在mobile5.0上实现滑动效果控件

最近一直忙于IM的设计，很久没有更新我的博客。今天有点时间，我把以前做的一个mobile5滑动效果放上来与大家分享，希望能对初学者有一点帮助。

用过mobile的朋友都知道微软的联系人这个软件很不好用，采用的是pc那种方式，右边一个滚动条，而这个滚动条又太细，我的拇指经常性的点不中，所以萌发了写个类似Iphone那种滑动效果的控件。

控件是用C#和GDI+写的，内部有一个简单的状态机制，没有什么技术含量。我也不打算仔细给大家讲解了，看代码吧。

代码主要有三个类：

 1.QQListControl : 继承与UserControl，是个用户控件。

 2.Column：控件列名，支持自定义列。

 3.ListLab：分组标签。考虑到手机屏幕大小，分组标签一段时间后会自动折叠，仅显示当前标签。

典型是用代码如下：
