Question

我希望单击链接时调整窗口大小。当用户单击“忘记密码”超链接时，窗口应缩小。但是我无法改变窗口大小。我一直在尝试用另一个阶段设置大小，但是它不起作用。

我尝试在其控制器的构造函数中设置阶段，但这也不起作用。

公共类Main扩展Application { 私人ConnectToDb db;

@Override
public void start(Stage primaryStage) throws IOException {
    db = new ConnectToDb();
    try {
        FXMLLoader loader = new FXMLLoader();
        loader.setLocation(getClass().getResource("/MainLayout.fxml"));
        loader.setController(new MainController());

        primaryStage.setTitle("Ameenazon");
        primaryStage.setWidth(800);
        primaryStage.setHeight(800);

        Scene scene = new Scene(loader.load());
        scene.getStylesheets().add("/StoreHomePageCSS.css");
     //   primaryStage.setScene(new Scene(loader.load()));
        primaryStage.setScene(scene);
        primaryStage.show();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
public static void main(String[] args) {
    launch(args);
}
}

登录控制器

public class LoginController {
    @FXML
   private Hyperlink forgotPasswordHyperlink = new Hyperlink();
   private Stage stage = new Stage();

public LoginController(MainController mainController) {
    this.mainController = mainController;
}
private void initialize() {
    forgotPasswordHyperlink.setOnAction(e ->{
        try{
            FXMLLoader loader = new FXMLLoader(getClass().getResource("/ForgotPasswordLayout.fxml"));
            loader.setController(new ForgotPasswordController(mainController));

            stage.setWidth(300);
            stage.setHeight(300);
            mainController.getContentPane().getChildren().clear();
            mainController.getContentPane().getChildren().add(loader.load());
        } catch (IOException d){
            d.printStackTrace();
        }
    });
    }

忘记密码控制器

public class ForgotPasswordController {    
    private MainController mainController;

    public ForgotPasswordController(MainController mainController){
        this.mainController = mainController;
}

因此，理想情况下，当用户单击丢失的密码超链接时，窗口将调整为首选尺寸（300x300）。现在，它的默认值为800 x 800（在主类中设置）。谢谢你的帮助。
