Declaration
func indexOfTickMark(at point: NSPoint) -> IntParameters
- point:
The point representing the slider location.
Return Value
The index of the tick mark closest to the specified location.
Discussion
If point is not within the bounding rectangle (plus an extra pixel of space) of any tick mark, the method returns NSNotFound. This method calls rectOfTickMark(at:) for each tick mark on the slider until it finds a tick mark containing point.
