gk::scrollbar ?scrollbar-options? pathName
The multi-user scrollbar is a groupware version of a conventional Tk scrollbar. Alongside the normal scrollbar is a thin canvas which displays a set of rectangles, one for each user in the conference. These rectangles track the position of each user's own scrollbar though the document, providing a sense of awareness of what areas of the document others are scrolled to.The gk::scrollbar command provides a drop-in replacement to Tk's scrollbar command. It accepts the same set of configuration options, and the widget command is used in the same way.
