John Kenneth Ousterhout is a professor of computer science at Stanford University. He founded Electric Cloud with John Graham-Cumming. Ousterhout was a professor of computer science at University of California, Berkeley where he created the Tcl scripting language and the Tk platform-independent widget toolkit, and proposed the idea of coscheduling. Ousterhout led the research group that designed the experimental Sprite operating system and the first log-structured file system. Ousterhout also led the team that developed the Magic VLSI computer-aided design (CAD) program.
Fast Light Toolkit (FLTK) is a cross-platform widget library for graphical user interfaces (GUIs), developed by Bill Spitzak and others. Made to accommodate 3D graphics programming, it has an interface to OpenGL, but it is also suitable for general GUI programming.
GNU Ubiquitous Intelligent Language for Extensions is the preferred extension language system for the GNU Project and features an implementation of the programming language Scheme. Its first version was released in 1993. In addition to large parts of Scheme standards, Guile Scheme includes modularized extensions for many different programming tasks.
Widget is an animated children's television series created by Voltron creator Peter Keefe, directed and produced by Tom Burton of Zodiac Entertainment, which debuted in syndication on September 29, 1990. The series ran for two seasons; in the first season (1990), it aired once a week, and in the second season (1991), the series expanded to weekdays. The show featured environmentalist themes and was recognized by the National Education Association as recommended viewing for children.
Shane's Chess Information Database (Scid) is a free and open source UNIX, Windows, Linux, and Mac application for viewing and maintaining large databases of chess games. It has features comparable to popular commercial chess software. Scid is written in Tcl/Tk and C++.
The Visualization Toolkit (VTK) is an open-source software system for 3D computer graphics, image processing and scientific visualization.
Sakura HyperMedia Desktop is an open source desktop environment and knowledge navigator for Unix. It is written in scripting languages such as Python and Tcl, and therefore runs on a variety of platforms. The Sakura HyperMedia Desktop Project lists the main features as follows:
Tkinter is a Python binding to the Tk GUI toolkit. It is the standard Python interface to the Tk GUI toolkit, and is Python's de facto standard GUI. Tkinter is included with standard Linux, Microsoft Windows and macOS installs of Python.
ns is a name for a series of discrete event network simulators, specifically ns-1, ns-2, and ns-3. All are discrete-event computer network simulators, primarily used in research and teaching.
Tkhtml is a discontinued open-source browser engine written in C using the Tk widget toolkit. It was used primarily by the Html Viewer 3 (Hv3) minimalist web browser.
incr Tcl is a set of object-oriented extensions for the Tcl programming language. It is widely used among the Tcl community, and is generally regarded as industrial strength. Its name is a pun on "C++". Itcl implementations exist as both a package that may be dynamically loaded by a Tcl application, as well as an independent standalone language with its own interpreter.
Tk is a cross-platform widget toolkit that provides a library of basic elements of GUI widgets for building a graphical user interface (GUI) in many programming languages. It is free and open-source software released under a BSD-style software license.
wish is a Tcl interpreter extended with Tk commands, available for Unix-like operating systems supporting the X Window System, as well as macOS, Microsoft Windows, and Android. It provides developers the ability to create GUI widgets using the Tk toolkit and the Tcl programming language.
Tkabber is a GPL instant messaging client for the XMPP protocol which uses the Tk toolkit for the GUI. It runs on anything to which Tcl/Tk is ported: almost any X-based system, Microsoft Windows, and Mac OS X.
tkWWW is an early, now discontinued web browser and WYSIWYG HTML editor written by Joseph Wang at MIT as part of Project Athena and the Globewide Network Academy project. The browser was based on the Tcl language and the Tk (toolkit) extension but did not achieve broad user-acceptance or market share, although it was included in many Linux distributions by default. Joseph Wang wanted tkWWW to become a replacement for r r n and to become a "swiss army knife" of networked computing.
Tcl is a high-level, general-purpose, interpreted, dynamic programming language. It was designed with the goal of being very simple but powerful. Tcl casts everything into the mold of a command, even programming constructs like variable assignment and procedure definition. Tcl supports multiple programming paradigms, including object-oriented, imperative, functional, and procedural styles.
In computer science and visualization, a canvas is a container that holds various drawing elements. It takes its name from the canvas used in visual arts. It is sometimes called a scene graph because it arranges the logical representation of a user interface or graphical scene. Some implementations also define the spatial representation and allow the user to interact with the elements via a graphical user interface.
