X Athena Widgets
X Athena Widgets or Xaw is a GUI widget library for the X Window System. Developed as part of Project Athena, Xaw was written under the auspices of the MIT X Consortium as a sample widget set built on X Toolkit Intrinsics (Xt); Xt and Xaw are collectively known as the X Toolkit. Xaw has been largely superseded by more sophisticated toolkits like Motif, and later toolkits such as GTK, and Qt, but it is still maintained (by the X.Org Foundation) and is available as part of most X Window System installations. The library, like other core parts of X, is licensed under the MIT License. In a talk for USENIX, X pioneer Jim Gettys remarked that although Athena widgets were "ugly", they were often used in the period of X history that he describes as the "GUI wars", as a safe alternative to the competing Motif and Open Look OPEN LOOK (sometimes referred to as Open Look) is a graphical user interface (GUI) specification for UNIX workstations.

Widget Toolkit
A widget toolkit, widget library, GUI toolkit, or UX library is a library or a collection of libraries containing a set of graphical control elements (called ''widgets'') used to construct the graphical user interface (GUI) of programs. Most widget toolkits additionally include their own rendering engine. This engine can be specific to a certain operating system or windowing system or contain back-ends to interface with more multiple ones and also with rendering APIs such as OpenGL, OpenVG, or EGL. The look and feel of the graphical control elements can be hard-coded or decoupled, allowing the graphical control elements to be themed/ skinned. Overview Some toolkits may be used from other languages by employing language bindings. Graphical user interface builders such as e.g. Glade Interface Designer facilitate the authoring of GUIs in a WYSIWYG manner employing a user interface markup language such as in this case GtkBuilder. The GUI of a program is commonly constructed in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qt (framework)
Qt (pronounced "cute") is cross-platform software for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed. Qt is currently being developed by The Qt Company, a publicly listed company, and the Qt Project under open-source governance, involving individual developers and organizations working to advance Qt. Qt is available under both commercial licenses and open-source GPL 2.0, GPL 3.0, and LGPL 3.0 licenses. Purposes and abilities Qt is used for developing graphical user interfaces (GUIs) and multi-platform applications that run on all major desktop platforms and most mobile or embedded platforms. Most GUI programs created with Qt have a native-looking interface, in which case Qt is classified as a ''widget toolkit''. No ...

OPEN LOOK
OPEN LOOK (sometimes referred to as Open Look) is a graphical user interface (GUI) specification for UNIX workstations. It was originally defined in the late 1980s by Sun Microsystems and AT&T Corporation. History OPEN LOOK was created at a time when there was little or no standardization in Unix graphical user interfaces (GUIs); the X Window System was emerging as the likely de facto standard for Unix graphical displays, but its designers had deliberately chosen not to specify any look and feel guidelines, leaving this up to application and window manager developers. At the same time, there was increasing use of GUIs in non-UNIX operating systems: the Apple Macintosh was released in early 1984, followed by Microsoft Windows 1.0 and Amiga Workbench in 1985. As AT&T contemplated its next major revision to Unix, which would eventually become SVR4, it was believed by many that in order to remain competitive with other operating systems, Unix should have a standard GUI definitio ...

Graphical User Interface
The GUI ( "UI" by itself is still usually pronounced . or ), graphical user interface, is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based UIs, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of CLIs ( command-line interfaces), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term ''GUI'' tends not to be applied to other lower-display resolution types of interfaces, such as video games (where HUD (''head-up display'') is preferred), or not including flat screens like volumetric displays because ...

Motif (software)
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 Unix-like operating systems. The Motif look and feel is distinguished by its use of rudimentary square and chiseled three-dimensional effects for its various user interface elements. Motif is the toolkit for the Common Desktop Environment and IRIX Interactive Desktop, thus it was the standard widget toolkit for Unix. Closely related to Motif is the Motif Window Manager (MWM). After many years as proprietary software, Motif was released in 2012, as free software under the GNU Lesser General Public License (LGPL-2.1-or-later). History Motif was created by the Open Software Foundation (OSF) to be a standard graphical user interface for Unix platforms. Rather than create a new interface from scratch, OSF opened a Request For Technology (RFT) in 1988 to solicit existing technologies ...

Screenshot Of "Xman" Program
screenshot (also known as screen capture or screen grab) is a digital image that shows the contents of a computer display. A screenshot is created by the operating system or software running on the device powering the display. Additionally, screenshots can be captured by an external camera, using photography to capture contents on the screen. Screenshot techniques Digital techniques The first screenshots were created with the first interactive computers around 1960. Through the 1980s, computer operating systems did not universally have built-in functionality for capturing screenshots. Sometimes text-only screens could be dumped to a text file, but the result would only capture the content of the screen, not the appearance, nor were graphics screens preservable this way. Some systems had a BSAVE command that could be used to capture the area of memory where screen data was stored, but this required access to a BASIC prompt. Systems with composite video output could be connec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X Toolkit Intrinsics
X Toolkit Intrinsics (also known as Xt, for X toolkit) is a library that implements an API to facilitate the development of programs with a graphical user interface (GUI) for the X Window System. It can be used in the C or C++ languages. The low-level library Xlib is the client-side implementation of the X11 protocol. It communicates with an X server, but does not provide any function for implementing graphical control elements ("widgets"), such as buttons or menus. The Xt library provides support for creating widget types, but does not provide any itself. A programmer could use the Xt library to create and use a new type of widget. Xt implemented some object oriented concepts, such as inheritance (the user could make their own button by reusing code written for another type of button), events, and callbacks. Since the graphical user interface of applications typically requires a number of widget types, most developers are reluctant to write their own, and instead prefe ...

X Consortium
The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems. X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interfacethis is handled by individual programs. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence "X11") since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open-source software under the MIT License and similar permissive licenses. Purpose and abilities X is an architecture-independent system for remote graphical user interfaces and input device capabilities. Each person using a ...
