我如何遍歷多個屏幕javafx？

Question

真的，我需要知道我可以從登錄屏幕去MAINMENU屏幕的JavaFX

public class LoginUIController implements Initializable { 


    @FXML 
    PasswordField pasf = new PasswordField(); 

    @FXML 
    Button bt1 = new Button(); 
    @FXML 
    Button bt2 = new Button(); 
    @FXML 
    Button bt3 = new Button(); 
    @FXML 
    Button bt4 = new Button(); 
    @FXML 
    Button bt5 = new Button(); 
    @FXML 
    Button bt6 = new Button(); 
    @FXML 
    Button bt7 = new Button(); 
    @FXML 
    Button bt8 = new Button(); 
    @FXML 
    Button bt9 = new Button(); 
    @FXML 
    Button bt0 = new Button(); 
    @FXML 
    Button btLogin = new Button(); 
    @FXML 
    Button btDelete = new Button(); 
    @FXML 
    Button btClose = new Button(); 
    @FXML 
    Label timeLb = new Label(); 



    @Override 
    public void initialize(URL location, ResourceBundle resources) { 

     pasf.setEditable(false); 
     setActions(); 
     setFocus(); 

    } 


    private void setActions(){ 

     bt0.setOnMouseClicked(e->{pasf.appendText("0");}); 
     bt1.setOnMouseClicked(e->{pasf.appendText("1");}); 
     bt2.setOnMouseClicked(e->{pasf.appendText("2");}); 
     bt3.setOnMouseClicked(e->{pasf.appendText("3");}); 
     bt4.setOnMouseClicked(e->{pasf.appendText("4");}); 
     bt5.setOnMouseClicked(e->{pasf.appendText("5");}); 
     bt6.setOnMouseClicked(e->{pasf.appendText("6");}); 
     bt7.setOnMouseClicked(e->{pasf.appendText("7");}); 
     bt8.setOnMouseClicked(e->{pasf.appendText("8");}); 
     bt9.setOnMouseClicked(e->{pasf.appendText("9");}); 
     btDelete.setOnMouseClicked(e->{pasf.clear();}); 
     btClose.setOnMouseClicked(e->{ 

     Stage stage = (Stage) btClose.getScene().getWindow(); 
     stage.close(); 

     }); 
     btLogin.setOnMouseClicked((MouseEvent e)->{ 

     }); 
    } 

    private void setFocus(){ 

     pasf.requestFocus(); 
     bt0.requestFocus(); 
     bt1.requestFocus(); 
     bt2.requestFocus(); 
     bt3.requestFocus(); 
     bt4.requestFocus(); 
     bt5.requestFocus(); 
     bt6.requestFocus(); 
     bt7.requestFocus(); 
     bt8.requestFocus(); 
     bt9.requestFocus(); 
     btClose.requestFocus(); 
     btDelete.requestFocus(); 
     btLogin.requestFocus(); 
    } 
}

    } 

    /** 
    * @param args the command line arguments

Answer 1

在這裏，你有兩個選擇：

1. 爲登錄創建兩個階段，爲主要部分創建一個階段。登錄成功後，隱藏登錄階段並顯示主要階段。
2. 使用其中的登錄內容和主要內容創建一個階段。登錄成功後隱藏登錄內容並顯示主內容。
