Aktivity (Activities)

Aktivity jsou sady Plasma widgetů, které mají vlastní tapetu. Trochu jako Virtuální pracovní plochy, ale né tak zcela.

Máte například "pracovní aktivitu" se zobrazenou čtečkou RSS, poznámky napsané v TODO widgetu, Pohled na složku s vašimi pracovními soubory a odpovídající tapetou

Vedle toho máte vaší "volnočasovou aktivitu", s náhledem na rodinné fotky, čtečku RSS se zprávami vašeho oblíbeného blogu, Pohled na složku s vaší video knihovnou, twitter applet a samozřejmě tapetu s Iron Maiden, které milujete už od osmdesátek.

Přesně v 17:00 přepnete svoji "pracovní aktivitu" na vaši "volnočasovou aktivitu".

Akonadi

Mechanika přístupu k datům všech "PIM" (správců osobních údajů - Personal Information Manager) v KDE. To umožňuje různým aplikacím přistupovat k požadovaným informacím na jednom místě. Neznamená to ovšem, že používání Akonadi mění formát ukládaných dat (vcard, iCalendar, mbox, maildir atp.) - poskytuje pouze nový způsob přístupu a použití osobních údajů.

Hlavní důvod pro vývoj Akonadi je technická povaha, tzn. mít unikátní způsob přístup k datům PIM (kontakty, kalendáře, e-maily...) z různých aplikací (např. KMail a Calligra) a tím eliminovat potřebu opakovaně psát podobný kód.

Dalším důvodem je oddělení aplikací s GUI jako KMail od přímého přístupu k externím zdrojům, jako jsou mail servery -- to byl v minulosti hlavní požadavek v záznamu bugů a přání vzhledem k výkonu resp. odezvě.

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. D-Bus allows multiple programs to interact. Developed by Red Hat^®, it was heavily influenced by KDE3's DCOP, which it supersedes.

Dolphin

The default file manager in KDE Plasma. It has a side panel (Places), but navigation is mainly by the breadcrumb trail above the main window. It has various advanced features such as split windows and individual views in different 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.

Flake

Flake is a programming library to be used in Krita and Calligra. 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 Information:

• KDE Community Wiki - Flake

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.

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 Information:

• Wikipedia - Home directory

KHTML

KHTML is a HTML rendering engine that was the base of WebKit, the engine that powers many browsers still in use today (e.g. Safari).

Kirigami

Kirigami is a set of components allowing developers to create applications that looks good and works well on mobile platforms as well as on the desktop.

More Information:

• Kirigami on kde.org

Kickoff

Kickoff is a launch menu in KDE Plasma in which apps are sorted by functional groups. 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. There are also alternatives, such as the fullscreen app dashboard.

• Design documentation

KJS

KDE platform's JavaScript engine.

KInfoCenter

KInfoCenter originated as part of KControl standing alone from KDE 3.1. It can display data about your system such as energy usage, hardware info and many more.

More Information:

• KInfoCenter
• Wikipedia - KInfoCenter

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, google drive, 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 has been unmaintained for quite some time now.

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.

More Information:

• KRunner wiki

KWin

KWin is the window manager of KDE. This is where window decorations can be changed and themes applied.

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 Plasma the name "kicker" is dropped, and the name "panel" is the norm. "Applets"; are largely replaced by Widgets

More Information:

• Panels

Phonon

A cross-platform multimedia API, interfacing with existing frameworks, such as gstreamer and xine engines.

Qt

(Pronounced "cute") A framework/toolkit for writing cross-platform applications. It is used by many cross-platform applications such as Krita, GoogleEarth and many others. Qt forms the underlying library KDE software is built on.

More Information:

• The Qt Toolkit

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.

More Information:

• Discover Solid

System Settings

The system settings are the unified place where you can change and customize many aspects of the Plasma desktop and KWin such as icon themes, desktop effects and shortcuts.

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 Information:

• 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 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.

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
