Γλωσσάρι
Σκοπός της συγκεκριμένης σελίδας είναι να παρέχει μη-τεχνικές αναφορές, όπως επίσης και υπερσυνδέσμους για περαιτέρω πληροφορίες ή παρουσιάσεις.
Γενική Επισκόπηση
Το KDE 4.0 Visual Guide: και το 4.1 screencast παρέχουν μια εξαιρετική επισκόπηση του KDE Software Compilation 4 τις πρώτες του ημέρες (στα αγγλικά).
Το γλωσσάρι που ακολουθεί έχει ως στόχο να σε βοηθήσει να βρεις το δρόμο μέσα στο θολό τοπίο των νέων ονομάτων και εννοιών. Σε ορισμένες περιπτώσεις μπορεί να συναντήσεις έναν υπερσύνδεσμο από ένα συστατικό του KDE 3 προς το αντίστοιχο του στο περικείμενο του KDE SC 4 λογισμικού.
Δραστηριότητες
- Οι Δραστηριότητες είναι σύνολα από συστατικά (widgets) Plasma που έχουν τη δική τους επιφάνεια εργασίας. Κάτι σαν τις Εικονικές Επιφάνειες Εργασίας, αλλά όχι ακριβώς.
- Για παράδειγμα έχεις μια δραστηριότητα εργασίας με τροφοδοσίες rss, μια σημείωση με τα TODO σου και μια Προβολή Φακέλου με τα σχετικά με την εργασία σου αρχεία και ένα διακριτικό φόντο.
- Λίγο πιο δίπλα, έχεις τη δραστηριότητα ελεύθερου χρόνου, με προεπισκόπηση των οικογενειακών σου φωτογραφιών και των σκυλιών σου, τροφοδοσίες rss, από τα αγαπημένα σου blogs, μια Προβολή Φακέλου που δείχνει τη συλλογή με τις ταινίες σου, μια μικροεφαρμογή twitter και φυσικά ένα φόντο με τους Iron Maiden που λατρεύεις από τις αρχές του 80.
- Στις 17.00 ακριβώς αλλάζεις από τη δραστηριότητα εργασίας στη δραστηριότητα ελεύθερου χρόνου.

Akonadi
- Μηχανισμός προσπέλασης αποθηκευμένων δεδομένων για όλα τα δεδομένα PIM (Διαχειριστής Προσωπικών Πληροφοριών) στο KDE SC 4. Ένα μοναδικό σύστημα αποθήκευσης και ανάκτησης επιτρέπει αποτελεσματικότητα και επεκτασιμότητα, κάτι που δεν ήταν δυνατό στο KDE 3, όπου κάθε PIM συατατικό είχε το δικό του σύστημα. Σημειώστε πως η χρήση του Akonadi δεν αλλάζει τη μορφή αποθήκευσης των δεδομένων (vcard, iCalendar, mbox, maildir κλπ.) - απλά παρέχει ένα νέο τρόπο πρόσσπέλασης και επεξεργασίας των δεδομένων.
- Οι βασικοί λόγοι σχεδιασμού και ανάπτυξης του Akonadi είναι τεχνικής φύσης, π.χ. το να έχεις ένα μοναδικό τρόπο πρόσβασης στα δεδομένα PIM(επαφές, ημερολόγια, μηνύματα ηλεκτρονικού ταχυδρομείου...) από διαφορετικές εφαρμογές (π.χ. kmail, kword...), ελαχιστοποιώντας την ανάγκη να γράφεις παρόμοιους κώδικες από δω κι από εκεί.
- Ένας άλλος στόχος είναι να αποσυνδέσει τις εφαρμογές διεπαφής χρήστη (GUI) όπως το kmail από το να έχουν απ' ευθείας πρόσβαση σε εξωτερικούς πόρους όπως οι διακομιστές αλληλογραφίας - κάτι που ήταν ο κύριος λόγος αναφοράς σφαλμάτων/επιθυμιών ως προς την απόδοση/αποκριτικότητα στο παρλεθόν.

aRts
- Το πλαίσιο ανάπτυξης (framework) στα KDE 2 και 3. Η μονο-επεξεργαστική του φύση προκαλούσε προβλήματα όταν υπήρχαν δυο πηγές ήχου. Στο χώρο εργασίας Plasma αντικαταστάθηκε από το Phonon.

Υποδοχέας
- Ένας Υποδοχέας είναι μια ομαδοποίηση συστατικών σε ένα παραπάνω επίπεδο. Κάθε Υποδοχέας διαχειρίζεται τη διάταξη και τα δεδομένα παραμετροποίησης του συνόλου των συστατικών του ξεχωριστά, ανεξάρτητα από τους άλλους Υποδοχείς.
- Το τελικό αποτέλεσμα είναι ότι μπορείς να ομαδοποιήσεις συστατικά μέσα σε έναν Υποδοχέα σύμφωνα με τη σημασία τους στο δικό σου μοντέλο εργασίας και όχι με ομαδοποίηση καταλόγου.
D-Bus
- Ένα σύστημα επικοινωνίας μέσω μηνυμάτων μεταξύ των υπηρεσιών. Αναπτύχθηκε από τη Red Hat®, επηρεασμένο σε μεγάλο βαθμό από το DCOP του KDE3 το οποίο και διαδέχεται.

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.

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.

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.
More info:
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.

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.

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
More info:
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.

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.
More Info:
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
More info:
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.
More info:
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.
