上一次挑战杯我们用kinect1.8做了一个体感3d试衣系统，那时就想用qt来开发了，由于那时候很多东西都不懂，怎么也不知道怎样去配置环境，只能在vs2013中开发，结合qt开发界面。直到出了kinect2.0后才配置成功完全用qt 来开发Kinect！而且完美运行。注意一点就是使用的qt必须是
qt forwindows msvc的才能正常编译。
kinect 2.0开发系统要求：win8.1以上
kinect 1.8开发系统要求：win7以上

实现kinect功能代码，本代码功能是实现了右手当作鼠标来操控程序，当手握紧相当于鼠标按下左键，当手控制鼠标悬停在某个按钮的时候，相当于鼠标的点击事件。
