0)简述:鉴于本论坛有人提示需要实现类似Word标注的ToolTip,TFSoft近日已经实现。现将源代码无偿奉献。主要特点:01)自动适应提示内容,02)自动调整提示位置,自动调整标准箭头方向,03)用法与ToolTipService一样(采用附加属性实现),04)有多种标注方式(椭圆形、云形、方形、圆角方形),05)比ToolTipService公开了更多的附加属性。

注意:引用了Expression Blend 的一个DLL(C:\Program Files\Microsoft SDKs\Expression\Blend\Silverlight\v4.0\Libraries\Microsoft.Expression.Drawing.dll)

1)主要程序文件(T4CtATToolTipService.cs):
