Revision as of 05:41, 15 September 2008

This page sets out to provide a non-technical reference, together with links for further information or demonstration. It should be noted that not all of the KDE 4 developments are available in 4.0. Some maynot be ready for 4.1.

A General Overview

A KDE 4.0 Visual Guide: and a 4.1 screencast give an excellent overview of KDE 4.

The following table is intended to help you find your way through the mists of new names and new concepts. In some cases you can find a link from a KDE 3 component to its equivalent in KDE 4.


Activities Activities are sets of Plasma widgets that have their own wallpaper. A bit like virtualdesktops, but not quite.

For example you have a "work activity" with commit rss feeds, a note with your TODO, a folderview with your work related files, and a subtle wallpaper.

Next to it, youhave your freetime activity, with previews of family photos and dogs, rss feeds from your favourite blogs, a folderview showing your movie collection, a twitter applet and of course that Iron Maiden wallpaper you have been loving since the early 80s.

At 1700 hours sharp you switch from the work activity to your freetime activity.

More info:

Creating Activities

Akonadi The data storage backend for all PIM (Personal Information Manager) data in KDE 4. One single storage and retrieval system allows efficiency and extensibiliy not possible under KDE3, where each PIM component had its own system. More info:

Akonadi - KDE PIM

Wikipedia - Akonadi

Techbase - Akonadi

aRts The sound framework in KDE 2 and 3. Its single-tasking nature caused problems when two sources of sound were encountered. In KDE 4 it is replaced by Phonon More info:

Wikipedia - aRts

aRtsHome Page

Containment A Containment is a top level grouping of widgets. Each Containment manages the layout and configuration data of its set of widgets independently from other Containments.

The end result is that you can group widgets within a containment according to the significance to your working pattern, rather than by directory grouping.

D-Bus An inter-service messaging system. Developed by RedHat, it was heavily influenced by KDE's DCOP, which it supercedes. More info:

FreeDesktop.org: What is D-Bus?

Wikipedia: D-Bus

Decibel Using D-Bus, Decibel is the framework to manage all communication protocols including IM, email and VOIP through a unified system. Decibel is expected to be fully functional by KDE 4.2. More info:

Dolphin The default file manager in KDE4. It has a side panel, 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. More info:

Wikipedia- Dolphin_(software)

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 will enter Plasma for KDE 4.2. The Kuiserver (the interface that collects all long running jobs and puts them into one window, also planned for that release) will make use of extenders so you can detach various jobs and monitor their progress separately. More info:

The Elements of Plasma

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 towork as a single Shape, around which text flow is possible. More info:

KOffice Wiki - Flake

KControl KDE Control Center, for setting global preferences in KDE3. Replaced by KDE4's System Settings interface.
KDOM A KPart module making KHTML DOM (Document Object Model) rendering capabilities available to all applications. [[#KSVG2]|KSVG2]] is built on KDOM for KDE 4.
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 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 can be by the search box. Other menus are being worked on, since KDE 4 can be used with more than one launcher, should that be required. More info:

Kickoff Sneak Preview

KJS KDE's JavaScript engine.
KHTML KHTML is the HTML rendering engine for the KDE desktop, as used by KDE's Konqueror Browser. It also provides a KPart that enables all KDE applications to display web content. KDE4 also sees the introduction of Qt WebKit for Plasma and other applications.
KIO KDE Input/Output framework provides a single API for operating on files, whether local or on aremote 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. More info:

Breaking the Network Barrier

KInfoCenter Kinfocenter originated as part of Kcontrol standing alone from KDE 3.1. In KDE 4 it is replaced by modules configured in System Settings, notably Solid More Info:

Wikipedia - KInfoCenter

Kiosk Kiosk is a framework for restricting user capabilities on a KDE system, ideal for use in locked-down environments such as Internet cafés. Currently available in KDE 3 only.
KPart A KPart is an individual component of the KDE desktop environment 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 KDE 4 support for multiple scripting languages. Aplugin system allows for the support of further languages in the future.
KRunner the mini-command-line that is accessed from the KDE Classic menu, the keyboard shortcut Alt+F2, or a right-click on the desktop. In KDE4 a partial name will display all possible matches More info:

Youtube - KDE 4.1 KRunner

KSVG KSVG enables support for scalable vector graphics in a khtml browser. KSVG2 extends this for KDE 4.
KWin KWin is the window manager. This is where window decorations can be changed and themes applied. KDE4 extends KWin to provide support for 3D Compositing effects on the desktop. More info:

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 inan 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 KDE4. Designed to bring 'a breath of fresh air' tothe 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:

Wikipedia - Oxygen Project

Oxygen Icons

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 KDE4 the name 'kicker' is dropped, and the name 'panel' is the norm. 'Applets' are 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:

Wikipedia - Phonon (KDE)

Phonon website

Plasma In KDE 4 Plasma 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. 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:

Why Multithreading? (Technical article)

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 newdesktop 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 4, where it is available through Qt. More info:
