Deskbar（桌面栏）

桌面栏是默认放置在屏幕右上角的小面板。它类似于windows的带着开始菜单的任务栏。它包含了桌面栏菜单，而通过它您可以启动应用程序和设置程序，时钟托盘和其他托盘程序程序，以及当前正在运行程序得列表。

你通过把鼠标点击在系统托盘有纹饰的一侧，然后进行拖拽，把桌面栏移动到屏幕的任意角落或者展开放置在屏幕的顶部和底部边界；你也自己设计一个更紧凑的菜单布局，然后把它拖拽至桌面栏菜单。

桌面栏菜单

点击桌面栏顶部会打开一个菜单：

• About This System... - 展示了有关Haiku操作系统，Haiku项目的许可证和致谢名单等的基本信息。

• Find... - 打开 查询 会话框。

• Show Replicants - 显示或者隐藏 Replicant 微控件，您可以对它进行随意的拖动，删除或者访问它的快捷菜单。

• Mount - 提供了和右键点击桌面时相同的选项。（详细介绍请查阅 挂载磁卷）。

桌面栏首选项

• 菜单
  Here you can set the number of recent documents, folders and applications that are shown in their menu in the Deskbar, or if you want to see them at all.
  The button Edit Menu... opens the folder /boot/home/config/be/. In it you'll find the files and folders that appear in the Deskbar, by default these are Applications, Demos, Deskbar Applets, and Preferences.
  You can delete or add entries like links to applications, documents or even queries by simply copying/deleting them to/from this folder.

  It's even easier to simply drag a file, folder or saved query and drop it where you want it into the Deskbar.

系统托盘

Among other things, the tray is housing the clock. Left-click it to toggle between date and time. Right-click it to hide/show it or launch the Time preferences to set it.
Here you can also launch a calendar that also appears, when you hold down the left mouse button on the clock for a little time.

Any program can install an icon in the tray to provide an interface to the user. The email system, for instance, shows a different symbol when there's unread mail and offers a context menu to e.g. create or check for new mail. ProcessController is another example that uses its icon in the tray to provide information (CPU/memory usage) and to offer a context menu.

运行程序

You can change to a specific running application by clicking on its entry in the Deskbar and choosing (one of) its windows, from the submenu. By right-clicking you can minimize or close a window or the entire application.

If you activated Expanders in the Deskbar settings, you can expand/collapse the list of windows directly under an application's entry.

In front of every application's windows is a symbol providing info on its state. A bright symbol means a window is visible, a dark one that it's minimized. Three lines in front of a symbol shows that it's not on the current workspace.
