button按下松开只有按下事件(WM_NOTIFICATION_CLICKED),和移除区域事件(WM_NOTIFICATION_MOVED_OUT),而没有(WM_NOTIFICATION_RELEASED)
GUI_TOUCH_GetState(&TouchState); // Get the touch position in pixel
xPhys = GUI_TOUCH_GetxPhys(); // Get the A/D mesurement result in x
yPhys = GUI_TOUCH_GetyPhys(); // Get the A/D mesurement result in y
通过这三个接口测试发现,按下时TouchState.x,TouchState.y与xPhys ,yPhys 是对应得上的。但是松开之后,xPhys ,yPhys 变为零,此为物理值为0正常,但是TouchState.x也会变为零应该为异常,导致触发WM_NOTIFICATION_MOVED_OUT事件。TouchState.y值保持原值没变
