Remarks

Note

This class is not agile, which means that you need to consider its threading model and marshaling behavior. For more info, see Threading and Marshaling (C++/CX).

Properties

BoundingBox	Gets the bounding rectangle of the touch contact area.
Handled	Gets or sets a value indicating whether the TouchHitTesting event was handled.
Point	Gets the screen coordinates of the touch point reported by the touch digitizer.
ProximityEvaluation	Gets or sets the proximity evaluation score for an object relative to the touch contact area.

Methods

EvaluateProximity(Point[])	Returns a ranking for the polygon as the probable touch target and an adjusted touch point within the polygon. The rank is determined through a comparison of targeting heuristics for all polygons that intersect the touch contact area.
EvaluateProximity(Rect)	Returns a ranking for the rectangle as the probable touch target and an adjusted touch point within the rectangle. The rank is determined through a comparison of targeting heuristics for all rectangles that intersect the touch contact area.
