+\begin{funcdesc}{scrollbars}{\optional{wantx\, wanty}}
+Create (or destroy) horizontal and vertical scrollbars. The arguments
+specify which you want (default: both). The scrollbars always have
+minimum \code{0} and maximum \code{32767}.
+\end{funcdesc}
+
+\begin{funcdesc}{getscrollbarvalues}{}
+You must supply this method. It should return a tuple \code{x, y}
+giving the current position of the scrollbars (between \code{0} and
+\code{32767}). You can return \code{None} for either to indicate the
+whole document is visible in that direction.
+\end{funcdesc}
+
+\begin{funcdesc}{updatescrollbars}{}
+Call this method when the document has changed. It will call
+\code{getscrollbarvalues} and update the scrollbars.
+\end{funcdesc}
+
+\begin{funcdesc}{scrollbar_callback}{which\, what\, value}
+Supplied by you and called after user interaction. \code{Which} will
+be \code{'x'} or \code{'y'}, \code{what} will be \code{'-'},
+\code{'--'}, \code{'set'}, \code{'++'} or \code{'+'}. For
+\code{'set'}, \code{value} will contain the new scrollbar position.
+\end{funcdesc}
+
+\begin{funcdesc}{scalebarvalues}{absmin\, absmax\, curmin\, curmax}
+Auxiliary method to help you calculate values to return from
+\code{getscrollbarvalues}. You pass document minimum and maximum value
+and topmost (leftmost) and bottommost (rightmost) visible values and
+it returns the correct number or \code{None}.
+\end{funcdesc}
+
+\begin{funcdesc}{do_activate}{onoff\, event}
+Takes care of dimming/highlighting scrollbars when a window becomes
+frontmost vv. If you override this method call this one at the end of
+your method.
+\end{funcdesc}
+
+\begin{funcdesc}{do_postresize}{width\, height\, window}
+Moves scrollbars to the correct position. Call this method initially
+if you override it.
+\end{funcdesc}
+
+\begin{funcdesc}{do_controlhit}{window\, control\, pcode\, event}
+Handles scrollbar interaction. If you override it call this method
+first, a nonzero return value indicates the hit was in the scrollbars
+and has been handled.
