A panel can hold several types of objects. The panel in Figure 2–2 contains each type of panel object.
You can add any of the following objects to all types of panels:
Applets
Applets are small, interactive applications that
reside within a panel, for example CD Player
in Figure 2–2. Each applet has a simple user interface that
you can operate with the mouse or keyboard. The following applets appear in
your panels by default:
Window List
: Displays a button
for each window that is open. You can click on a window list button to minimize
and restore windows. By default, Window List
appears
in the edge panel at the bottom of the screen.
Workspace Switcher
: Displays a
visual representation of your workspaces. You can use Workspace
Switcher
to switch between workspaces. By default, Workspace Switcher
appears in the edge panel at the bottom of
the screen.
To add an applet to a panel, right-click on a vacant space on the panel, then choose Add to Panel. Choose the applet that you require from one of the following submenus:
Accessories
Amusements
Internet
Multimedia
Utility
Launchers
A launcher starts a particular application, executes
a command, or opens a file. The calculator icon in Figure 2–2
is a launcher for the Calculator
application. A
launcher can reside in a panel or in a menu. Click on the launcher to perform
the action that is associated with the launcher.
You can create your own launchers for applications. For example, you can create a launcher for a word processor application that you use frequently, and place the launcher in a panel for convenient access. To add a new launcher to a panel, right-click on a vacant space on the panel, then choose Add to Panel -> Launcher.
Alternatively, to add a launcher from a menu, right-click on a vacant space on the panel, then choose Add to Panel -> Launcher from menu. Choose the launcher to add from the submenus.
Menus
You can access all desktop environment functions through menus. The default panels contain menus, so you can use a combination of menus and panels to perform your tasks. To open a menu from a panel, click on the icon that represents the menu. To open a menu from the Menu Panel, click on the text that represents the menu.
Menus that you add to your panels are represented by an icon with an arrow. The arrow indicates that the icon represents a menu. The icon in Figure 2–2 is the icon that is displayed when you add the Desktop Preferences menu to a panel.
You can also add the GNOME Menu to any of your panels. To add the GNOME Menu to a panel, right-click on a vacant space on the panel, then choose Add to Panel -> GNOME Menu.
Drawers
Drawers are sliding extensions to a panel that you can open or close from a drawer icon, as shown in Figure 2–2. Drawers can help you to organize your work when you run a lot of applications simultaneously. You can place all the same functional elements in a drawer that you can put in any other type of panel.
To add a drawer to a panel, right-click on a vacant space on the panel, then choose Add to Panel -> Drawer.
To open a drawer click on the drawer. To close a drawer click on the drawer again.
Lock button and Log Out button
The Lock button enables you to lock your screen. The lock icon in Figure 2–2 is the Lock button. The Log Out button enables you to end your session.
To add the buttons to a panel, right-click on a vacant space on the panel, then choose Add to Panel. You can then choose the button you require.
