The ScrollBar class is the base class for the HScrollBar and VScrollBar controls. A ScrollBar consists of two arrow buttons, a track between them, and a variable-size scroll thumb. The scroll thumb can move by clicking on either of the two arrow buttons, dragging the scroll thumb along the track, or clicking on the track.

The width of a scroll bar is equal to the largest width of its subcomponents (up arrow, down arrow, thumb, and track). Every subcomponent is centered in the scroll bar.
