[問題] 關於 使用Panel 表現圓形移動的方法

[asail0712 (emeth)]

以下為使用Timer 跟 Panel 的程式碼...

可是沒有顯示出我想要的結果

請問是我哪理觀念錯了嗎??

  public partial class Form1 : Form
    {
        int status;
        static int x;
        int y;
        System.Windows.Forms.Timer myTimer = new System.Windows.Forms.Timer();
        static bool exitFlag = false;


        public Form1()
        {
            InitializeComponent();
            status = 1;
            x = 25;
            y = 25;
        }



        private void panel1_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            Pen pen = new Pen(Color.Blue);
            if (status == 0)
            {
                g.DrawPie(pen, x, y, 15, 15,0,360);
            }
        }
        private void TimerEventProcessor(Object myObject, EventArgs myEventArgs)
        {
            x += 5;
            myTimer.Stop();
            panel1.Invalidate();
            myTimer.Enabled = true;
            if(x==100)
            {
                exitFlag = true;
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            myTimer.Tick += new EventHandler(TimerEventProcessor);

            myTimer.Interval = 500;
            myTimer.Start();

            while (exitFlag == false)
            {
                Application.DoEvents();
            }
        }
    }
