SC 4？那是什么？ KDE打包了很多程序进核心软件包（core packages）。它们被称为软件汇集（Software Compilation）。为方便起见，我们缩写它为SC 4。

乍看之下，KDE SC 4 缺少一些在 KDE 3 中价值的功能。事实上，大多数的功能都可用，但很可能是用不同的方式操作。想象一下，一个'道路封闭'标志-您只需选择替代路线。

一个特别的'缺少功能'案件是从 kcontrol 到系统设定。有些 kcontrol 设定与具体应用程序有关。因此，这些设定已转移到该应用程序，而不是在一般的控制面板。

替换的新方法

kcontrol已经没了

kcontrol已经没了。有着交叉十字工具图标的 系统设置（Systemsettings）取代了他。默认情况下，他用的是图标视图，以组的形式排序。你可能喜欢用 配置 选项（扳手图标）切换到 经典树形视图 。

在桌面上创建图标

使用经典桌面类型

KDE SC 4下有两个类型的桌面，两者兼有可能是你发行版的默认值。右击桌面，选择桌面设置（有些发行版又叫外观设置），选择你要的类型：桌面（适合喜欢干净和separse桌面的人）或文件夹视图（这种桌面的操作习惯类似KDE3桌面）。

一种不同的方法

要是需要实用的更简洁的桌面的话，试着用「桌面」类型，摆放一个小的指向你的数据目录的「文件夹视图」到屏幕的角落（他可以滚动），一个很不错的细节是如果你悬停鼠标指针到一个文件夹上，他会显示下一层的目录树，因此你可以不用再开文件管理器便可直接打开某个文件。

Note

In 4.4 you have to click the up-arrow to descend the tree.

也试下在krunner（可以用alt+F2或桌面的右击关联菜单里打开）里输入名称（或部分名称或功能）。Krunner用的是模糊搜索，所以如果你输入'write'他会提供的已安装程序，可能是kwrite，openoffice-writer，kword或googledocs以及所有有关的书签，你不需要记住太准确。

或 拖放？

你能在「桌面类型」以及「文件夹视图类型」里拖动一个图标到桌面上。系统会提供给你适合这个文件类型的选项。例如，如果你拖动一幅图片到桌面上，会提供给你在「桌面相框」里打开，或放置一个链接到该文件的图标在桌面，或设置成桌面「壁纸」。

另一个从Dolphin里拖放的功能是拖动文件夹创建文件夹视图。记住你能缩放他直到满意为止，里面会有滚动条。你甚至能悬停鼠标浏览一个文件夹里面的内容，所以打开一个单独的文件要比特地打开文件管理器找到他快很多。

自动挂载USB设备

在KDE3里你能选择用插件自动挂载usb设备。KDE SC 4中不一样。你要手动挂载，或是从设备通知器部件，选择一个操作，或是点击Dolphin里的设备图标。KDE SC 4.2之后，有个可选的设备通知器plasmoid支持自动挂载功能。点击这里查看。

备选方法：

Advanced users may prefer to study the creation of usb device rules. Documentation can be found in the writing udev rules guide.

Note

Both these are temporary measures. Automounting may be restored in a later release.

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 configure panel. Then under more options 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).

Show the application name instead of the description in the K - menu

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 Switch to Classic Menu Style. Now you can configure how to show applications in the menu: Right click on the K icon -> Application Launcher settings. Check the Show applications by name option, click OK. Done.
