C#的TabControl模擬IE7程序事例,帶關閉功能

在csdn下載了一個類似ie7的功能，使用的是默認的TabControl控件  窗體算比較醜  功能是實現了  廢話不多說 貼代碼

1：先上圖

2：貼代碼

            }
            if (this.tabControl1.SelectedIndex == 0) return;

                if (closeRect.Contains(new Point(e.X, e.Y)))
                {
                    this.tabControl1.TabPages[this.tabControl1.SelectedIndex].ImageIndex = 1;
                    Application.DoEvents();
                }
            }
        
        }

        private void tabControl1_MouseLeave(object sender, EventArgs e)

功能還需完善  思路已出
