我有一个默认太宽的手风琴。一段时间以来，我一直试图找到一种方法来设置手风琴的宽度，但没有成功。我想让它小于默认宽度。有没有办法让这成为可能？我错过了什么吗？

这是我的代码

 public final class StudentInfo
{
   private Accordion accordion;
   private Pane mView;
   private TextField[] mStudenInfo;
   private Label[] mLabelInfo;
   private HBox[] mStudentContainer;

   private HBox mHBox;
   private VBox mLeft;
   private VBox mRight;

   private Stage primaryStage;


   private VBox mImageBox;


   private Image mImage;

   StudentInfo()

      mImageBox = new VBox();

      mI = 0;

      mStudenInfo = new TextField[]{new TextField(), new TextField(),

      mLabelInfo = new Label[]{new Label("First Name"), new Label("Last Name"),
                               new Label("Preffered Name"),new Label("Email"),
                               new Label("Phone"), new Label("City"),

      mI = 0;
   }

   public Pane getView()
   {
      return mView;
   }

   public void setActions()
   {
      mChangeImage.setOnAction(new EventHandler<ActionEvent>()
                               {
                                  private FileChooserBuilder fcb;
                                  private File selectedFile;
                                  @Override
                                     public void handle(ActionEvent Event)
                                  {
                                     String currentDir =
                                        System.getProperty("user.dir") + File.separator;
                                     StringBuilder sb = null;
                                     fcb = FileChooserBuilder.create();

                                     FileChooser fc =
                                        fcb.title("Open Dialog").initialDirectory(new File(currentDir))
                                        .build();
                                     selectedFile = fc.showOpenDialog(Main.mStage);

                                     if (selectedFile != null)
                                     {
                                        System.out.println("you selected " +   

selectedFile.getName());
                                     }
                                  }
                               });
   }

   public static void addToList(String pName)
   {
      mList[0].getItems().add("any Name here");//pName);

   }
}

我曾尝试使用手风琴.setMaxWidth，但它不会改变手风琴的宽度。

我发现了我的问题。手风琴的大小超出了手风琴列表视图的大小。通过在列表视图上设置最大宽度，它将更改手风琴选项卡的大小。

例如：

mList[0].setMaxWidth(10);
