gluon SceneBuilder ToggleButtonGroup不包含getSelectedToggle（）方法

Question

我正在尝试在ToggleButton内创建ToggleGroup，但是场景构建器中提供的ToggleButtonGroup类不包含getSelectedToggle()方法，这将允许我操纵选定的切换状态。但是，这个方法包含在ToggleGroup类中，但不幸的是，这个类在scenebuilder中不存在。

即使ToggleGroup类已启用，也很难，因为它不会扩展javafx.scene.Node ...

我有什么方法可以将getSelectedToggle()方法与类ToggleButtonGroup一起使用？如果不是我有什么方法可以通过这个？

提前感谢...

当我尝试使用ToggleGroup时，这是我的代码：

<Pane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="799.9999000000025" prefWidth="1280.0" xmlns="http://javafx.com/javafx/8.0.141" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.medicalManagement.LoginScreen.LoginScreenController">
  <children>
    <Pane prefHeight="800.0" prefWidth="640.0" />
    <Pane layoutX="641.0" layoutY="34.0" prefHeight="800.0" prefWidth="640.0">
      <children>
        <Label layoutX="18.0" layoutY="168.0" prefHeight="23.0" prefWidth="114.0" text="Username">
          <font>
            <Font size="14.0" fx:id="x1" />
          </font>
        </Label>
        <TextField fx:id="userName" layoutX="17.0" layoutY="213.0" prefHeight="25.0" prefWidth="171.0" />
        <Label font="$x1" layoutX="264.0" layoutY="168.0" prefHeight="25.0" prefWidth="84.0" text="Password" />
        <Button fx:id="login" layoutX="19.0" layoutY="372.0" mnemonicParsing="false" onAction="" prefHeight="32.0" prefWidth="171.0" text="Log In" />
        <Separator layoutY="129.0" orientation="VERTICAL" prefHeight="425.0" prefWidth="0.0" />
            <PasswordField id="passWord" fx:id="passWord" layoutX="238.0" layoutY="211.0" prefWidth="171.0" />
            <Label fx:id="dbStatus" layoutX="501.0" layoutY="756.0" prefHeight="18.0" prefWidth="120.0" />
          <ToggleGroup fx:id="userToggleGroup" toggles="adminToggle, nurseToggle">
              <RadioButton fx:id="adminToggle" layoutX="37.0" layoutY="290.0" mnemonicParsing="false" text="Admin" />
              <RadioButton fx:id="nurseToggle" layoutX="206.0" layoutY="290.0" mnemonicParsing="false" text="Nurse" />
          </ToggleGroup>
      </children>
    </Pane>
  </children>
</Pane>

这是controller类代码：

  @FXML
  private ToggleGroup userToggleGroup;

  private ToggleButton adminToggle;
  @FXML
  private ToggleButton nurseToggle;
  @FXML
  private Label dbStatus;


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


            if (this.loginModel.isDbConnected()){
                this.dbStatus.setText("connected to database");
            }else {
                this.dbStatus.setText("database not connected");
            }

            this.adminToggle.setUserData("Admin");
            this.nurseToggle.setUserData("Nurse");
           this.adminToggle.setToggleGroup(userToggleGroup);
            this.nurseToggle.setToggleGroup(userToggleGroup);


    }

    public  void login(){
        try{
            if (this.loginModel.isLogin(this.userName.getText(), this.passWord.getText(),this.userToggleGroup.getSelectedToggle().getUserData().toString())){
                Stage stage = (Stage)this.login.getScene().getWindow();
                stage.close();
                switch (this.userToggleGroup.getSelectedToggle().getUserData().toString()){
                    case "Admin":
                        adminLogin();
                        break;
                    case "Nurse":
                        nurseLogin();
                        break;
                }
            }else{
                System.out.println(this.userName.getText());

                System.out.println(this.userToggleGroup.getSelectedToggle().getUserData().toString());
            }
        }catch (Exception e ){
            e.printStackTrace();
            System.out.println(this.userName.getText());
            System.out.println(this.passWord.getText());
            System.out.println(this.userToggleGroup.getSelectedToggle().getUserData().toString());
        }
    }

    private void nurseLogin() {
    }

    public void adminLogin(){

    }

    public static void main(String[] args) {

    }
