fxmlファイルとフローライブラリを使用してコントローラのパラメータを取得する方法は？

設定がインスタンス化され、MainControllerで初期化されているコンストラクタのパラメータ "Settings"オブジェクトでMoviesSettingsControllerを呼び出すにはどうすればよいですか？ SideMenuControllerでSettingsを渡し、次にMoviesSettingsControllerで設定を渡す必要がありますか？私はこれで失われた小さなビットです。fxmlファイルとフローライブラリを使用してコントローラのパラメータを取得する方法は？

MainApp.java：

public void start(Stage stage) throws Exception { 
    Flow flow = new Flow(MainController.class); 
    DefaultFlowContainer container = new DefaultFlowContainer(); 
    flowContext = new ViewFlowContext(); 
    flowContext.register("Stage", stage); 
    flow.createHandler(flowContext).start(container); 

    JFXDecorator decorator = new JFXDecorator(stage, container.getView()); 
    decorator.setCustomMaximize(true); 
    Scene scene = new Scene(decorator, 770, 690); 
    scene.getStylesheets().add(MainMaxiFilm.class.getResource("/resources/css/jfoenix-main-demo.css").toExternalForm()); 
    stage.setWidth(770); 
    stage.setHeight(690); 
    stage.setResizable(false); 
    stage.setScene(scene); 
    stage.show(); 
}

MainController.java：

public class MainController implements Initializable{ 

    @FXMLViewFlowContext 
    private ViewFlowContext context;

       if (mainDrawer. isShown() || mainDrawer.isShowing()) {

      }); 

      // create the inner flow and content 
      context = new ViewFlowContext(); 
      // set the default controller 
      Flow innerFlow = new Flow(HomeController.class); 

      flowHandler = innerFlow.createHandler(context); 
      context.register("ContentFlowHandler", flowHandler); 
      context.register("ContentFlow", innerFlow); 
      mainDrawer.setContent(flowHandler.start());

      // side controller will add links to the content flow 
      Flow sideMenuFlow = new Flow(SideMenuController.class); 
      sideMenuFlowHandler = sideMenuFlow.createHandler(context);

      Logger.getLogger(MainController.class.getName()).log(Level.SEVERE, null, ex); 
     } 
    }

あなたは一瞬で

後にすべての私のファイルを見つけるだろう、私はこのエラーを取得します

SideMenuController.java：

@FXMLController(value = "/resources/fxml/SideMenu.fxml", title = "Material Design Example") 
public class SideMenuController { 


    @FXML 
    private StackPane root; 

    @FXML 
    private VBox listViewDrawer; 

    @FXML 
    private ImageView imageTopDrawer; 

    @FXML 
    private JFXListView<?> sideList; 

    @FXML 
    private Label home; 

    @FXML 
    private JFXListView<?> subList; 

    @FXML 
    private Label musics; 

    @FXML 
    private Label movies; 

    @FXML 
    private Label series; 

    @FXML 
    private Label help; 

    @FXML 
    private Label exit; 

    @FXMLViewFlowContext 
    private ViewFlowContext context; 

    @PostConstruct 
    public void init() throws FlowException, VetoException { 
     sideList.propagateMouseEventsToParent(); 
     System.out.println(context); 
     FlowHandler contentFlowHandler = (FlowHandler) context.getRegisteredObject("ContentFlowHandler"); 
     Flow contentFlow = (Flow) context.getRegisteredObject("ContentFlow"); 
     System.out.println(subList.getItems().get(0)); 
     bindNodeToController(home, HomeController.class, contentFlow, contentFlowHandler); 
     bindNodeToController(musics, MusicsSettingsController.class, contentFlow, contentFlowHandler); 
     bindNodeToController(movies, MoviesSettingsController.class, contentFlow, contentFlowHandler); 
     bindNodeToController(series, SeriesSettingsController.class, contentFlow, contentFlowHandler); 
     bindNodeToController(help, HelpController.class, contentFlow, contentFlowHandler); 
    } 

    private void bindNodeToController(Node node, Class<?> controllerClass, Flow flow, FlowHandler flowHandler) { 
     flow.withGlobalLink(node.getId(), controllerClass); 
     node.setOnMouseClicked((e) -> { 
      try {    
       flowHandler.handle(node.getId());    
      } catch (Exception e1) { 
       e1.printStackTrace(); 
      } 
     }); 
    } 
}

そしてMoviesSettingsControler.java：私は、コントローラで設定オブジェクトをしたい

@FXMLController(value = "/resources/fxml/MoviesSettings.fxml" , title = "Material Design Example") 
public class MoviesSettingsController{ 

    @FXML 
    private GridPane gridSettingsMovies; 

    @FXML 
    private Label labelSettingsMovies; 

    @FXML 
    private Label labelFilesNameSettingsMovies; 

    @FXML 
    private JFXButton buttonCancelMoviesSettings; 

    @FXML 
    private JFXButton buttonOKMoviesSettings; 

    @FXML 
    private GridPane gridFilesName; 

    @FXML 
    private ToggleGroup groupFilesName; 

    @FXML 
    private JFXRadioButton radioButtonFiles5; 

    @FXML 
    private JFXRadioButton radioButtonFiles6; 

    @FXML 
    private JFXRadioButton radioButtonFiles3; 

    @FXML 
    private JFXRadioButton radioButtonFiles2; 

    @FXML 
    private JFXRadioButton radioButtonFiles1; 

    @FXML 
    private JFXRadioButton radioButtonFiles4; 

    private Settings settings = new Settings(); 

    public MoviesSettingsController (Settings pSettings) 
    { 
     this.settings = pSettings; 
    } 

    public Settings getSettings() { 
     return settings; 
    } 

    public void setSettings(Settings settings) { 
     this.settings = settings; 
    } 

    public void saveChange (int pRb, int pPart) 
    { 
     this.settings.setMovieName(pRb);  
    } 

    @FXML 
    void saveSettingsMovies(ActionEvent event) { 
     System.out.println(groupFilesName.getSelectedToggle()); 
    }

。 問題は、この（と思う）（コードSideMenuController.javaから来る）の周りにある：

@PostConstruct 
    public void init() throws FlowException, VetoException { 
     sideList.propagateMouseEventsToParent(); 
     System.out.println(context); 
     FlowHandler contentFlowHandler = (FlowHandler) context.getRegisteredObject("ContentFlowHandler"); 
     Flow contentFlow = (Flow) context.getRegisteredObject("ContentFlow"); 
     System.out.println(subList.getItems().get(0)); 
     bindNodeToController(home, HomeController.class, contentFlow, contentFlowHandler); 
     bindNodeToController(musics, MusicsSettingsController.class, contentFlow, contentFlowHandler); 
     bindNodeToController(movies, MoviesSettingsController.class, contentFlow, contentFlowHandler); 
     bindNodeToController(series, SeriesSettingsController.class, contentFlow, contentFlowHandler); 
     bindNodeToController(help, HelpController.class, contentFlow, contentFlowHandler); 
    } 

    private void bindNodeToController(Node node, Class<?> controllerClass, Flow flow, FlowHandler flowHandler) { 
     flow.withGlobalLink(node.getId(), controllerClass); 
     node.setOnMouseClicked((e) -> { 
      try {    
       flowHandler.handle(node.getId());    
      } catch (Exception e1) { 
       e1.printStackTrace(); 
      } 
     }); 
    }

はどうもありがとうございました:)

[OK]を、私は働く何かを見つけました。より良い方法が見えたら、教えてください:)。

私はこのようなコンテキストを作成したが、メインコントローラで：

ViewFlowContext context = new ViewFlowContext();

私は、フローオブジェクトを介して他のコンポーネントに渡したいすべてのパラメータとの内容でそれを満たしました。私は次のように記入しました：

@FXML 
private JFXDrawer mainDrawer; 
private FlowHandler flowHandler; 
private FlowHandler sideMenuFlowHandler; 

context.register("ContentFlowHandler", flowHandler); 
context.register("Settings", new Settings()); 
context.register("ContentFlow", innerFlow);

私はフローライブラリを使用しています。私は、必要なすべての変数とオブジェクトをコンテキストに渡します。

Flow sideMenuFlow = new Flow(SideMenuController.class); 
sideMenuFlowHandler = sideMenuFlow.createHandler(context); 
mainDrawer.setSidePane(sideMenuFlowHandler.start());

その後、sideMenuControllerに移動します。

そして、このようなcontextからすべてこのようなものを取り戻す：movieSettingsControllerで、私はコンテキストを経由して値を取り戻すと、それはそれだ、終了するには

FlowHandler contentFlowHandler = (FlowHandler) context.getRegisteredObject("ContentFlowHandler"); 
Flow contentFlow = (Flow) context.getRegisteredObject("ContentFlow");

:)

settings = (Settings) context.getRegisteredObject("settings");

最終あなたがコントローラを使用したいときは、コントローラーの注釈@PostConstructを忘れないでください。 例：

@PostConstruct 
public void init() { 
    // TODO Auto-generated method stub 
    settings = (Settings) context.getRegisteredObject("Settings"); 
}

他にも役立つことを願っています。あなたがこの世界全体を発見し始めると、それほど簡単ではありません。
