c#流程布局标签卡住了

Question

我有一个带有两个自定义面板的表单,我正在为它们添加一些标签,最后我希望它们从右向左滚动,但它们只是在相同的位置.有我的截图 有两个面板和4个标签,它们只是停留在那里......这是我的表格中的代码:

  private MyPanel topPanel;  // the red bar
  private MyPanel botPanel;  // the white bar

        public SmsBar()
    {
        InitializeComponent();

        this.Width = 500000;

        this.Location = new Point(x, y);

        topPanel = new MyPanel(System.Drawing.Color.White, System.Drawing.Color.Red, (new Font("Tahoma", 10, FontStyle.Bold)));
        botPanel = new MyPanel(System.Drawing.Color.Black, System.Drawing.Color.White, (new Font("Tohama", 10, FontStyle.Regular)));

        msgPanel.Controls.Add(topPanel);
        adPanel.Controls.Add(botPanel);
        botPanel.addMsg(new MsgForDisplay(0, AppData.getInstance().getAdMsg()));
        botPanel.addMsg(new MsgForDisplay(0, AppData.getInstance().getAdMsg2()));

        topPanel.addMsg(new MsgForDisplay(0, "test top"));
        topPanel.addMsg(new MsgForDisplay(0, "test top 2"));

        adPanel.Refresh();
        msgPanel.Refresh();

    }

并且我的自定义面板(构造函数)有一些代码:

  public MyPanel(Color corLabel, Color back, Font text){
    this.color = corLabel;
    this.backg = back;
    this.textFont = text;
    this.Width = 500000;

    txt= new LinkedList<string>();
    msgs = new LinkedList<MsgForDisplay>();
    labels = new LinkedList<Label>();
    var it = labels.GetEnumerator();
    var it2 = msgToRemove.GetEnumerator();

    this.FlowDirection = FlowDirection.LeftToRight;
    this.BackColor = backg;
    this.Size = new Size(500000, 35);
    this.Refresh();

    }

跑步:

         public void run() {

         while (true) {

              var it = labels.GetEnumerator();
                while(it.MoveNext()){
               Label lb = it.Current;

                    if (lb.Location.X + lb.Width < 0) {

                        if (msgsRemover.Contains(lb.Text.ToString())) {
                            labels.Remove(lb);
                            this.Invoke(new MethodInvoker(() => { this.Controls.Remove(lb); }));
                            msgsRemover.Remove(lb.Text.ToString());
                        } else {
                            // if there is no message to be removed, they will just continue
                            // going to the end of the queue
                            this.Invoke(new MethodInvoker(() => { this.Controls.Remove(lb); }));
                            this.Invoke(new MethodInvoker(() => { this.Controls.Add(lb); }));

                        }
                        this.Invoke(new MethodInvoker(() => { this.Refresh(); }));

                    }

                    this.Invoke(new MethodInvoker(() => { lb.Location = new Point(lb.Location.X - 3, lb.Location.Y); }));

             }

             System.Threading.Thread.Sleep(30);

         }

     }

和addMsg函数:

      public void addMsg(MsgForDisplay msg) {
        Label lbl = new Label();
        lbl.Text = ("- " + msg.getText() + " -");
        lbl.ForeColor = color;
        lbl.Font = textFont;
        lbl.BackColor = backg;
        lbl.Visible = true;
        lbl.AutoSize = true;
        labels.AddLast(lbl);
        this.Controls.Add(lbl);
    }

我想这个问题必须与布局有关,但我真的不知道应该用什么...提前谢谢你的帮助!

为了解决这个问题，我删除了 flowlayout 并让面板作为面板而不是 FlowLayoutPanel，这样我就能够移动标签，不同之处在于我必须创建一个算法来在面板中添加每个标签。
