system tray : Java Glossary

system tray

The bar at the bottom of the screen with tiny icons representing the programs currently running. The system tray is shared by all applications running on the desktop.

JDK (Java Development Kit)

In Java version 1.6 or later, java.awt. SystemTray lets you manage the tray if your OS (Operating System) supports it. In previous versions you will need some sort of JNI (Java Native Interface) code. There are a number of third party tools.

Linux

In Gnome it is referred to as the Notification Area, on KDE (K Desktop Environment) it is referred to as the System Tray. In Gnome, the default GUI (Graphic User Interface) for Ubuntu Linux, there is the panel. A strip across the top contains the menus. A strip across the bottom has a buttons such as ones to navigate between desktops. Part of it is the system notification area e.g. a message that updates are available.

Windows

In Windows, the sytem tray takes the form of a strip strip, usually at the bottom of the screen, called the task bar. The far left section of it is called the quicklaunch bar, and is for the icons of frequently launched programs. In the middle are icons for running programs. This region is sometime called the slit. On the far right are small icons for background tasks, e.g. for controlling devices such as the display, mouse, volume, keyboard layout…. Thee icons on the middle and right are sometimes called the system tray. Some people reserve the term system tray only for the icons on the right. Right clicking them lets you interact with the running program, usually exit and restore.

Vista

In Windows Vista, you have the following areas:
