Kicker (also referred to as KDE Panel) is the main panel used in KDE 3 and earlier, and also in the TDE desktop. Together with KDesktop, it forms the graphical shell. It can be customized by the user. By default, it has the K Menu, a Desktop Access button, a Home button, a Konqueror button, a Kontact button, and a Help button. It also has the Desktop Preview & Pager, the Taskbar, the System Tray, and the Clock.
It was a core part of the KDE desktop, and as such, packaged as part of the kdebase module. Kicker was also ported from Qt3 to Qt4.
Kicker can be launched separately in other windowing environments that lack a panel of their own, such as twm, and in case the twm menu lacks some of the commands that Kicker may have. This can be done by editing a .twmrc file, or from a terminal emulator:
$ kicker &
