10.14. Identifying Parts of a ScaleTo find out what part of the Scale a coordinate resides in, use the identify method: $value = $scale->identify(x, y); The identify method returns a string containing one of the following values: "slider", "trough1", "trough2", or an empty string (if the coordinates don't refer to any of these parts).
