Description
This function is used to set the maximum distance between an EVT_POINTER_DOWN and an EVT_POINTER_UP event. This is one of the criteria to be satisfied for single tap detection, and can be used simultaneously with the Max Tap X/Y Dif; as long as either criteria is met, it will be considered a tap.
Parameters

    []:
    [in] Pointer to the IObserver interface object.
  • nMaxTapRadius
    []:
    [in] MaxTapRadius value to be set.
