上一次挑戰杯我們用kinect1.8做了一個體感3d試衣系統，那時就想用qt來開發了，由于那時候很多東西都不懂，怎么也不知道怎樣去配置環境，只能在vs2013中開發，結合qt開發界面。直到出了kinect2.0后才配置成功完全用qt 來開發Kinect！而且完美運行。注意一點就是使用的qt必須是
qt forwindows msvc的才能正常編譯。
kinect 2.0開發系統要求：win8.1以上
kinect 1.8開發系統要求：win7以上

實現kinect功能代碼，本代碼功能是實現了右手當作鼠標來操控程序，當手握緊相當于鼠標按下左鍵，當手控制鼠標懸停在某個按鈕的時候，相當于鼠標的點擊事件。
