KDE SC 4
KDE Software Compilation 4 (KDE SC 4) was the only series of the so-called KDE Software Compilation (short: KDE SC), first released in January 2008 and the last release being 4.14.3 released in November 2014. It was the follow-up to K Desktop Environment 3. Following KDE SC 4, the compilation was broken up into basic framework libraries, desktop environment and applications, which are termed KDE Frameworks 5, KDE Plasma 5 and KDE Applications, respectively. Major releases (4.x) were released every six months, while minor bugfix releases (4.x.y) were released monthly. The series included updates to several of the KDE Platform's core components, notably a port to Qt 4. It contained a new multimedia API, called Phonon, a device integration framework called Solid and a new style guide and default icon set called Oxygen. It also included a new, unified desktop and panel user interface called Plasma, which supported desktop widgets, replacing K Desktop Environment 3's separate ...

KDE Oxygen Logo
KDE is an international free software community that develops free and open-source software. As a central development hub, it provides tools and resources that allow collaborative work on this kind of software. Well-known products include the Plasma Desktop (the default desktop environment on many Linux distributions), KDE Frameworks, and a range of cross-platform applications such as Amarok, digiKam, and Krita that are designed to run on Unix and Unix-like operating systems, Microsoft Windows, and Android. Origins KDE (back then called the ''K(ool) Desktop Environment'') was founded in 1996 by Matthias Ettrich, a student at the University of Tübingen. At the time, he was troubled by certain aspects of the Unix desktop. Among his concerns was that none of the applications looked or behaved alike. In his opinion, desktop applications of the time were too complicated for end users. In order to solve the issue, he proposed the creation of a desktop environment in which ...

Phonon (KDE)
Phonon is the multimedia API provided by KDE and is the standard abstraction for handling multimedia streams within KDE software and also used by several Qt applications. Phonon was originally created to allow KDE and Qt software to be independent of any single multimedia framework such as GStreamer or xine and to provide a stable API for a major version's lifetime. It was done for various reasons: to create a simple KDE/ Qt style multimedia API, to better support native multimedia frameworks on Windows and macOS, and to fix problems of frameworks becoming unmaintained or having API or ABI instability. For example, a file can be played in four lines of C++ code, compared to 30 lines in the old audio framework for KDE (aRts) Phonon::MediaObject* media = new Phonon::MediaObject(this); createPath(media, new Phonon::AudioOutput(Phonon::MusicCategory, this)); media->setCurrentSource(QUrl("/tmp/example.wav")); media->play(); Phonon is not designed to have every conceivable multime ...

KOffice
KOffice is a free and open source office and graphics suite developed by KDE for Unix-like and Windows systems. KOffice contains a word processor (KWord), a spreadsheet ( KSpread), a presentation program (KPresenter), and a number of other components that varied over the course of its development. KOffice was superseded by Calligra Suite in KDE. The KDE3 version is maintained by the Trinity Desktop project. After development began in 1997, two major stable releases of KOffice were published: Version 1.0 in 2000 and 2.0 in 2009. Following internal conflicts, the majority of KOffice developers split off in 2010 – resulting in the creation of Calligra Suite. Two years later, in September 2012, the KOffice.org website went offline. It now redirects to Calligra.org. History First generation Initial work on KOffice development began in 1997, by Reginald Stadlbauer with KPresenter, followed by KWord in 1998. In 1999, KOffice was cited in testimony in the ''United States v. M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extragear
The KDE Gear (also known as the KDE Applications Bundle or KDE Applications) is a set of applications and supporting libraries that are developed by the KDE community, primarily used on Linux-based operating systems but mostly multiplatform, and released on a common release schedule. The bundle is composed of over 100 applications. Examples of prominent applications in the bundle include the file manager Dolphin, document viewer Okular, text editor Kate, archiving tool Ark and terminal emulator Konsole. Previously the KDE Applications Bundle was part of the KDE Software Compilation. Extragear Software that is not part of the official KDE Applications bundle can be found in the "Extragear" section. They release on their own schedule and feature their own versioning numbers. There are many standalone applications like KTorrent, Krita or Amarok that are mostly designed to be portable between operating systems and deployable independent of a particular workspace or desktop env ...

Google Summer Of Code
The Google Summer of Code, often abbreviated to GSoC, is an international annual program in which Google awards stipends to contributors who successfully complete a free and open-source software coding project during the summer. , the program is open to anyone aged 18 or over, no longer just students and recent graduates. It was first held from May to August 2005. Participants get paid to write software, with the amount of their stipend depending on the purchasing power parity of the country where they are located. Project ideas are listed by host organizations involved in open-source software development, though students can also propose their own project ideas. The idea for the Summer of Code came directly from Google's founders, Sergey Brin and Larry Page. From 2007 until 2009 Leslie Hawthorn, who has been involved in the project since 2006, was the program manager. From 2010 until 2015, Carol Smith was the program manager. In 2016, Stephanie Taylor took over management of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LXDE
LXDE (abbreviation for Lightweight X11 Desktop Environment) is a free desktop environment with comparatively low resource requirements. This makes it especially suitable for use on older or resource-constrained personal computers such as netbooks or system on a chip computers. Overview LXDE is written in the C programming language, using the GTK 2 toolkit, and runs on Unix and other POSIX-compliant platforms, such as Linux and BSDs. The LXDE project aims to provide a fast and energy-efficient desktop environment. In 2010, tests suggested that LXDE 0.5 had the lowest memory-usage of the four most-popular desktop environments of the time (the others being GNOME 2.29, KDE Plasma Desktop 4.4, and Xfce 4.6), and that it consumed less energy, which suggests mobile computers with Linux distributions running LXDE 0.5 drained their batteries at a slower pace than those with other desktop environments. LXDE uses rolling releases for its individual components (or for groups of comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNOME
A gnome is a mythological creature and diminutive spirit in Renaissance magic and alchemy, first introduced by Paracelsus in the 16th century and later adopted by more recent authors including those of modern fantasy literature. Its characteristics have been reinterpreted to suit the needs of various story tellers, but it is typically said to be a small humanoid that lives underground. Diminutive statues of gnomes introduced as lawn ornaments during the 19th century grew in popularity during the 20th century and came to be known as garden gnomes. History Origins The word comes from Renaissance Latin ''gnomus'', which first appears in ''A Book on Nymphs, Sylphs, Pygmies, and Salamanders, and on the Other Spirits'' by Paracelsus, published posthumously in Nysa in 1566 (and again in the Johannes Huser edition of 1589–1591 from an autograph by Paracelsus). The term may be an original invention of Paracelsus, possibly deriving the term from Latin ''gēnomos'' (itself represen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Widget Engine
A software widget is a relatively simple and easy-to-use software application or component made for one or more different software platforms. A desk accessory or applet is an example of a simple, stand-alone user interface, in contrast with a more complex application such as a spreadsheet or word processor. These widgets are typical examples of transient and auxiliary applications that don't monopolize the user's attention. On the other hand, graphical control elements (GUI "widgets") are examples of reusable modular components that are used together to build a more complex application, allowing programmers to build user interfaces by combining simple, smaller components. Classification Because the term, and the coding practice, has been extant since at least the 1980s, it has been applied in a number of contexts. Primary types A Graphical control element (GUI widget) is part of a graphical user interface (GUI) that allows a computer user to control and change the appearance ...
