C#实现相似QQ的隐藏浮动窗口、消息闪动

功能简单介绍

  当语音客服系统登录成功进入主界面时，本聊天工具将会自己主动隐藏在左下角位置，当鼠标移动到左下角时，自己主动弹出，当鼠标移开聊天窗口时，自己主动隐藏。假设想让聊天窗口固定在桌面。仅仅要拖动一下聊天窗口，让它不停留在边界位置就能够了。

隐藏和悬浮方式类型QQ。

1. 系统主界面

   

当点击最小化button时， 在电脑右下角会显示任务图标，点击任务图标，将会在左下角位置弹出。

主界面各部分介绍：

a) 消息列表：该区域的功能主要是显示消息记录。

b) 发送消息：输入要发送的消息进行发送，默认群聊。输入消息后，按回车键或者点击“发送”button，将进行消息发送。

c) 坐席人员：显示全部已登录客服系统的坐席人员，显示方式：名称（状态）

d) 通知：记录坐席上下线记录

实现浮动：

        internal AnchorStyles StopDock = AnchorStyles.None;

        private void StopRectTimer_Tick(object sender, EventArgs e)

                switch (this.StopDock)
