KDE Software Compilation 4
KDE Software Compilation 4 (KDE SC 4) was the only series of the so-called KDE Software Compilation (KDE SC), first released in January 2008. The final release was version 4.14.3 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 (software), Qt 4. It contained a new multimedia API called Phonon (KDE), Phonon, a device integration framework called Solid (KDE), Solid, and a new style guide and default icon set called Oxygen Project, Oxygen. It also included a new, unified desktop and panel user interface called KDE Plasma Workspaces, Plasma, which sup ...

ThreadWeaver
ThreadWeaver is a system library initially developed for KDE Software Compilation 4 and later refactored for KDE Frameworks 5. ThreadWeaver allows developers to easily take advantage of multi-core processors and multithreading. In ThreadWeaver the workload is divided into individual jobs, then relationship between jobs (what order they should be completed or which has a higher priority); from that ThreadWeaver will work out the most efficient way to execute them. Krita Krita ( ) is a free and open-source software, free and open-source raster graphics editor designed primarily for digital art and 2D animation. Originally created for Linux, the software also runs on Windows, macOS, Haiku (operating system), Hai ... has implemented visual filter previews using ThreadWeaver to prevent GUI lockups.

KHTML
KHTML is a discontinued browser engine that was developed by the KDE project. It originated as the engine of the Konqueror browser in the late 1990s, but active development ceased in 2016. It was officially discontinued in 2023. Built on the KParts framework and written in C++, KHTML had relatively good support for Web standards during its prime. Engines forked from KHTML are used by most of the browsers that are widely used today, including WebKit (Safari) and Blink (Google Chrome, Chromium, Microsoft Edge, Opera, Vivaldi and Brave). History Origins KHTML was preceded by an earlier engine called ''khtmlw'' or ''the KDE HTML Widget'', developed by Torben Weis and Martin Jones, which implemented support for HTML 3.2, HTTP 1.0, and HTML frames, but not the DOM, CSS, or JavaScript. KHTML itself came into existence on November 4, 1998, as a fork of the khtmlw library, with some slight refactoring and the addition of Unicode support and changes to support the move to Qt ...

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 ...

Kross (KDE)
Kross is a scripting framework for KDE Frameworks. Kross was originally designed for use in KOffice but eventually became the official scripting framework in KDE Software Compilation 4 before being dropped in Frameworks 6. The Kross scripting framework is not a scripting language itself; it is an interface for developers to support scripting by specifying functions, which the user will then script using a language that Kross supports. It currently supports Python, Ruby, JavaScript, and the Falcon Programming Language. Support for other languages can be added with modules. Comparison with other scripting frameworks SWIG: Simplified Wrapper and Interface Generator * Kross currently has fewer supported scripting languages. * Kross is built on top of Qt/KDE. This allows access to Qt/KDE things without needing extra effort to wrap them. * Applications supporting Kross do not require as much code as to support SWIG. * With SWIG, the set of supported scripting languages is determined at t ...

KNewStuff
KDE Frameworks is a collection of libraries and software frameworks readily available to any Qt-based software stacks or applications on multiple operating systems. Featuring frequently needed functionality solutions like hardware integration, file format support, additional graphical control elements, plotting functions, and spell checking, the collection serves as the technological foundation for KDE Plasma and KDE Gear. It is distributed under the GNU Lesser General Public License (LGPL). Overview KDE Frameworks is based on Qt, which enables a more widespread use of QML, a simpler JavaScript-based declarative programming language, for the design of user interfaces. The graphics rendering engine used by QML allows for more fluid user interfaces across different devices. Since the split of the KDE Software Compilation into KDE Frameworks 5, KDE Plasma 5 and KDE Applications, each sub-project can pick its own development pace.

Desktop Communication Protocol
Desktop Communication Protocol (DCOP) was an inter-process communication (IPC) daemon by KDE used in K Desktop Environment 3. The design goal for the protocol was to allow applications to interoperate, and share complex tasks. Essentially, DCOP was a ‘remote control’ system, which allowed applications or scripts to enlist the help of other applications. DCOP is built on top of the X11 Inter-Client Exchange protocol. DCOP continues to be used by the K Desktop Environment 3-fork Trinity Desktop Environment. DCOP was replaced by D-Bus, a message bus system heavily influenced by the DCOP and standardized by freedesktop.org, in KDE Software Compilation 4 and later. DCOP model DCOP implements the client–server model, where each application using DCOP is a client and communicates with other clients through the DCOP server. DCOP server functions like a traffic director, dispatching messages/calls to the proper destinations. All clients are peers of each other. Two types of acti ...

KDE Brand Map
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 enable collaborative work on its projects. Its products include the KDE Plasma graphical shell, KDE Frameworks, and the KDE Gear range of applications including Kate, digiKam, and Krita. Many KDE applications are cross-platform and can run on Unix and Unix-like operating systems, Microsoft Windows, and Android. KDE is legally represented by KDE e.V. based in Germany, which also owns the KDE trademarks and funds the project. Origins KDE 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 enviro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Kiosk (KDE)
Historically, a kiosk () was a small garden pavilion open on some or all sides common in Iran, Persia, the Indian subcontinent, and in the Ottoman Empire from the 13th century onward. Today, several examples of this type of kiosk still exist in and around the Topkapı Palace in Istanbul, and they can be seen in Balkan countries. The word is used in English-speaking countries for small booths offering goods and services. In Australia they usually offer food service. Freestanding computer terminals dispensing information are called interactive kiosks. Etymology Etymological data points to the Middle Persian word ''kōšk'' 'palace, portico' as the origin, via Turkish language, Turkish ''köşk'' 'pavilion' and French ''kiosque'' or Italian ''chiosco''. History and origins A kiosk is an open summer-house or pavilion usually having its roof supported by pillars with screened or totally open walls. As a building type, it was first introduced by the Sasanian Empire, Sasanid and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
