给Revit中的Button添加动画和图片

    测试环境Revit2016;

    引用Revit的DLL有RevitAPI.dll，RevitAPIUI.dll，AdWindows.dll，UIFramework.dll.

    如何实现像Revit自带的命令一样，当鼠标长停在button上，出现动画或者图片（如图1）。

    查看RevitAPIUI.dll中的  Autodesk.Revit.UI.PushButtonData，发现revit提供了ToolTipImage属性，但是它只能添加图片，无法添加动画，所以我们要使用AdWindows.dll提供的Autodesk.Windows.RibbonItem，来给ToolTip属性赋值。

    这个方法的关键是找到Autodesk.Windows命名空间下的RibbonItem,本文将提供两种方式，一种是遍历Autodesk.Windows.RibbonControl，第二种是通过Autodesk.Revit.UI.RibbonItem反射查找Autodesk.Windows.RibbonItem。

    使用C:/Program Files/Autodesk/Revit 2016/videos/目录下的视频文件（根据Revit安装目录查找文件），最后实现效果如图2。
