由于项目需要，今天写了一个鼠标提示类，现在共享出来，欢迎大家探讨。

使用示例：

import cn.asarea.tool.*;
ToolTip.stage = stage;
//ToolTip.setTipProperty(0xcccccc, 15, 300, 0xcccccc, 0x333300);
ToolTip.BindDO(tipDO1, "欢迎访问http://www.asarae.cn");
ToolTip.BindDO(tipDO2, "ATHER Shu");
//ToolTip.hideToolTip();
//ToolTip.showToolTip();
//ToolTip.removeToolTip();
//ToolTip.LooseDO(tipDO1);
ToolTip.setDOInfo(tipDO2, "say hello to AS");

/**
*Author: ATHER Shu 2008.7.15
* ToolTip类: 鼠标提示类
* 功能：
* 1.绑定某DisplayObject以显示鼠标提示 BindDO
* 2.去除某DisplayObject绑定 LooseDO
* 3.动态更改某DisplayObject鼠标提示信息 setDOInfo
* 4.测试某DisObject是否已经绑定 TestDOBinding
* 5.动态隐藏所有鼠标提示 hideToolTip
* 6.动态显示所有鼠标提示 showToolTip
* 7.清空所有鼠标提示 removeToolTip
* 8.设定全局鼠标提示样式 setTipProperty
