Glossaire
Accueil >> Introduction >> Glossaire
Cette page vise à fournir une référence non-technique, ainsi que des liens pour plus d'informations ou des démonstrations.
Un aperçu général
Un guide visuel de KDE 4.0 et une vidéo de KDE 4.1 donneront un excellent aperçu de KDE Software Compilation 4 dans ses premiers jours.
Le glossaire suivant est destiné à vous aider à trouver votre chemin à travers les brumes des nouveaux noms et des nouveaux concepts. Dans certains cas, vous pouvez trouver un lien à partir d'un composant KDE 3 vers son équivalent dans le contexte des logiciels KDE SC 4.
Activités
- Les activités sont des ensembles de 'widgets' Plasma qui ont leur propre fond d'écran. Un peu comme les Bureaux Virtuels, mais pas tout à fait.
- Par exemple vous avez une "activité de travail" avec des lecteurs de flux RSS, une note pour votre TODO liste, une Vue de Dossier contenant les fichiers relatifs à votre travail, et un subtile fond d'écran.
- À côté, vous avez une "activité temps libre", avec des photos de votre famille et vos chiens, des flux rss de vos blogs favoris, une Vue de Dossier montrant votre collection de films, une applet Twitter et bien sûr ce fond d'écran d'Iron Maiden que vous aimez depuis le début des années 80.
- À 17h00 pétantes, vous passez de l'"activité de travail" à l'"activité de temps libre".

Akonadi
- Le mécanisme d'accès aux stockages des données de toutes les données des PIM (Personal Information Manager - Gestionnaire d'Informations Personnelles) dans KDE SC 4. Un seul système de stockage et de recherche permet une efficacité et une extensibilité impossible sous KDE 3, où chaque élément PIM avait son propre système. Notez que l'utilisation d'Akonadi ne change pas les formats de stockages de données (vcard, iCalendar, mbox, maildir, etc.) - il fournit simplement un nouveau moyen d'accéder et de mettre à jour les données.
- Les principales raisons du design et développement d'Akonadi sont de nature technique, par exemple avoir une unique façon d'accéder aux données PIM (contacts, calendriers, emails, etc.) depuis différentes applications (kmail, kword, etc.), en éliminant ainsi le besoin d'écrire du code similaire ici et là.
- Un autre but est de séparer les applications avec interface graphique comme kmail des accès directs aux ressources externes comme les serveurs de courrier électronique - ce qui était une des raisons principales des rapports de bogues/souhaits en relation avec la performance/temps de réponse dans le passé.

aRts
- Le framework de son dans KDE 2 et 3. Sa nature mono-tâche causait des problèmes lorsque deux sources de son se rencontraient. Dans l'espace de travail Plasma il est remplacé par Phonon
- Plus information:
Conteneur
- Un conteneur est un groupement haut-niveau de widgets. Chaque Conteneur gère la mise en page et les données de configuration de l'ensemble de ses widgets indépendamment des autres Conteneurs.
- Le résultat final est que vous pouvez grouper des widgets dans un Conteneur en fonction de l'importance de votre méthode de travail et non pas un groupement en dossiers.
D-Bus
- An inter-service messaging system. Developed by RedHat, it was heavily influenced by KDE3's DCOP, which it supercedes.
- More info:
Dolphin
- The default file manager in KDE SC 4. It has a side panel (Places), but navigation is mainly by the breadcrumb trail above the main window. Split windows are possible, and views can be applied to individual windows. Mounting and umounting USB devices can be done in the side-panel. Other directories can be added to the Places panel. A Tree view is also possible.
- More info:
Extender
- Extenders are a special kind of popup that can grow out of a Plasma panel for example. Extenders have detachable parts. Extenders are a new concept that arrived in Plasma for KDE 4.2. Notifications already use this system. This enables, for example, a user to drag a notification of a download or file copy job, onto his or her desktop and keep track of it there. The same can be done for other kinds of notifications, too.
- More info:
Flake
- Flake is a programming library to be used in KOffice2. Functionally, it provides Shapes to display content and Tools to manipulate content. Shapes can be zoomed or rotated and can be grouped to work as a single Shape, around which text flow is possible.
- More info:
Get Hot New Stuff
- Get Hot New Stuff (GHNS) is an open standard that makes it easy for users to download and install various extensions for their applications. Our implementation of GHNS is used by Plasma (for example to get new desktop themes), and by many applications and widgets.
- More info:
Home Directory
- That's the place in your system where all your files are kept. You can write your files outside of this folder, but all applications are configured to propose this folder as place to write your files to. It is easier when you keep your things here.
- More info:
KControl
- KDE Control Center, for setting global preferences in KDE 3. Replaced by the System Settings interface in KDE SC 4.
KDOM
- A KPart module making KHTML DOM (Document Object Model) rendering capabilities available to all applications. KSVG2 is built on KDOM for KDE SC 4.
KHTML
- KHTML is the HTML rendering engine for the KDE Plasma desktop, as used by the Konqueror browser. It also provides a KPart that enables all KDE applications to display web content. A new introduction, Qt WebKit is also for Plasma and other application development.
Kicker
- In KDE 3, the relocatable bar, usually at the bottom of the screen (sometimes called the Panel), on which application launchers, the Pager, and buttons for running applications reside. See Panel
Kickoff
- In KDE SC 4 (and some late versions of KDE 3), a launch menu in which apps are sorted by functional group. "Favorites" replaces the "Most used applications" in Classic Menu, and applications can be added to it. Right-click also offers the possibility of adding applications to the desktop or panel. Rapid access to a less-used application is made possible with the search box. Other menus are being worked on, since KDE SC 4 can be used with more than one launcher, should that be required.
- More info:
KJS
- KDE platform's JavaScript engine.
KInfoCenter
- Kinfocenter originated as part of KControl standing alone from KDE 3.1. In KDE SC 4 up until 4.4 it is replaced by modules configured in System Settings, notably Solid, and is being reintroduced as an application in KDE SC 4.5.
- More Info:
KIO
- KDE Input/Output framework provides a single API for operating on files, whether local or on a remote server. Additionally, KIO Slaves provide support for individual protocols. Some particularly useful ones are http, ftp, sftp, smb, nfs, ssh (fish), man, tar and zip.
Kiosk
- Kiosk is a framework for restricting user capabilities on a KDE platform system, ideal for use in locked-down environments such as Internet cafés. It is present in KDE 3 and KDE 4, but the administration tool, Kiosktool is KDE 3 only. It can be used to configure KDE 4 apps, or kiosk configurations can be maintained by editing config files manually.
KPart
- A KPart is an individual component of the KDE Plasma desktop and allows applications to share their services with other applications. KParts allow KMail and KOrganizer to integrate (as plugins) into the Kontact suite, or KHTML to display sites in Akregator.
Kross
- Kross is a scripting framework, enabling support for multiple scripting languages. A plugin system allows for the support of further languages in the future.
KRunner
- The mini-command-line that is accessed from the Classic menu, the keyboard shortcut Alt+F2, or a right-click on the desktop. In KDE SC 4 a partial name will display all possible matches
- More info:
KSVG
- KSVG enables support for scalable vector graphics in a KHTML browser. KSVG2 extends this for KDE SC 4.
KWin
- KWin is the window manager. This is where window decorations can be changed and themes applied. KDE SC 4 extends KWin to provide support for 3D Compositing effects on the desktop.
- More info:
Mini-CLI
- See KRunner
Nepomuk
- "Networked Environment for Personalized, Ontology-based Management of Unified Knowledge", Nepomuk aims to remove artificial barriers between information to allow dynamic classification, organisation and presentation of data to the user. Whether downloaded from the internet, received in an email or scribbled in a note, information is globally searchable and tagged with intelligent data. See The Semantic Desktop for further discussion of this concept.
- More info:
Oxygen
- Oxygen is the default theme of KDE SC 4. Designed to bring "a breath of fresh air" to the desktop by removing the simplistic, cartoonish icons, and replacing them with a clean theme and photo-realistic icons. Oxygen uses a desaturated palette to avoid the icons becoming a distraction and uses detailed scalable graphics (SVG).
- More info:
Pager
- A pager is a small program or panel applet which shows the position of windows on your desktop and usually, if you have several Virtual Desktops, gives an overview over all.
Panel
- See Kicker. In KDE SC 4 the name "kicker" is dropped, and the name "panel" is the norm. "Applets"; are largely replaced by Widgets
Phonon
- A cross-platform multimedia API, interfacing with existing frameworks, such as gstreamer and xine engines. KDE 2 and 3 depended on aRts for sound. Phonon replaces it.
- More info:
Plasma
- In KDE SC 4 the Plasma Desktop replaces KDesktop, kicker and the superkaramba widget engine. The applets are called Plasmoids, and range from informational widgets to mini-apps such as a calculator or dictionary. Widgets from other sources, such as SuperKaramba widgets or Google Gadgets are also supported.
- More info:
Qt
- (Pronounced "cute") A framework/toolkit for writing cross-platform applications. It is used by many cross-platform applications such as Opera browser, GoogleEarth and Skype. Qt is developed by Trolltech, who are now part of the Nokia company. Qt forms the underlying library KDE software is built on.
- More info:
Solid
- Solid provides a single API for hardware management. Hardware is grouped into "domains". The initial domains relate to HAL, NetworkManager and the Bluetooth stack. Since the backends for Solid are pluggable, Solid helps application developers write less code, and have it platform independent.
Soprano
- Soprano is a sub-project of Nepomuk, providing a repository for gathered information such as tags, ratings, etc.. This makes the information available to Strigi
Strigi
- A deep-indexed search daemon, Strigi aims to be fast and light-weight. It also uses SHA-1 hash which will help in the identification of duplicate files.
System Settings
- KDE SC 4 replacement for KControl (Control Center) providing modular control over the KDE platform.
- More info:
Threadweaver
- This thread programming library spreads work among multiple-core processors where available, prioritising them before queueing them for execution. ThreadWeaver provides a high-level job interface for multithreaded programming.
- More info:
Virtual Desktops
- A popular concept of Unix based window managers is the one of virtual desktops. This means you have not only one screen where you can place your windows on but several. When you switch to a different desktop (usually with a pager) you will only see the windows which you started on your new desktop or moved to it. A window can also be made "sticky" which means it appears on all virtual desktops.
WebKit
- HTML rendering engine, originating from a fork of KHTML. Adopted by Apple and developed for Safari. Webkit brings the whole functionality back to KDE SC 4, where it is available through Qt.
- More info:
Widget
- Collins English Dictionary: "Any small mechanism or device the name of which is unknown or temporarily forgotten." In KDE software terms, a widget is a single component on the canvas. Other common names that are analogous are "applet" or "gadget". Superkaramba Themes, Apple's Dashboard, Google Gadgets, Yahoo Widgets, Vista Sidebar Widgets, Opera Widgets are all examples of other widget systems (some of which are supported by Plasma as well).
X-Server
- The X-Server represents a basic layer upon which the various GUIs like the KDE Plasma desktop are built. It manages the basic mouse and keyboard input (from the local host as well as from remote hosts) and provides elementary graphic routines to draw rectangles and other primitives.
XMLGUI
- A programmers' framework for designing the user interface. It is extensively used by KParts
- More info:
ZUI
- The "Zooming User Interface". "By zooming out, users can get an overview of all the object groupings that they have made. These groupings may reflect the projects they are working on, be ways to keep different sets of files organized, etc. By hovering or clicking on one of these groups when zoomed out, users can either get a preview/snapshot of what is in the grouping, or zoom in on that grouping so that it is displayed full size on the physical screen." aseigo.
