 - 按键映射中的坐标位置都是用相对位置表示的，屏幕的宽高都用1表示，例如屏幕的像素为1920x1080，那么坐标(0.5,0.5)则表示的是
 以屏幕左上角为原点，像素坐标(1920,1080)*(0.5,0.5)=(960,540)的位置。

+    或者鼠标左键单击时控制台会输出此时的pos，直接使用这个pos即可

 - 按键映射中的按键码是用Qt的枚举表示的，详细说明可以[参考Qt文档]( https://doc.qt.io/qt-5/qt.html )(搜索 The key names used by Qt. 可以快速定位)。
 - 开发人员选项中打开如下两个设置，可以方便的观察触摸点的坐标：
