
        code.setText("");
        inOutPut.setText("");
    }

它的按钮：

<Button mnemonicParsing="false" onMouseClicked="#handleNewProject" prefHeight="30.0" prefWidth="150.0" text="New" />

MainApp

public class MainApp extends Application {

private Stage primaryStage;
private BorderPane rootLayout;

@Override
public void start(Stage primaryStage) {
    this.primaryStage = primaryStage;
    this.primaryStage.setTitle("MyLittleIDE");

    initRootLayout();

    showDesk();
    showTool();
}

public void initRootLayout() {
    try {
        FXMLLoader loader = new FXMLLoader();
        loader.setLocation(MainApp.class.getResource("view/RootLayout.fxml"));
        rootLayout = (BorderPane) loader.load();

        Scene scene = new Scene(rootLayout);
        primaryStage.setScene(scene);
        primaryStage.show();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public void showDesk() {
    try {
        FXMLLoader loader = new FXMLLoader();
        loader.setLocation(MainApp.class.getResource("view/DeskLayout.fxml"));
        AnchorPane personOverview = (AnchorPane) loader.load();

        rootLayout.setCenter(personOverview);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public void showTool() {
    try {
        FXMLLoader loader = new FXMLLoader();
        loader.setLocation(MainApp.class.getResource("view/ToolLayout.fxml"));
        GridPane tool = (GridPane) loader.load();

        rootLayout.setBottom(tool);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

...

}

ToolLayout

public class ToolLayoutController {
    @FXML
    private TextArea code;
    @FXML
    private TextArea inOutPut;

    @FXML
    public void handleNewProject() {
        code.setText("");
        inOutPut.setText("");
    }
}
