Parameters

Parameter	Type	Description
location	LeadPointD	The location of the thumb to test in container coordinates.
testPoint	LeadPointD	The point to test in container coordinates.
hitTestBuffer	double	The hit test buffer is used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if the buffer value is 2, a square with a length of 4 units around the test point will be used to perform the hit-testing. This value is in container coordinates.

Return Value

The automation framework will call HitTest repeatedly to determine if a user input location is over a thumb. For example, to determine if the framework should start dragging a side of a selected object or to start rotating it.
