private static boolean isInHorizontalTargetZone ( float x , float y , float handleXStart , float handleXEnd , float handleY , float targetRadius ) { return x > handleXStart && x < handleXEnd && Math . abs ( y - handleY ) <= targetRadius ; }
determines if the specified coordinate is in the target touch zone for a horizontal bar handle .
