What are the gesture metrics built into the Windows gesture recognizer?
问题 I started looking for the touch equivalent of GetSystemMetrics(SM_CXDOUBLECLK | SM_CYDOUBLECLK) , but any list of values will do. So far I have found these: https://msdn.microsoft.com/en-nz/library/ee500273.aspx 回答1: That structure isn't part of Windows any more. The current structures are internal to Microsoft; however, the current values are: 200 himetric units in X and Y for the touch to be considered a tap; 450 himetric units in X and Y for two taps to be considered a double tap. 来源:
