KDE (K Desktop Environment) (IPA: /ˌkeɪˌdiːˈiː/) is a free software project which aims to be a powerful system for an easy-to-use desktop environment. The goal of the project is to provide basic desktop functions and applications for daily needs as well as tools and documentation for developers to write stand-alone applications for the system. In this regard the KDE project serves as an umbrella project for many standalone applications and smaller projects that are based on KDE technology, such as KOffice, KDevelop, Amarok, K3b and many more. 4Kids Entertainment (NYSE: KDE) (commonly known as 4Kids) is an American film and television production company specializing in the acquisition, production and licensing of childrens entertainment around the world. ...

History

KDE was founded in 1996 by Matthias Ettrich, who was then a student at the Eberhard Karls University of Tübingen. At the time, he was troubled by certain aspects of the UNIX desktop. Among his qualms were that none of the applications looked, felt, or worked alike. He proposed the formation of not only a set of applications, but rather a desktop environment, in which users could expect things to look, feel, and work consistently. He also wanted to make this desktop easy to use; one of his complaints with desktop applications of the time was that his girlfriend could not use them. His initial Usenet post spurred a lot of interest, and the KDE project was born.[1] The name KDE was intended as a word play on the existing Common Desktop Environment, available for Unix systems. CDE was an X11-based user environment jointly developed by HP, IBM, and Sun, through the X/Open Company, with an interface and productivity tools based on the Motif graphical widget toolkit. It was supposed to be an intuitively easy-to-use desktop computer environment.[2] The K was originally suggested to stand for "Kool", but it was quickly decided that the K should stand for nothing in particular.[3] Additionally, one of the tips in certain versions of KDE 3 incorrectly states that the K currently is just meant to be the letter before L in the Latin alphabet, the first letter in the word Linux (which is where KDE is usually run).[4] Matthias Ettrich (born June 14, 1972 in Bietigheim, southern Germany) is the computer scientist who founded the KDE project in 1996, when he proposed a consistent, nice looking free desktop-environment [sic] [1] for UNIX using the Qt GUI toolkit on USENET in 1996. ...

Matthias chose to use the Qt toolkit for the KDE project. Other programmers quickly started developing KDE/Qt applications, and by early 1997, large and complex applications were being released. At the time, Qt did not use a free software license and members of the GNU project became concerned about the use of such a toolkit for building a free software desktop and applications. Notably, KDE was removed from Debian because the project interpreted the GPL as not allowing KDE to be linked to Qt. Two projects were started: "Harmony", to create a Free replacement for the Qt libraries, and the GNOME project to create a new desktop without Qt and built entirely on top of free software. For other uses, see Qt. ... Free software is software which grants recipients the freedom to modify and redistribute the software. ...

This article is about the mythical creature. ...


In November 1998, the Qt toolkit was licensed under the free/open source Q Public License (QPL). This same year the KDE Free Qt foundation[5] was created which guarantees that Qt would fall under a variant of the very liberal BSD license should Trolltech cease to exist or no free/open source version of Qt be released during 12 months. But debate continued about compatibility with the GNU General Public License (GPL). In September 2000, Trolltech made the Unix version of the Qt libraries available under the GPL, in addition to the QPL, which has eliminated the concerns of the Free Software Foundation. Starting with the release of Qt 4.0, it is available as free software for the Unix, Mac and Windows platforms, indicating that the next major version of KDE applications and libraries will have native support on these platforms.

Organization of the KDE project

Like many free/open source software projects, KDE is primarily a volunteer effort, although various companies, such as Novell (in the form of SuSE), Trolltech, and Mandriva employ developers to work on the project. Since a large number of individuals contribute to KDE in various ways (e.g. code, translation, artwork), organization of such a project is complex. Most problems are discussed on a number of different mailing lists. Novell Inc. ...

A mailing list is a collection of names and addresses used by an individual or an organization to send material to multiple recipients. ...


Important decisions, such as release dates and inclusion of new applications, are made on the kde-core-devel list by the so-called core developers. These are developers who have made significant contributions to KDE over a long period of time. Decisions are not made by a formal voting process, but by discussion on the mailing lists. In most cases this seems to work well, and major discussions (such as the question of whether the KDE 2 API should be broken in favour of KDE 3) are rare. This article does not cite any references or sources. ... API and Api redirect here. ...


While developers and users are now located all over the world, the project retains a strong base in Germany. The web servers are located at the universities of Tübingen and Kaiserslautern, a German non-profit organization (KDE e.V.) owns the trademark on "KDE", and KDE conferences often take place in Germany. Tübingen, Neckar front Tübingen, a traditional university town of Baden-Württemberg, Germany, is situated 20 miles southwest of Stuttgart, on a ridge between the River Neckar and the Ammer. ...

As the project history below shows, the KDE team releases new versions on a frequent basis. It is rare that a release is delayed for more than one or two weeks. An exception was KDE 3.1, which was delayed for more than a month because of a number of security issues in the code base.

There are two main types of releases, major releases and minor releases.


Major releases

There have been 11 major releases so far: 1.0, 1.1, 2.0, 2.1, 2.2, 3.0, 3.1, 3.2, 3.3, 3.4 and 3.5. The current major release is 3.5, which arrived on November 29, 2005. The next major release will be KDE 4.0, which has been scheduled for release on December 11, 2007 (see the KDE 4 roadmap). KDE 4 will be based on Qt 4.x, encompassing some major changes to the desktop. is the 333rd day of the year (334th in leap years) in the Gregorian calendar. ... Year 2005 (MMV) was a common year starting on Saturday (link displays full calendar) of the Gregorian calendar. ... KDE 4 is the next series of the K Desktop Environment software. ...

Year 2007 (MMVII) is the current year, a common year starting on Monday of the Gregorian calendar and the AD/CE era in the 21st century. ...


The KDE X.0 releases are special, as they are allowed to break both binary and source-compatibility with the predecessor, or to put it differently, all following releases (X.1, X.2, …) will guarantee binary (ABI) and source compatibility (API). This means, for instance, that software that was developed for KDE 3.0 will work on all (future) KDE 3 releases, in contrast to an application that was developed for KDE 2, which is not guaranteed to be able to make use of the KDE 3 libraries. In computing, a device (usually a computer processor) that can run the same source code intended to be compiled and run on another device is said to be source-compatible. ... In computer software, an application binary interface (ABI) describes the low-level interface between an application program and the operating system, between an application and its libraries, or between component parts of the application. ... API and Api redirect here. ...


The changes between KDE 1 and KDE 2 series were large and many, while the API changes between KDE 2 and KDE 3 were comparatively minor, meaning that applications could be more easily ported to the new architecture. Up to now the KDE major version numbers follow the Qt release cycle.


Besides the special X.0 releases, a major release will allow new features. Minor releases in general don't allow new features although some releases in the 3.5.x line have had minor enhancements.


As soon as a major release is ready and announced, work on the next major release starts. A major release needs several months to be finished and many bugs that are fixed during this time are backported to the stable branch, meaning that these fixes are incorporated into the last stable release. Backporting is the action of taking a certain software modification (patch) and applying it to an older version of the software than it was initially created for. ...


Minor releases

A minor KDE release has three version numbers, e.g. KDE 1.1.1, and a focus on fixing bugs, minor glitches and making small usability improvements, as opposed to adding new features. For minor releases, a shortened release schedule is used. A maintenance release (also minor release) is a release of a product that does not add new features or content. ...


KDE 4

Some of the planned features are:[8][9]

  • Faster and more memory efficient, due to the greater speed and efficiency of Qt 4 and increased efficiency in the KDE libraries themselves.
  • Reorganized and cleaned up core kdelibs API and rewritten human interface guidelines.
  • A new default icon theme and visual guidelines, developed by the Oxygen Project, which will make extensive use of SVG.
  • A completely redesigned desktop and panels collectively called Plasma which will integrate Kicker, KDesktop, and SuperKaramba and is intended to update the decades-old desktop metaphor which defines the modern computing experience.
  • 3D effects in the KWin window manager
  • Streamlined file management and web browsing interfaces in Konqueror.
  • A standard scripting system centered around ECMAScript (also known as JavaScript) or Kross which is a language-independent solution developed and used in KOffice. It now supports Python and Ruby, but more are to come.
  • A new multimedia interface (Phonon), making KDE independent of any one specific media framework.
  • An API for network and portable devices (Solid)
  • A new communication framework (Decibel)
  • A metadata and search framework, probably named Tenor. It will incorporate Strigi as a full-text file indexing service, and Nepomuk with KDE integration.
  • A new default file manager (Dolphin)
  • Microsoft Windows and Mac OS X support by KDE libraries so that KDE applications will more easily be ported to these operating systems[10]
  • A new spell checking program called Sonnet with automatic language detection. It will replace kspell to mark misspellings in text input fields in KDE-based applications. Advantages over kspell are the automatic language detection and the ability to work even if several languages are mixed in one document.

Architecture

KDE is built with Trolltech's Qt toolkit which runs on most Unix and Unix-like systems, Mac OS X and Microsoft Windows. All releases of KDE 3 are built upon Qt 3, which was only released under the GPL for Linux and Unix-like operating systems, including Mac OS X. For that reason, KDE 3 is only available on Windows through ports involving an X server. Trolltech (formerly known as Quasar Technologies) is a computer software company from Oslo, Norway. ...

KDE 4 will be based on Qt 4 which is also released under the GPL for Windows and Mac OS X. Therefore KDE 4 applications can run natively on these operating systems as well.

Naming convention

Most KDE applications have a K in the name, mostly as an initial letter and capitalized. However, there are notable exceptions like kynaptic, whose K is not capitalized, Gwenview, which does not have a K in the name at all, and Amarok which formerly had its final k capitalized. The K in many KDE applications is obtained by spelling a word which originally begins with C or Q differently, for example Konsole (which, incidentally, is correct spelling in German) and Kuickshow. Also, some just prefix a commonly used word with a K, for instance KOffice. A screenshot of Synaptic. ... Gwenview is an image viewer for the KDE desktop environment. ... Amarok is a free software music player for Linux and other varieties of Unix. ... Konsole is a free terminal emulator which is part of KDE. It is a complete rewrite, as opposed to many other terminal emulators that are derivatives of xterm or rxvt. ... Kuickshow is an image viewer and slideshow program for the KDE operating-system. ... KOffice is an office suite for the K Desktop Environment (KDE). ...


Licensing issues

Qt, to which native graphical KDE applications link for their graphical widgets, is free software, dual-licensed under the GNU GPL and QPL licenses. TrollTech also sell licenses for developing proprietary software. When using the free versions, programs which link to Qt must be released as FOSS (under the GPL or another license permitted by the QPL, such as the BSD or LGPL for example). After the release of Qt under the GPL, the controversy over licensing with the Free Software Foundation ended. For other uses, see Qt. ... In computer programming, widget toolkits (or GUI toolkits) are sets of basic building units for graphical user interfaces. ... // Licenses are granted by copyright holders to grant exceptions of copyright law to users for a work. ... GPL redirects here. ... The Q Public License (QPL) is a copyleft license created by Trolltech for its free edition of the Qt toolkit. ... It has been suggested that closed source be merged into this article or section. ... Clockwise from top: The logo of the GNU Project, the Linux kernel mascot Tux, and the BSD Daemon Free software is software that can be used, studied, and modified without restriction, and which can be copied and redistributed in modified or unmodified form either without restriction, or with restrictions only...


Some developers of proprietary/closed source software argue that paying for a license, similar to the relatively expensive development tools of other systems, removes most of the financial incentive for writing proprietary/closed source, native graphical KDE applications. However, it is not necessary to use Qt or the KDE libraries to write software which integrates well with the KDE desktop. Software using any other toolkit, following the freedesktop.org standards or using KDE facilities such as KPrinter and KDialog can integrate nicely with the KDE desktop (both KPrinter and KDialog link to Qt, and are under the GPL), however the widgets will not have the exact behavior of Qt widgets. Additional integration efforts are being discussed in the Portland Free Desktop initiative,[21] and are planned for KDE 4. The text below is generated by a template, which has been proposed for deletion. ... freedesktop. ... The Portland Project is an initiative taken to establish a greater Linux foothold in the desktop market. ...


Some other free/open source desktop platforms (such as GNOME, Xfce and EDE) use toolkits licensed under the LGPL. The LGPL permits proprietary/closed source applications to link to libraries licensed under the LGPL, with some restrictions: the Section 6 of the LGPL v2.1 prohibits linking to software with a license that restricts reverse-engineering and modification of the work for the customer's own use.[22] The proprietary Qt license which TrollTech sells does not carry these restrictions. This article is about the mythical creature. ... Xfce ([1]) is a free software desktop environment for Unix and other Unix-like platforms, such as Linux, Solaris and BSD. Its configuration is entirely mouse-driven and the configuration files are hidden from the casual user. ... Ede is a Hungarian given name which can be traced back to Edward. ... In computer programming, widget toolkits (or GUI toolkits) are sets of basic building units for graphical user interfaces. ... GNU logo The GNU Lesser General Public License (formerly the GNU Library General Public License) is an FSF approved Free Software license designed as a compromise between the GNU General Public License and simple permissive licenses such as the BSD license and the MIT License. ... Proprietary software is software with restrictions on using, copying and modifying as enforced by the proprietor. ...


Usability

KDE aims to make easy-to-use programs without sacrificing features. KDE's Usability page states its goal as: "Working within the existing design goals of a system, usability efforts aim to make the implementations of these designs easier to use, faster to learn, more consistent and obvious, and generally more ergonomic for their target audience." [23] To improve the user interface, work has gone into reducing visual complexity for versions 3.2 to 3.5. The most promising effort is the close work with the OpenUsability Project. One of the major goals of KDE 4.0 is to identify further areas that are lacking from a usability perspective and address these concerns. In particular, new human interface guidelines are being developed for KDE 4.0.


KDE strives to make otherwise onerous or difficult tasks easier, such as adding printers (local or networked), setting up 802.11 Wireless security settings (such as WEP), and installing new fonts and window decorations. Third-party web sites LinuxPrinting, art4linux.org and KDE-Look support KDE through adding devices or customizing the environment's look and feel. IEEE 802. ... Wired Equivalent Privacy or Wireless Encryption Protocol (WEP) is a scheme to secure IEEE 802. ...


The KDE interface has been criticised for being too complex and including too many configurable options. However, a usability report evaluating a customized version of KDE 3.1 showed, as early as 2003, that Windows users quickly became familiar with KDE, enjoyed it and were able to accomplish the proposed task as quickly as with Windows XP.[24] Windows XP is a line of operating systems developed by Microsoft for use on general-purpose computer systems, including home and business desktops, notebook computers, and media centers. ...


Sponsorship

The KDE project and related events are frequently sponsored by individuals, universities, and businesses.[25] This article does not cite any references or sources. ...


On 15 October 2006, it was announced that Mark Shuttleworth became the first patron of KDE, the highest level of sponsorship available.[26] On 2007-07-07, it was announced that Intel Corporation and Novell became patrons of KDE.[27] is the 288th day of the year (289th in leap years) in the Gregorian calendar. ... Year 2006 (MMVI) was a common year starting on Sunday of the Gregorian calendar. ... Mark Richard Shuttleworth (born 18 September 1973) is a South African entrepreneur who was the second self-funded space tourist and first African national in space. ... Generally, patronage is the act of supporting or favoring some person, group, or institution. ...

Using KDE

Home (267 words)
KDE on Cygwin is the port of Qt and KDE to Windows using Cygwin, the POSIX emulation layer for Windows, and the Cygwin XFree86 server.
We think that KDE is a great desktop and has the opportunity to be a big player in the 'desktop environment' area.
Currently Qt 1.45, 2.3.1, 3.0.4, 3.1.1, 3.2.3 and KDE 1.45, 2.2.2, 3.1.1 and 3.1.4 have been ported and are of beta quality.
KDE - definition of KDE in Encyclopedia (1449 words)
KDE (K Desktop Environment) is a free desktop environment and development platform built with Trolltech's Qt toolkit.
KDE was founded in 1996 by Matthias Ettrich, who was then a student at the University of Tübingen.
Like many open source/free software projects, KDE is primarily a volunteer effort, although various companies, such as Novell (in the form of SuSE), Trolltech, and MandrakeSoft employ developers to work on the project.
