Plasma/FAQ/4.4
Template:I18n/Language Navigation Bar
Plasma工作空間（The Plasma Workspace） 是 KDE SC 4 中一個關鍵技術(被譽為「KDE 的支柱」)，是使用者最直觀的東西。 由於 Plasma 使用者介面操作不同於傳統桌面的方式，可能會有關於 Plasma 是什麼、它做些什麼、以及如何進行一般任務的疑惑。
本檔案將透過解答一些最常見問題試圖來理清這些問題。
Information
一般問題
Plasma 是作什麼的？
Plasma 是KDE 的默認工作空間（workspace）（桌面界面）。它包括一個程式啟動器（開始選單）、桌面和桌面面板（經常特指工作列)。 然而 Plasma 不僅僅是類似工具的集合而已，她是一個創建整合介面的通用框架。她足夠靈活到為移動設備（手機和小筆電）、多媒體中心和桌面電腦提供操作介面；想讓傳統的桌面比擬（the traditional desktop metaphor）支持那樣設計的那樣是無法想像的。
Plasma 是如何運作的？
Plasma 的主要組件是元件。元件具有各式各樣的功能，從展現你的桌面和指定的牆紙、顯示你的筆記本電池電量、顯示你插入的設備到繪製任務欄：基本上，它們是生活在桌面上的小程式。 Plasmoids 可以按組聚合在叫「容器」中，像是面板，甚至是桌面本身。
「資料夾檢視元件」是什麼？
The Folder View applet, like its name says, is used to display items (folders, files) from a directory. Such a directory can be either a local one residing on your computer, but also a remote FTP, SSH, or SMB share. In the future, it will even contain results from Nepomuk searches and tagging.
You can choose to view either all files, or filter either by specific regular expressions (e.g., all files with a certain extension) or by file type (for example, just images).
This applet also supports basic file management properties (moving, copying, cutting and pasting for example), and you can have as many as you want on your desktop.
Lastly, you can use one Folder View as the whole desktop, effectively replicating the "old style" desktop paradigm.
What is KRunner?
KRunner is the versatile mini-command line you can activate by pushing "Alt-F2" or by selecting "Run Command" from the desktop contextual menu. It can search for applications, bookmarks, even sessions basing on your input, show system activity and even do simple arithmetic calculations.
KRunner's functionality can be extended through the use of plugins ("runners").
What are the "cashews"?
What is commonly referred as "cashew" is the Plasma toolbox, the logo you can find on the default desktop, on the upper right corner, and on the panel, on the right hand side (left hand side if you use a Right-To-Left language). By clicking on them, you can access other configuration options. Some of these only appear if the widgets aren't locked (see below).
Please provide an option to disable the upper right cashew.
Although putting an option to disable the cashew for desktops sounds reasonable, from a coding point of view it would introduce unnecessary complexity and would break the design. What has been suggested is, since the destkop itself (a containment) is handled by plugins, to write a plugin that would draw the desktop without the cashew itself. As a matter of fact, some distributions ship already a "Desktop without cashew" plugin.
What is the Zooming User Interface (ZUI)?
The Zooming User Interface, or ZUI, is another component of Plasma. It enables the user to group different groups of plasmoids together, and to quickly switch between one and another using a zoom-and-pan approach. Notice that the Zooming User Interface is going to be radically changed for the 4.5 release of the KDE SC.
How does the ZUI work?
Suppose you have three groups of plasmoids (such as widgets, application launchers, etc.) which you want arranged in specific combinations depending on what you want to do. You first group them according to your tastes, then you can switch between them by zooming out (getting a preview of all the groups) and then back in on the specific group you want to use. Notice that it is different from traditional X11 virtual desktop switching, as there is a higher degree of flexibility by using this approach, as the groups can be totally different from each other.
A very good example of this behavior is shown by this image courtesy of Half-Left from #kde on freenode.
That said, you can tie virtual desktops to ZUI activities.
