--------------------------------------------------------------------------
The 3rd annual Technical Conference on the X Window System will be held
January 23-25 at MIT. The conference is sponsored by the MIT X Consortium.
The purpose of the conference is to present and discuss leading edge research
and development in the X environment from both academia and industry.
The conference will consist of tutorials, presentations, and "Birds of a
Feather" sessions for general discussion of specific areas of interest. There
will be no "trade show" attached to this conference.
The conference will be free, but registration is *required* in order to attend
tutorials and presentations. All tutorials will be held Monday, January 23,
with presentations on Tuesday and Wednesday, January 24-25.

Programming User Interfaces in C++ with InterViews
Paul Calder, Stanford University
In this tutorial we describe InterViews, a C++ toolkit for X that we have
developed at Stanford. InterViews provides a true object-oriented programming
interface that supports the composition of interactive objects (such as scroll
bars and menus), text objects (such as words and whitespace), and graphics
objects (such as circles and polygons). After a quick introduction to C++ and
InterViews basics, we will present three applications: a dialog box built from
interactive objects, a simple drawing editor using a hierarchy of graphical
objects, and a simple editor using a hierarchy of text objects.
The morning session will cover C++, InterViews basics, and a simple
application. Attendees should be familiar with C, X, and object-oriented
programming concepts. Familiarity with C++ would be helpful, but is not
required.
The afternoon session will cover graphics and text applications in detail.
Attendees who are not at the morning session should be familiar with C++ and
basic InterViews concepts.

Introduction to Programming the X Window System, Version 11
Oliver Jones, Apollo Computer, Inc.
The proposed tutorial is at the Beginning level. The X Window System is
a complex and comprehensive software package for controlling workstations.
Programmers, even those expert in computer graphics, must go up a substantial
learning curve in order to understand the issues and techniques involved in
designing and implementing application software to run on X Workstations.
This Beginning-level tutorial assumes no prior knowledge of X, and is intended
to shorten that learning curve. This tutorial is for technical professionals
who are unfamiliar with Version 11 of the X Window System. People preparing
to design and develop application software to run under X will find this
tutorial especially useful. Attendees should be generally familiar with
graphics workstation technology and networks. In addition, attendees should
be experienced with the C programming language.
The purpose of this tutorial is to help turn X novices into reasonably
competent developers of X Window System application software. The tutorial
addresses Xlib, the C language interface to X. By covering low level X
requests, the tutorial lays the conceptual foundation for understanding and
applying the various high-level human interface toolkits and user interface
management systems available as layers on X.
-------
The Andrew Toolkit (ATK): An Introduction
Andrew J. Paley and Nathaniel S. Borenstein, Carnegie Mellon University
This tutorial is intended for experienced C programmers who know nothing
about programming with the Andrew Toolkit. Some familiarity with the
concepts of object-oriented programming would be helpful, but is not
required. The tutorial will explain enough about the ATK to allow such
people to begin serious application development using the ATK, if they are so
inclined. Those with prior experience with the ATK are welcome to attend,
but should not expect extended discussion of advanced or esoteric ATK
features at this tutorial.
The Andrew Toolkit is a powerful set of tools for building complex user
interface programs in a window-system independent manner. Besides providing
many basic building blocks for such interfaces, the ATK also provides
substantial facilities for object-oriented programming, which greatly
simplify the process of constructing new interfaces. However, these
facilities require the programmer to approach his programs in ways that may
not be familiar to most C programmers. In this tutorial, we will learn how
to use the Andrew Toolkit. The primary emphasis will be on thinking like an
ATK programmer. Within this conceptual framework, we will then study the
various components, or building blocks, that the ATK offers, and how they may
be put together to form complex applications.

Display PostScript
Adam Stock and Kim Stickney, Adobe Systems
The Display PostScript System(TM) is a graphics programming environment for
interactive displays based on the PostScript(R) programming language. A
Display PostScript extension to X is being developed jointly by Adobe Systems
and Digital Equipment Corporation under the DECwindows(TM) program.
The PostScript language offers the developer a device and resolution
independent imaging model for addressing both color and black and white
displays and output devices. It offers the end-user the same imaging model on
displays that is a standard on laser printers and typesetters for true WYSIWYG
compatability.
This tutorial will cover what the application programmer needs to know to
write to the Display PostScript System. The issues include the Display
PostScript extensions, the client library interface, and pswrap, a PostScript
to C preprocessor.

Using Widgets
Dany S. Guindi, SERC Georgia Institute of Technology
This tutorial will attempt to teach the experienced C programmer how to glue
together some of the existing widgets so as to create a user interface to an
application. It will be necessary to explore both the intrinsics as well as
the different widget sets available. The tutorial will use the Athena Widget
set for examples, but will also try to cover small examples from other widget
sets. This tutorial differs from the "Writing Widgets" tutorial in that we
will NOT attempt to explain how to expand the widget set nor how to slightly
modify existing widgets!
-------
Writing Widgets (novice)
Paul Asente, DEC Western Software Lab
This is an introduction to the Xt toolkit Intrinsics for would-be widget
writers. We will go over complete implementations of three simple widgets,
label, pushbutton, and box, a simple composite widget. Classing,
subclassing, inheritance, resources, and introductory translation
management will be covered. Prerequisite: a basic familiarity with X11 and
Xlib.
-------
Writing Widgets (advanced)
Ralph Swick and Mark Ackerman, MIT Project Athena
This covers more advanced topics in the Xt toolkit Intrinsics for widget
writers. We will cover geometry management, constrained composite widgets,
resource converters, subresources, and advanced event handling.
Prerequisite: an understanding equivalent to that gained in the novice
class.
