Detailed Description

Interface to a scrollbar GUI element.

These are the GUI elements often displayed at the right or bottom of a window, to allow changing the position of the currently viewed document. These are not the same as a slider GUI element, although there is similarity. The values used within the scrollbar (scroll position, scroll size) are only used by the GUI system to position the thumb, the range of values used are meaningless to the GUI, allowing it to have meaning for the application.
