我正在用kinect和arduino做一个“简单”的项目，但我找不到这样做。
我正试图在手悬停KinectTileButton时触发一个函数，而不是鼠标。
到目前为止我的代码：

如果我使用MouseEnter和MouseLeave事件，它可以工作，但对于这个项目的propouse，我必须使用kinect。此外，点击事件有效，但这不是我需要的。
答案 0 :(得分：0)
使用Kinect SDK Samples中的ControlBasics，我发现悬停的推荐者有一个按钮。
<local:KinectHoverButton Grid.Column="0" Style="{StaticResource KinectHoverButtonScrollLeftStyle}" Click="PageLeftButtonClick" IsEnabled="{Binding ElementName=ControlsBasicsWindow, Path=PageLeftEnabled}"/>
使用此按钮时，当您将鼠标悬停时，click事件将起作用。
