- Method Detail
  - computeHorizontalScrollRange
```
 abstract int computeHorizontalScrollRange()
```
    Compute the horizontal range that the horizontal scrollbarrepresents.
    The range is expressed in arbitrary units that must be the same as theunits used by computeHorizontalScrollExtent and computeHorizontalScrollOffset.
    The default range is the drawing width of this view.
  - computeHorizontalScrollOffset
```
 abstract int computeHorizontalScrollOffset()
```
    Compute the horizontal offset of the horizontal scrollbar's thumbwithin the horizontal range. This value is used to compute the positionof the thumb within the scrollbar's track.
    The range is expressed in arbitrary units that must be the same as theunits used by computeHorizontalScrollRange and computeHorizontalScrollExtent.
    The default offset is the scroll offset of this view.
  - computeHorizontalScrollExtent
```
 abstract int computeHorizontalScrollExtent()
```
    Compute the horizontal extent of the horizontal scrollbar's thumbwithin the horizontal range. This value is used to compute the lengthof the thumb within the scrollbar's track.
    The range is expressed in arbitrary units that must be the same as theunits used by computeHorizontalScrollRange and computeHorizontalScrollOffset.
    The default extent is the drawing width of this view.
  - computeVerticalScrollRange
```
 abstract int computeVerticalScrollRange()
```
    Compute the vertical range that the vertical scrollbar represents.
    The range is expressed in arbitrary units that must be the same as theunits used by computeVerticalScrollExtent and computeVerticalScrollOffset.
  - computeVerticalScrollOffset
```
 abstract int computeVerticalScrollOffset()
```
    Compute the vertical offset of the vertical scrollbar's thumbwithin the horizontal range. This value is used to compute the positionof the thumb within the scrollbar's track.
    The range is expressed in arbitrary units that must be the same as theunits used by computeVerticalScrollRange and computeVerticalScrollExtent.
    The default offset is the scroll offset of this view.
  - computeVerticalScrollExtent
```
 abstract int computeVerticalScrollExtent()
```
    Compute the vertical extent of the vertical scrollbar's thumbwithin the vertical range. This value is used to compute the lengthof the thumb within the scrollbar's track.
    The range is expressed in arbitrary units that must be the same as theunits used by computeVerticalScrollRange and computeVerticalScrollOffset.
    The default extent is the drawing height of this view.
