Plasma 4.4 常见问题
Template:I18n/Language Navigation Bar
Plasma工作空间（The Plasma Workspace）是 KDE SC 4 中一个关键技术 (被誉为 “KDE 的支柱”)，是用户最直观的东西。由于 Plasma 不同于传统桌面的方式对待用户界面，可能会有关于 Plasma 是什么、它做些什么、以及如何进行常规任务的疑惑。
本文档将通过一些最常见问题的解答来试图理清这些问题。
常规问题
Plasma 是用来干什么的？
Plasma 是 KDE 的默认工作空间（workspace）（桌面界面）。它包括一个程序启动器（开始菜单），桌面和桌面面板（经常特指任务栏面板)。然而Plasma不仅仅是工具的类似收集而已, 她是一个通用的创建整合界面的框架。 她足够灵活到为移动设备（手机和上网本），多媒体中心和桌面电脑提供操作界面；让传统的桌面比拟（the traditional desktop metaphor）支持那样设计的那样是无法想像的。
Plasma 是如何工作的？
Plasma 的主要组件是部件。部件具有各式各样的功能，从展现你的桌面和指定的墙纸、显示你的笔记本电池电量、显示你插入的设备到绘制任务栏：基本上，它们是生活在桌面上的小程序。此外，部件可以按组聚合在“容器”中，像是面板，甚至是桌面本身。
What is the Folder View applet?
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.
