Paned window (computing)

A paned window is a windows (or build-ups) in a graphical user interface that has multiple parts, layers, or sections. Examples of this include a code browser in a typical integrated development environment; a file browser with multiple panels; or a web page that contains multiple frames. Simple console applications use an "edit pane" for accepting input and an "output pane" for displaying output.
The term "task pane" is used by Microsoft to identify any area cordoned off from the main screen area of an application and used for a specific function, such as changing the displayed font in a word processor.
