如何关闭和图标化JavaFx阶段

在我的Java Fx应用程序中，我创建了两个阶段 . 第一阶段是主控制器类中的默认值 HomeController . 第二个 AddNewEmailController 是通过调用 AddNewEmailController 类中的方法 showNewComposeNewEmail() 创建的 .

新阶段被创建得很好，但我尝试调用的方法都没有，比如关闭 AddNewEmailController 阶段，将在 AddNewEmailController 阶段工作 .

如何让方法起作用？

一旦 AddNewEmailController 阶段打开，我也希望 HomeController 阶段无法访问，就像弹出窗口一样 .

我甚至无法将 AddNewEmailController 阶段送到 iconify ？

谢谢大家 .

The HomeController class:

public class HomeController implements Initializable {

// Initializes the controller class.
@Override
public void initialize(URL url, ResourceBundle rb) {
    // TODO
}
@FXML
public void windowClose() {
    Platform.exit();
}

@FXML
public void showNewComposeNewEmail() throws Exception {
    new AddNewEmailController().newnewcomposeNewEmailStage();
}
}

The AddNewEmailController class:

public class AddNewEmailController implements Initializable {

public void setScreenParent(ScreensController screenParent) {
    myController = screenParent;
}

// Initializes the controller class.
@Override
public void initialize(URL url, ResourceBundle rb) {
    // TODO
}

public Stage newComposeNewEmail;

public void newnewcomposeNewEmailStage() throws IOException {
    newComposeNewEmail = new Stage();
    newComposeNewEmail.initStyle(StageStyle.UNDECORATED);
    newComposeNewEmail.initStyle(StageStyle.TRANSPARENT);

    Parent newComposeNewEmailRoot = FXMLLoader.load(getClass().getResource("/wakiliproject/Forms/AddNew/NewEmail/NewEmail.fxml"));

    StageDraggable.stageDraggable(newComposeNewEmailRoot, newComposeNewEmail);

    Scene newComposeNewEmailScene = new Scene(newComposeNewEmailRoot, 590, 670);

    newComposeNewEmail.setScene(newComposeNewEmailScene);
    newComposeNewEmail.show();
}

@FXML
private void newComposeNewEmailClose() {
    newComposeNewEmail.close();
}

@FXML
private void newComposeNewEmailIconify() {
    newComposeNewEmail.setIconified(true);
}
}

UPDATE:
