xfce4-panel
also: xfce panel, Xfce panel
A lightweight panel application for the XFCE desktop environment that provides a taskbar, application launcher, and system tray for managing windows and accessing programs.
xfce4-panel is the main panel component of the XFCE (Xfce is an Acronym Free Classical Environment) desktop, typically displayed at the top or bottom of the screen. It serves as a hub for launching applications, switching between open windows, and accessing system utilities.
The panel is highly customizable—users can add or remove plugins, change the panel size, position it on any screen edge, and adjust transparency and appearance settings. Common plugins include application menus, a clock, system monitor, network manager, and volume control.
Example: Running xfce4-panel & in a terminal starts the panel process. Users can right-click the panel to access its preferences menu and add widgets like a calendar or search launcher.
