A panel is "a particular arrangement of information grouped together for presentation to users in a window or pop-up".1 In ISPF, a panel is "a predefined display image that you see on a display screen".2: p.16 In modern multiple-document interface software a panel refers to a particular arrangement of information grouped together and presented to users docked (by default) in the user interface rather than floating in a window, pop-up or dialog box.
A panel graphical control element is commonly packaged as part of a widget toolkit (libraries that contain a collection of graphical control elements) for a graphical user interface. See toolbar and dialog box.
