Remarks

- ToolTipHitTest(IEnumerableIMapObject, Point, Double) implements the basic hit test on LayerObject information objects. Elements within a range of 10 pixels (measured taking either the reference point or the full response geometry into account - depending on what actually is available) qualify for tool tip display. Depending on the xMap content requested you may want to change this behavior. ToolTipHitTest(IEnumerableIMapObject, Point, Double) can be overridden in derived classes.
