    Patent number: 6512530
    Abstract: A graphical user interface widget includes a vertically-oriented slider portion. The slider portion includes a slider pointer that indicates a current value of the slider and a slider bar that indicates the default value of the slider. The bottom and top edges of the slider portion are labeled with the extreme values of the range for the variable associated with the slider portion. The slider pointer divides the slider portion into two subportions. An appearance of a bottom subportion of the slider portion is altered to reflect the value currently indicated by the slider pointer relative to the extreme values of the range represented by the slider. A numerical portion can be provided along with the slider portion. The numeral portion includes a value display portion and a pair of buttons that are used to increase or decrease the numerical value in the value display portion.
