管理JavaFX菜单栏的运行时行为

我有一个BorderPane，我在其上放置了一个MenuBar。在BorderPane的中心，根据所选的MenuItem，我显示不同的AnchorPanes。到现在为止还挺好。管理JavaFX菜单栏的运行时行为

现在，我如何确保菜单更改行为以响应在子AnchorPane中选择的项目？因此，例如，如果用户选择“编辑”，会出现根据当前亮显的项目是否是一个用户账号，文件等

到目前为止，我做东西沿着这些路线不同的动作：

该BorderPane控制器：

public class MenuTest implements Initializable{ 
@FXML 
private BorderPane borderPaneMain; 
@FXML 
private AnchorPane anchorPaneMain; 
@FXML 
private Menu menuEdit; 
@FXML 
private MenuItem itemEdit; 
static String menuMode; 
static String entityName; 
public MenuTest(){ 
    menuMode =""; 
    entityName = ""; 
} 
@Override 
public void initialize(URL arg0, ResourceBundle arg1) { 
    AnchorPane anchor; 
    try { 
     anchor = (AnchorPane) new FXMLLoader().load(getClass().getResource("views/MainView.fxml")); 
     borderPaneMain.setCenter(anchor); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
} 
protected static void setMenuMode(String menuMd, String entityNm){ 
    entityName = entityNm; 
    menuMode = menuMd; 
} 
@FXML 
private void onEditClick(){ 
    if(entityName.equals(AnchorTest.FILE)){ 
     //Launches correct edit view 
     new FXMLLoader().load(getClass().getResource("views/EditFile.fxml")); 
     //Passes the name of the entity so that the controller can retrieve its data 
     FileEditController.setFile(entityName); 
    }else if(entityName.equals(AnchorTest.PERSON)){ 
     new FXMLLoader().load(getClass().getResource("views/EditPerson.fxml")); 
     PersonEditController.setFile(entityName); 
    }     
} 
}

孩子AnchorPane控制器：

public class AnchorTest implements Initializable{ 
public static final String PERSON = "PERSON"; 
public static final String FILE = "FILE"; 
ObservableList<String> peopleList; 
ObservableList<String> fileList; 
@FXML 
private ListView<String> listPeople; 
@FXML 
private ListView<String> listFiles; 
@Override 
public void initialize(URL location, ResourceBundle resources) { 
    peopleList = FXCollections.observableArrayList("Frank","Matin","Anne"); 
    fileList = FXCollections.observableArrayList("hello.txt","holiday.jpg","cv.doc"); 
    listPeople.setItems(peopleList); 
    listFiles.setItems(fileList); 
} 
@FXML 
private void personSelected(){ 
    MenuTest.setMenuMode(this.PERSON, listPeople.getSelectionModel().getSelectedItem()); 
} 
@FXML 
private void fileSelected(){ 
    MenuTest.setMenuMode(this.FILE, listFiles.getSelectionModel().getSelectedItem()); 
} 
}
