ScrollBar 

The ScrollBar is a standard Motif widget that is always attached to a Scrolled-
Window. The ScrolledWindow provides a movable view into a window that has more 
contents than can be displayed at one time due to the size of that window. The 
ScrollBar controls the contents displayed by a ScrolledWindow. A ScrolledWindow 
usually has at least one ScrollBar. Most ScrolledWindows in Sun MTPScan display both
horizontal and vertical ScrollBars at all times, whether they are needed or not.
That way, the ScrollBars don't magically appear and disappear as you resize a
window. A ScrollBar can be attached to any side of the ScrolledWindow. The 
ScrolledWindow can also be resized to see more or less of the window's contents,
as you desire. The ScrollBars adjust to accommodate the new size.

There are four components to each ScrollBar: two ScrollBarArrows, a 
ScrollBarSlider, and a ScrollBarTrough. Each ScrollBar component scrolls a 
ScrolledWindow's contents in one way or another. Each of these components has 
its own descriptive Help entry.
