Motif (widget toolkit)
Encyclopedia
In computing, Motif refers to both a graphical user interface
(GUI) specification and the widget toolkit
for building applications that follow that specification under the X Window System
on Unix
and other POSIX
-compliant systems. It emerged in the 1980s as Unix workstation
s were on the rise, as a competitor to the OPEN LOOK
GUI. It is now the basic building block of the Common Desktop Environment
.
The IEEE 1295 standard
defines the Motif API
. As of version 2.1 Motif supports Unicode
, which has made it widely used in several multilingual environments.
The Motif look and feel is distinguished by its use of square, chiseled, three-dimensional effects for its various user interface elements — menus, buttons, sliders, text boxes, and the like. Motif's operation was designed to correspond closely with the then-familiar Microsoft Windows
and OS/2's Presentation Manager
interfaces, and Microsoft
played a key role in designing the original style guide.
Motif was created by the Open Software Foundation
(and was sometimes even called OSF/Motif), which has now been subsumed by The Open Group
.
There are a few implementation
s of the Motif API. Motif the toolkit is the first. There is also Open Motif
which is a release of the "original" Motif under more liberal licensing terms. Finally, the LessTif
project aims to implement the API under the LGPL license.
Graphical user interface
In computing, a graphical user interface is a type of user interface that allows users to interact with electronic devices with images rather than text commands.
