Detailed Description

A scrollbar attached to a scroll area.

A WScrollArea always has two scrollbars (even if they are not visible, for example when the policy is WScrollArea::ScrollBarAlwaysOff). Using the tie(WScrollBar *one, WScrollBar *two) functions, it is possible to tie to scrollbars together, so that they will scroll together.
