教學/KDE3 to KDE SC 4
Note
SC 4？那是什麽？ KDE打包了很多程式進核心軟體包（core packages）。它們被稱為軟體彙集（Software Compilation）。為方便起見，我們縮寫它為SC 4。
乍看之下，KDE SC 4 缺少一些在 KDE 3 中有價值的功能。事實上，大多數的功能都可用，但很可能是用不同的方式操作。想像一下，一個'道路封閉'標誌-您只需選擇替代路線。
一個特別的'缺少功能'案例是從 kcontrol 到系統設定。有些 kcontrol 設定與具體應用程式有關。因此，這些設定已轉移到該應用程式，而不是在一般的控制面板。
替換的新方法
kcontrol已經沒了
KControl不再存在。有着交叉工具圖示的系統設定（Systemsettings）取代了 kcontrol。預設情況下，使用圖示檢視，以組的形式排序。你可能喜歡用切換到。
建立桌面上的圖示
使用傳統桌面
KDE SC 4 下有兩種類型的桌面，兩者兼有可能是你發行版本的預設值。右擊桌面，選擇桌面設定（有些發行版本又叫外觀設定），選擇你要的類型：桌面（適合喜歡乾淨和清爽桌面的人）或資料夾檢視（這種桌面的操作習慣類似 KDE 3 桌面）。
不同的方法
要是需要實用的更簡潔的桌面的話，試著用「桌面」類型，擺放一個小的指向你的數據目錄的「資料夾檢視」到螢幕的角落（他可以滾動），一個很不錯的細節是如果你懸停鼠標指針到一個文件夾上，他會顯示下一層的目錄樹，因此你可以不用再開檔案管理器便可直接打開某個檔案。
附注
也試下在krunner（可以用alt+F2或桌面的右鍵關聯選單裡打開）裡輸入名稱（或部分名稱或功能）。Krunner 用的是模糊搜索，所以如果你輸入'write'他會提供的已安裝程式，可能是kwrite，openoffice-writer，kword或googledocs以及所有有關的書籤，你不需要記住太準確。
Or Drag'n'Drop?
You can drag an icon onto the desktop in Desktop type, as well as in Folderview type. You will be presented with options suited to the type of file. For instance, if you drop an image onto the desktop you are offered Previewer (which opens the file, giving you icons for the options to open it in a relevant application, or delete the file - move to trash), open in a PhotoFrame, or place an icon for it on the desktop. If you don't see the Previewer option you may need to install kdeplasma-addons.
Another function of drag-n-drop from Dolphin is to drag a folder to create a folderview. Remember that you can scale it to suit yourself, as you will have a scroll-bar. You can even descend through the tree of a folder just by hovering, so opening a single file is much quicker than opening a file manager to find it.
Automounting of USB devices
In KDE 3 you could choose to have usb devices mounted automatically upon plugin. In KDE SC 4 this is not the norm. You mount manually, either from the device notifier, by choosing an action, or by clicking on the device icon in Dolphin. From KDE SC 4.2 it has been possible to use an alternative device notifier plasmoid that does support automount functionality. You can read about it here
Alternative approach:
Advanced users may prefer to study the creation of usb device rules. Documentation can be found in the writing udev rules guide.
Note
Auto-hide Panels
To achieve this click on the plasma configurations icon (yellow curvy thing at the right hand side of the panel) and select . Then under enable "autohide". Manual hiding, as in KDE3, is currently not possible.
Move applets on the panel
In KDE SC 4 you have to bring up panel control (use the plasma toolbox icon, the yellow curvy thing at the right hand end of the panel). If you lock your widgets (or your distro does by default) you will first need to unlock widgets. This can be done from the right-click menu on the desktop. When your cursor moves over a widget (or plasmoid) it changes to a diamond shape. Use that cursor to drag each widget to its new place.
Finish by clicking on the X in a red circle on the configuration panel, and lock your widgets again if you wish, (right click menu, as before).
KDE3 used to let you configure whether you wanted to see the application name (e.g. amarok) or the description (e.g. media player). KDE SC 4 always shows only the description and this makes it very hard to find applications.
If you use 'Kickoff Menu Style', you can easily find an application by typing the first few letters of its name in the "Search" line of the Application Launcher. Once you have found it you can choose to add it to Favorites or to add a launcher icon into the panel or on the desktop.
If you dislike the 'click on everything' style of Kickoff you may like to try Lancelot which has most of the advantages of Kickoff and some nice tricks of its own.
If you prefer the old K menu, then right click the K menu icon and choose . Now you can configure how to show applications in the menu: Right click on the . Check the option, click . Done.
