功能简介

  当语音客服系统登录成功进入主界面时，本聊天工具将会自动隐藏在左下角位置，当鼠标移动到左下角时，自动弹出，当鼠标移开聊天窗体时，自动隐藏。如果想让聊天窗体固定在桌面，只要拖动一下聊天窗口，让它不停留在边界位置就可以了。隐藏和悬浮方式类型QQ。

1. 系统主界面

当点击最小化按钮时， 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”按钮，将进行消息发送。

c) 坐席人员：显示所有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：
