- GLUT NOTE: The GLUT API version 2 & 3 X11 implementations support the SGI
- Dials and Buttons, SGI Spaceball, and SGI Tablet via the X Input
- extension. These devices are advertised as described below. If other
- vendors advertise these X Input extension devices differently, GLUT's X
- implementation will need to be extended to properly support such
- differently advertised devices.
- X Input Extension Devices as Advertised by Silicon Graphics
- Mark Kilgard
- February 13, 1995
- $Revision: 1.2 $
- This document describes how Silicon Graphics Inc. (SGI) advertises its
- support for input devices through the X Input extension. Because the X
- Input extension only provides mechanism for supporting additional X
- input devices, vendors may support the same or similar devices in
- slightly different ways making it difficult for programs to count on
- how a given input device will be supported across vendors.
- The intent of this document is not to propose any standard way of
- supporting specific X Input extension devices, but merely to thoroughly
- describe SGI's X Input support for the benefit of X Input programmers
- and other X Input extension implementors wishing to mimic SGI's X Input
- support to avoid needless incompatibility for otherwise standard and
- common input devices.
- The client queriable state returned by the X Input extension is not
- enough to effectively use X Input extension devices. The physical
- layout of how the dials, axes, buttons, etc. are laid out is not
- queriable. Effective use of the extension requires knowledge of the
- physical layout of the devices. Diagrams are provided to show the
- actual layout.
- Comments and corrections should be sent to Mark Kilgard <mjk@nvidia.com>

- Peter Daifuku <daifuku@sgi.com) if you need to contact SGI about this
- information.)
