Tutorial ID:  F-TCL
  Title: The Tcl Language and the Tk Toolkit
  Time: 9:00am to 4:30pm
  Instructor: John K. Ousterhout, University of California at Berkeley
  Abstract:
    Tcl and Tk offer a new approach to constructing X applications that is both
  much simpler than alternative approaches and also much more powerful.  Tcl
  is a simple shell-like scripting language whose interpreter is implemented
  as a C library package.  Both the language and its interpreter are designed
  to be embedded in C applications.  Tk is a windowing toolkit that includes a
  Motif-like widget set.  It is implemented as a set of Tcl commands so that
  user interfaces can be constructed by writing Tcl scripts.  Together, Tcl
  and Tk provide a number of advantages for developing X applications:
  - The Tcl language provides a high-level programming environment that hides
    many of the details faced by C programmers and allows applications to be
    constructed with 5-10x less code.  Many applications can be written as
    scripts for a windowing shell without writing any C code at all.
  - Tcl scripts can be used to modify or re-program any aspect of a Tk-based
    application at run-time, including both its interface and its
    functionality.
  - Different applications can issue Tcl scripts to each other at run-time to
    achieve powerful forms of communication such as hyper-media and active
    objects.
    This tutorial will describe (a) how to write Tcl scripts, (b) how to use
  Tk's features to write Tcl scripts that generate user interfaces, (c) how to
  extend the base features of Tcl with new commands implemented in C, and (d)
  how to build new widgets and geometry managers in C using Tk.  There will
  also be descriptions of complete applications to show how all the pieces fit
  together.  Attendees should be familiar with the C programming language and
  X basics; knowledge of the Xt toolkit may be useful but is not necessary.

Tutorial ID:  F-UIL
  Title: Developing OSF/Motif User Interfaces With UIL
  Time: 9:00am to 4:30pm
  Instructor: Martin J. Schedlbauer, Schedlbauer & Associates
  Abstract:
    The User Interface Language UIL distributed with OSF/Motif has
  traditionally been avoided by Motif programmers, partly perhaps because of
  the lack of adequate documentation and tutorial information.
    However, UIL is gaining more acceptance as less experienced C programmers
  are entering the field of Motif programming. Additionally, many Motif GUI
  builders have adopted UIL as its User Interface Interchange Language.  Both
  of these trends, plus the fact that OSF has addressed many of UIL's earlier
  shortcomings, warrants that developers learn more about this important
  programming tool.
    This tutorial covers the basic structure of UIL and its use in the
  construction of graphical user interfaces. It discusses the UIL language
  syntax, the Motif Resource Manager, callback handling, widget references,
  multiple UIL source modules, internationalization features of UIL, and the
  customization of UIL through the Widget Meta Language facility.

Tutorial ID:  F-OI
  Title: Programming the Object Interface (OI) Toolkit
  Time: 9:00am to 4:30pm
  Instructor: Kuntal Rawal, Senior Software Engineer, ParcPlace Boulder
  Abstract:
    The Object Interface (OI) toolkit is a C++ based toolkit for building
  commercial quality, industry standard X applications.  A single programming
  interface is used to build binary images which can be run in Motif,
  OPENLOOK, or 3D-OPENLOOK modes.  Full C++ subclassing and member function
  callbacks are supported.  The library is completely dynamic, supporting
  dynamic reparenting of objects and dynamic resource fetching.  It comes with
  a built in hypertext help mechanism, and an interactive interface builder is
  also available.
    This course will provide you with the knowledge necessary to begin
  programming using the OI toolkit.  It will cover the mechanics of building
  the object forest, writing callbacks, using resources, adding accelerators
  and translations, and using the user interface builder (UIB) to build
  applications.
    The course is targeted at the 3.4 version of the library, now available
  from ParcPlace and independent distributors.

Tutorial ID:  F-PEXLIB
  Title: PEXlib Programming
  Time: 9:00am to 4:30pm
  Instructors: Tom Gaskins, Sound Software Development
	       Jan Hardenbergh, Oki Advanced Products
	       Charmaine Lee, SunSoft, Inc.
	       Jack Ritter, ShoGraphics, Inc.
	       Karl Schultz, IBM Corp.
	       Greg Stiehl, Kubota Pacific, Inc.
  Abstract:
    PEX has emerged as *the* 3D protocol for the X Window System.  Its new API,
  PEXlib, now allows full access to the PEX protocol and provides an extremely
  flexible interface for 3D graphics applications.  PEX features include 3D
  modeling, lighting, shading, and other advanced graphics techniques.  PEXlib
  makes it simple to access these features, and offers a collection of
  easy-to-use utilities to assist the graphics programmer.
    In this course we'll spend the morning describing PEX and PEXlib,
  explaining its major features such as the transformation and rendering
  pipelines, lighting and shading, and picking.  We'll also explain the basic
  structure of all PEXlib programs, and give the steps that all PEXlib
  programs must follow.  In the afternoon we'll put the morning's knowledge
  into practice by walking through working examples.  We'll dissect the
  simplest PEXlib program, then go on to study programs that do modeling,
  viewing, lighting, shading, and picking.  A question and answer session will
  follow.
    This tutorial is for programmers who want to learn about PEXlib and how to
  program with it.  It's structured so that those wanting only an overview and
  explanations can attend just the morning session.  Those that want practical
  examples can attend both the morning and afternoon sessions.  The schedule
  is as follows:
    Morning: A Comprehensive Introduction to PEX and PEXlib
  1) Introduction: What PEX and PEXlib are; PEX Concepts and Resources; PEX
     Overview (primitives, structures--the basics); PEXlib Overview
  2) The Graphics Pipeline: The Renderer; The Transformation Pipeline
     (modeling and viewing); The Rendering Pipeline (lighting, shading, depth
     cueing); Color Approximation;
  3) Advanced Topics: Picking; Double Buffering
  4) Questions & Answers
    Afternoon: PEXlib Programming Examples
  1) The Basic PEXlib Program
  2) Modeling and Viewing Examples
  3) Lighting, Shading, and Double Buffering Examples
  4) Questions & Answers 
    All instructors have extensive experience with PEX and with PEXlib
  programming.

Tutorial ID:  F-ADMIN
  Title: X and the Administrator
  Time: 9:00am to 4:30pm
  Instructors: Dinah McNutt, Customer Service Consultant, Tivoli Systems, Inc.
	       Miles O'Neal, Senior Software Engineer, Pencom Software
  Abstract:
    This tutorial provides an overview of X for the system administrator.  It
  covers common, day-to-day, practical system administration issues related to
  X, primarily in a UNIX environment.  Along with generic topics,
  vendor-specific issues are also covered.
    Topics covered include: components overview, where files are located and
  what they do, the |user environment, color management, X terminals,
  maintaining source code, fonts, imake, managing multiple versions of X,
  security, and troubleshooting.  Time is allowed for Q&A.  Sample scripts,
  setup files, and Imakefiles are provided.
    While primarily targeted at system administrators, much of the information
  is also useful for users and developers.

Tutorial ID:  A-GUI-TIPS
  Title: Tips on Designing Graphical User Interfaces
  Time: 9:00am to 12:00noon
  Instructor: Jarrett Rosenberg, SunSoft, Inc.
  Abstract:
    Developers designing a graphical user interface are usually faced with
  information and guidelines that are either too low-level (e.g., widget
  API's) or too abstract (e.g., most books on user interface guidelines).
  This tutorial fills that gap by presenting a specific design methodology as
  well as numerous tips on such issues as how to make an easily readable
  window layout, or how to choose among alternative widgets.  The intent is to
  provide developers with a useful bag of tricks that will easily yield
  improvements in user interface quality.  Examples in the course will be
  drawn from the Athena widgets, OPEN LOOK, and Motif.

Tutorial ID:  A-MOTIF-INTRO
  Title: Introduction to Motif Programming
  Time: 9:00am to 12:00noon
  Instructor: Eric F. Johnson, CAMAX Systems, Inc.
  Abstract:
    The Motif toolkit, from the Open Software Foundation, is one of the most
  popular programming toolkits for the X Window System.  Most UNIX and
  workstation vendors, including IBM, Hewlett-Packard, Silicon Graphics,
  Digital Equipment and SCO--with the notable exception of Sun
  Microsystems--endorse Motif and include the Motif toolkit with their
  systems.
    This practical tutorial provides an introduction to programming with the
  Motif toolkit. We'll focus on developing C language programs using the Motif
  library.
    The tutorial will introduce Motif programming, delve into common problems
  faced by developers, cover a number of example programs and show you how to
  go beyond the basics in your own applications.

Tutorial ID:  A-IMAKE
  Title: I make, you make - Using Imake in Application Development
  Time: 9:00am to 12:00noon
  Instructor: Rainer Klute, Dortmund University, Computer Science Dept.
  Abstract:
    The Imake utility, used by the X Consortium to compile and install the X
  Window System on a broad range of different platforms, and included in the
  X11 source distribution, is also very useful for your own program
  development.  Unfortunately documentation on Imake is rare and the online
  manual page is of no help for the beginner.
    This tutorial helps fill the gap.  It is directed to application developers
  first of all.  In the first part you will learn why you should use Imake,
  how to use Imake with an existing Imakefile (the counterpart of a Makefile),
  and how to write your own Imakefiles.  We shall examine some sample
  Imakefiles starting from a simple one proceeding to higher complexity,
  including the management of source directory hierarchies.  In a second part
  I shall explain how Imake does its job and how to write your own Imake
  rules.  Finally the tutorial will present Imake-pure, an Imake without X. To
  make full use of the tutorial you should have an idea about what "make" is
  and what it does.

Tutorial ID:  A-SECURITY
  Title: A Survey of X and Security
  Time: 9:00am to 12:00noon
  Instructors: Jeremy Epstein, TRW Systems Division
	       Rita Pascale, ORA Corp.
  Abstract:
    As the X Window System increases in popularity, so do concerns about its
  security implications.  X's basic notion is of openness, which is in direct
  contrast to many security requirements.  While X promotes "mechanism without
  policy" for its graphical interface, in the area of security it is largely
  "policy without mechanism."
    This tutorial explains the security risks involved in using X, and some of
  the solutions currently available and expected in the future.  It is not a
  "how to" course, but rather "what" and "why".  Security is considered from
  both commercial/academia and government/military standpoints.  Topics to be
  covered include threats, issues, authentication, access controls, auditing,
  integrity, privilege, denial of service, and the basics on how to use the
  solutions.
    A brief introduction to security goals and terminology will be provided, so
  no previous experience with security is required.  A very short review of X
  terminology will suffice for those not already familiar with the X
  architecture.  This tutorial is appropriate for managers (especially those
  concerned with security) as well as programmers.

Tutorial ID:  A-VIDEO
  Title: Video Compression: Basic Technology and Applications in X
  Time: 9:00am to 12:00noon
  Instructor: Todd Brunhoff, North Valley Research
  Abstract:
    Media, the kind used for storage and for presentation on computers, has
  always been the item of interest among the common user, because media is the
  catalyst for change in the way we use computers.  From tapes to floppies,
  teletypes to graphics monitors, single images to video, the change in media
  changes computer use.  Video has been available on computers since about
  1985 in analog form, but in the last two years, general computers and low
  cost chips have both become fast enough to handle digital forms of video in
  real time.  This tutorial will cover some of the basic technologies in
  analog and digital video, then review the basic compression methods applied
  to motion sequences: transforms, quantization, entropy coding and motion
  compensation.  We will look at the current set of standards (JPEG, MPEG,
  H.261, MPEG II) and see how each gets applied.  Finally, there will be a
  review of the current state of technology in computers, a demonstration on a
  workstation, and a short video tape.

Tutorial ID:  A-OLIT-DESKTOP
  Title: Desktop Integration using OLIT & ToolTalk
  Time: 9:00am to 12:00noon
  Instructors: Amy Moore, Member of Technical Staff, OLIT, SunSoft, Inc.
	       John Fowler, Manager of Technical Staff, DeskSet, SunSoft, Inc.
  Abstract:
    This tutorial is for Intrinsics programmers who are interested in writing
  advanced OLIT applications that take advantage of desktop integration
  features in the Solaris OpenWindows environment, such as Drag&Drop and
  ToolTalk messages.  The tutorial will explain how to program OLIT
  applications to communicate with other applications on the desktop (focusing
  on the DeskSet), covering:
  I.   Overview of Desktop Integration in OpenWindows
  II.  Integrating Drag&Drop support into an OLIT Application
  III. Integrating Tooltalk communication with DeskSet into an application 
    Attendees should be familiar with ANSI C, the X11 Window system and Xt
  programming (including the X11/Xt Selection mechanism).  Familiarity with
  the OpenWindows DeskSet and OLIT toolkit programming is helpful.

Tutorial ID:  P-WCL
  Title: X Application Evolution using Wcl 2.3
  Time: 1:30pm to 4:30pm
  Instructor: David E. Smyth, research grant from Esprit Investments Ltd;
		primary sponsor Siemens Nixdorf Informationssysteme
  Abstract:
    The author of Wcl will present this tutorial on the latest release of the
  Widget Creation Library.  A short introduction will be made for the benefit
  of those not yet familiar with Wcl, but the majority of the material will
  cover techniques and advanced concepts.
    Topics covered will include: Building the Wcl distribution, establishing a
  development environment, specific techniques for developing prototypes,
  specific techniques for evolving applications from such prototypes, as well
  as debugging tools and support.  The techniques presented are the result of
  using Wcl "in the trenches" - software development projects for governments
  and commercial customers, with real requirements, real deadlines.
    The tutorial covers alot of information: over 150 viewgraphs.  In addition,
  a limited number of floppies containing the latest Wcl source distribution
  will be available for those without reliable ftp access.

Tutorial ID:  P-POWER-TOOLS
  Title: Motif Power Tools
  Time: 1:30pm to 4:30pm
  Instructors: David Flanagan, partner, Dovetail Interface Consulting,
			author, O'Reilly & Associates
	       Alvin Wen, partner, Dovetail Interface Consulting
  Abstract:
    The Motif widget set is not programmer-friendly.  For the past year, I've
  been developing and refining a library of Motif "power tools" that
  dramatically simplifies many aspects of Motif and Xt programming.  This
  library has its roots in a suite of Motif utilities I wrote at MIT's Project
  Athena.  It will be released (as shareware) before the conference, and will
  also be available for free with my book "Motif Power Tools", forthcoming
  later in 1993 from O'Reilly & Associates.  This tutorial is an extended
  overview of the capabilities of the library, and will be sufficient to get
  any programmer started with it.
    Features of the library include: Simple message display--functions to
  display information, warning and error messages, with automatically created
  and cached dialog boxes.  Simple "blocking" input--functions to
  synchronously return strings, numbers, booleans, filenames, etc.  with
  automatically created and cached dialog boxes.  The XmtMenu widget--describe
  a menu with an array of structures, or with a single resource in a resource
  file.  The XmtChooser widget--a single widget that can appear as a radio
  box, a check box, a list widget, a palette, or an option menu.  Takes an
  array of strings or pixmaps to display as the choices, and maintains a
  single state variable.  The XmtCli widget--a "command line interface" with
  automatic prompting and command history.  Has fprintf() and fgets() analogs
  for porting terminal-based applications.  The XmtMsgLine widget--a message
  line inspired by emacs.  Supports synchronous input.  The XmtInputField
  widget--a text widget with accompanying caption and input validation.  The
  XmtLayout widget--a general manager widget, using the TeX boxes-and-glue
  layout algorithm.  Layout can be specified with a single string resource.
  Simpler than the Form widget, and more flexible than the popular Table
  widget; includes built in support for text and pixmap labels, separators and
  shadowed frames.  Online help--structured document browsing with the
  XmtHelpBrowser widget, and context-sensitive help with resource files and
  the simpler XmtHelpBox widget.  Support for multi-color pixmaps using the
  XPM format and a new datatype, the XmtColorTable.  Wcl-style automatic
  widget creation with improved syntax, templates and "styles".  Also, an
  improved callback converter.  Automatic dialog creation--register a resource
  list when you create a dialog, and have the dialog automatically store its
  data in a specified location.

Tutorial ID:  P-DPS
  Title: Using the Display PostScript Extension to X
  Time: 1:30pm to 4:30pm
  Instructor: Paul Asente, Adobe Systems Inc.
  Abstract:
    The Display PostScript Extension, or DPS/X, brings many useful capabilities
  to the X Window System.  Among these are typographic font handling, image
  manipulation, resolution independence, additional drawing functions,
  exchange of graphics among applications, and previewing PostScript language
  documents.  It also provides device independence; applications can draw in
  color without regard to the basic capabilities of the actual display being
  used.  This tutorial introduces the basic concepts used in the extension,
  covers the various ways an application can interact with DPS/X, and provides
  useful programming tips.  Basic knowledge of PostScript language programming
  will be helpful but not necessary.

Tutorial ID:  P-VISUAL-DESIGN
  Title: Applying Visual Design - or How to Look Good in Pixels
  Time: 1:30pm to 4:30pm
  Instructors: Kevin Mullet, Darrell Sano, SunSoft, Inc.
  Abstract:
    Functional and aesthetic goals are often viewed as irreconcilable
  alternatives, but they need not be in conflict.  Information-oriented
  graphic design - or visual communication design - always works within the
  boundaries set by standards of usability and human performance to create
  results that achieve effective communication while inspiring, enlightening,
  or simply providing the user with an enjoyable aesthetic experience. This
  tutorial looks at universal concepts of beauty and elegance and examines
  their implications for graphical user interfaces and data displays. We focus
  on principles of aesthetic quality that have proven to be truly universal -
  those that continue to hold true across many different styles over extended
  periods of time - rather than on personal aesthetic statements or artistic
  biases. We show how these principles are applied to achieve good results in
  a wide variety of different styles, even in the absence of extensive formal
  training in the visual design disciplines.
    The communication-oriented design aesthetic seen in graphic design,
  industrial design, and architecture can be applied very successfully to
  graphical user interfaces, data displays, and multimedia documents.  This
  tutorial will focus on providing an understanding of the core competencies
  or "tricks of the trade" that all students of visual design internalize as
  part of their basic training. The tutorial is organized not along the
  traditional graphic design specializations such as color or typography, but
  according to the design goals and familiar problems of real-world product
  development.  Specific content areas include: elegance and simplicity;
  scale, contrast and proportion; organization and visual structure; module
  and programme; image and representation; and style.
    This tutorial will be useful to anyone responsible for designing,
  specifying, implementing, or managing the visual appearance of
  computer-based information displays who does not have extensive formal
  training in visual design or access to professional design services. Graphic
  designers will be familiar with the material presented here but may find the
  application to human computer interface work of interest.

Tutorial ID:  P-OLIT-I18N
  Title: Advanced OLIT Programming: Internationalization
  Time: 1:30pm to 4:30pm
  Instructors:
	David Curley, OLIT I18N Project Lead, SunSoft, Inc.
	John Pew, Software Consultant & OLIT Specialist, Vivid Solutions Corp.
	Hideki Hiura, Windows I18N Engineer, SunSoft, Inc.
  Abstract:
    This tutorial is for Intrinsics programmers who are interested in writing
  OLIT applications for international markets.  The student will learn how,
  with a little planning, it is straightforward to produce an
  internationalized OLIT application, which can then be localized for many
  European and Asian markets.
    The tutorial will be conducted in three sessions:
  1) Internationalization support in OLIT: locale announcement; text storage
     formats; displaying localized text; input of localized text; checklist
     for application developers
  2) Designing International OLIT Applications: practical application of I18N
     techniques; localization techniques; internationalization process, with
     examples; hints and tips
  3) Input Methods: reason for complex input methods; summary of X11R5 XIM
     support; input method architecture; toolkit interaction with input method
  Prerequisites: Attendees should be familiar with ANSI C, the X11 Window
  system and Xt programming. Basic understanding of internationalization
  concepts is helpful, but not required.  Knowledge of OLIT is helpful.

Tutorial ID:  P-SYNC
  Title: The Use and Abuse of the X Synchronization Extension
  Time: 1:30pm to 4:30pm
  Instructor: Tim Glauert, Olivetti Research Ltd.
  Abstract:
    This tutorial will cover all aspects of the (proposed) X Synchronization
  Extension, of which I am the Architect.
    It will start with an overview of the typical applications which require
  synchronization and will discuss the issues involved. It will outline the
  shortcomings of the Core Protocol which make the Extension necessary, or at
  least desirable.
    It will cover the basis of the Extension by describing the Counter and
  Alarm objects and the Await primitive. The tutorial will then describe the
  details of the extension, including the Library interface, the Protocol
  details and the view from the position of a Server Implementor or an
  Extension writer who wishes to take advantage of the features of the
  extension.
    Finally, the Tutorial will look at the implementation details of some
  typical applications which use the Extension, including its use within the
  multi-media work at Olivetti Research.
    I intend the atmosphere of the tutorial to be informal to allow the
  maximum amount of feedback and questions from the "floor".
