JavaFX TabPane从外部控制器中选择选项卡

问题描述 投票：0回答：1

我在此有用的帖子（PASSING PARAMETERS JAVAFX FXML）的开头更改了代码之后，我的setTab函数无法正常工作。它被调用，但没有执行应做的操作。

Main.java

public class Main extends Application {

public static void main(String[] args) {
    launch(args);
}
@Override
public void start(Stage primaryStage){
        Controller1 controller1 = new Controller1();
        controller1.showStage();
  }
}

Controller1.java

public class Controller1{

private final Stage thisStage;
private Controller2 controller2 = new Controller2(this);

public Controller1() {
    thisStage = new Stage();

    try {
        FXMLLoader loader = new FXMLLoader(getClass().getResource("Steuerung.fxml"));
        loader.setController(this);
        thisStage.setScene(new Scene(loader.load()));
        thisStage.setTitle("Steuerung");
    }catch (IOException e){
        e.printStackTrace();
     }
}

public void showStage(){ thisStage.show();}

@FXML private void initialize() {
    b_AnzeigeÖffnen.setOnAction(e -> openAnzeige());
    b_Ecke_Eingabe.setOnAction(e -> controller2.setTab(2));
}

private void openAnzeige(){
    Controller2 controller2 = new Controller2(this);
    controller2.showStage();
}

！包装和进口件的车身长度已被删除！

我知道我必须重写最后几个函数，因为它们很容易合而为一。

Steuerung.fxml和Anzeige.fxml太长了。如果您想看到它们，这是完整的GitLab项目。GitLab Project

对不起，德语注释，函数/变量名和/或对象

感谢您的建议！

编辑：语法

Controller1.java

public class Controller1{

private final Stage thisStage;
private Controller2 controller2 = new Controller2(this);

public Controller1() {
thisStage = new Stage();

try {
    FXMLLoader loader = new FXMLLoader(getClass().getResource("Steuerung.fxml"));
    loader.setController(this);
    thisStage.setScene(new Scene(loader.load()));
    thisStage.setTitle("Steuerung");
}catch (IOException e){
    e.printStackTrace();
 }
}

public void showStage(){ thisStage.show();}

@FXML private void initialize() {
    b_AnzeigeÖffnen.setOnAction(e -> openAnzeige());
    b_Ecke.setOnMouseClicked(e -> controller2.setTab(2));
}

private void openAnzeige(){
    Controller2 controller2 = new Controller2(this);
    controller2.showStage();
}

@FXML
private Label b_Ecke;

@FXML
private MenuItem b_AnzeigeÖffnen
}

更好？
