Question

I am writing an application with 2 different BorderPanes, BorderPane A and BorderPane B. The application has 2 menuitems, such that, when clicked it HAS to show BorderPane A or BorderPane B.

这是应用程序类, 它有我要使用的阶段

public class SampleApp extends Application {
private Stage primaryStage;

public static void main(final String[] args) {
    launch(args);
时 时   
@Override
public void start(final Stage stage)
        throws Exception {
    final AnnotationConfigApplicationContext context = new  AnnotationConfigApplicationContext(SampleAppFactory.class);
    final SpringFxmlLoader loader = new SpringFxmlLoader(context);      
    final Parent root = (Parent) loader.load("Main.fxml", Main.class);
    final Scene scene = new Scene(root, 600, 480, Color.ALICEBLUE);
    this.primaryStage = stage;
    scene.getStylesheets().add("fxmlapp.css");
    stage.setScene(scene);
    stage.show();
}
}

在选择菜单时, 主雅瓦级有两个边框, 我想在应用程序上显示边板。

Does someone knows how to show the Borderpane(set the Scene on Stage) from this method(showBorderPane)? I d like to retrieve the Stage and set the scene with de borderpane:

public class Main extends BorderPane implements Initializable {

@FXML
private Verbinding verbindingContent; // BORDERPANE A
@FXML
private Beheer beheerContent;// BORDERPANE A
@FXML
private MenuBar menuContent;

@Override
public void initialize(final URL url, final ResourceBundle rb) {
    System.out.println(url);
    menuContent.setFocusTraversable(true);
}

@FXML
private void showBorderPane(final ActionEvent event) {
    final MenuItem menuItem = (MenuItem) event.getSource();
}


@FXML
private void handleCloseAction(final ActionEvent event) {
    System.exit(0);
}

                    <MenuItem text="Verbinding maken" onAction="#handleVerbindingAction"/>
                    <SeparatorMenuItem />
                    <MenuItem text="Afsluiten"  onAction="#handleCloseAction"/>
                </items>
            </Menu>

            <Menu text="TAB">
                <items>
                    <MenuItem text="Script toevoegen" onAction="#handleAboutAction"/>
                    <SeparatorMenuItem />
                    <MenuItem text="Script draaien" />                      
                </items>
            </Menu>
            <Menu text="About" onAction="#handleAboutAction">
                <items>
                    <MenuItem text="Op basis van wizard" />
                </items>
            </Menu>
        </menus>
    </MenuBar>
</top> 
<center>   <Label text="Add New Dock of Home" />

</center>

I ve seen it is possible to do this from the start method of the application. But I d like to implement it in the Main.java because of structure and I am using mainly FXML to declare the GUI.

当 FXMLLoader 装入“ 主程序” 文件时, 将创建一个新的 BrainPane (定义在 Main. fxml 中) 。装载器还将创建/ 初始化其控制器类, 这是另一个由BrontPane 衍生的类别。因此有两种不同的 BrontPanes 实例。您的设计与一般方法略有不同, 但是, 为了实现您的目标, 我建议将一个容器添加到 FXML 文件的中心 :

<center>
    <StackPane fx:id="pane">
        <children>
              <Label text="Add New Dock of Home" />
        </children>
    </StackPane>
</center>

You can change the StackPane with any pane/layout you want. Next make a link to it in the controller class:

@FXML
private StackPane pane;

您的“ 强” 应 < / 强” 删除“ 扩展边界Pane ”, 因为它已经没有意义了。最后,

@FXML
private void showBorderPane(final ActionEvent event) {
    final MenuItem menuItem = (MenuItem) event.getSource();
    pane.getChildren().clear(); // Clear old content.
    switch (menuItem.getText()) {
        case "Borderpane A":
            pane.getChildren().add(borderPaneA);
            break;
        case "Borderpane B":
            pane.getChildren().add(borderPaneB);
            break;
       default:
            pane.getChildren().add(new Label("Add New Dock of Home"));
    }
}
