Configuring scrollbars

\c{ The actual construction and geometrical layout of the tablet widget involves the creation of a canvas and two scrollbars. As expected, the path of the canvas corresponds with the path given to redirect. The 3D appearance of the canvas is then determined and its screen geometry and region of scrollable surface is set (a). Scrollbars are by default vertically oriented. A horizontal orientation must be explicitly indicated (b). The order of packing the scrollbars and canvas is important. Finally, the scrollbars must be attached to the canvas (c). }
