Question

我有多屏幕的javafx应用程序，并且每次都在旧屏幕上覆盖新屏幕但是对于一个案例我需要2个屏幕如图所示：

但是当点击事件viewresult窗口时，新屏幕应该添加到另一个窗口。

喜欢：我有2个窗口窗格分析窗口和查看结果窗口窗格如果我在查看结果窗口上执行任何单击事件，则分析窗口应更改为新窗口。示例代码共享如下：

ScreensController

public class ScreensController  extends StackPane {
    //Holds the screens to be displayed

    private HashMap<String, Node> screens = new HashMap<>();

    public ScreensController() {
        super();
    }

    //Add the screen to the collection
    public void addScreen(String name, Node screen) {
        System.out.println(" adding ");
        screens.put(name, screen);
        System.out.println("checking :"+screens.get(name));
    }

    //Returns the Node with the appropriate name
    public Node getScreen(String name) {
        return screens.get(name);
    }

    //Loads the fxml file, add the screen to the screens collection and
    //finally injects the screenPane to the controller.
    public boolean loadScreen(String name, String resource) {
        System.out.println("Name :"+name +" and Resources is :"+resource);
        try {

            FXMLLoader myLoader = new FXMLLoader(getClass().getResource(resource));
            //System.out.println("2");
            Parent loadScreen = (Parent) myLoader.load();
           // System.out.println("3");
            ControlledScreen myScreenControler = ((ControlledScreen) myLoader.getController());
           // System.out.println("4");
            myScreenControler.setScreenParent(this);
           // System.out.println("5");
            addScreen(name, loadScreen);
           // System.out.println("6");
            return true;
        } catch (Exception e) {
            System.out.println(e.toString());
            return false;
        }
    }

    //This method tries to displayed the screen with a predefined name.
    //First it makes sure the screen has been already loaded.  Then if there is more than
    //one screen the new screen is been added second, and then the current screen is removed.
    // If there isn't any screen being displayed, the new screen is just added to the root.
    public boolean setScreen(final String name) {
