Editing Taskbar (section)

== Antecedents ==

=== Windows 1.0 ===
[[Windows 1.0]], released in 1985, features a horizontal bar located at the bottom of the screen where running programs reside when minimized (referred to as "iconization" at the time), represented by icons. A [[Window (computing)|window]] can be minimized by double-clicking its [[title bar]], dragging it onto an empty spot on the bar, or by issuing a command from one of its [[Menu (computing)|menu]]s. A minimized window is restored by double-clicking its icon or dragging the icon out of the bar.

The bar features multiple slots for icons and expands vertically to provide the user with more rows as more slots are needed. Its color is the same as that of the screen background, which can be customized. Minimized windows can be freely placed in any of the empty slots. Program windows cannot overlap the bar unless maximized.

The [[Start button]] did not make an appearance in these early implementations of the taskbar, and would be introduced at a much later date with the release of [[Windows 95]].

=== Arthur ===
Another early implementation can be seen in the [[RISC OS|Arthur]] operating system from [[Acorn Computers]]. It is called the ''[[icon bar]]''<ref name="Ryan2011">{{cite book|author=Dan Ryan|title=History of Computer Graphics: DLR Associates Series|url=https://books.google.com/books?id=136myWlKpwEC&pg=PA358|access-date=13 June 2013|date=13 April 2011|publisher=AuthorHouse|isbn=978-1-4567-5115-9|page=358}}</ref> and remains an essential part of Arthur's succeeding [[RISC OS]] operating system. The icon bar holds icons which represent mounted disc drives and RAM discs, running applications and system utilities. These icons have their own context-sensitive menus and support drag and drop behaviour.

=== Amiga ===
[[AmigaOS]] featured various third party implementations of the taskbar concept, and this inheritance is present also in its successors. For example, [[AmiDock]], born as third-party utility, has then been integrated into AmigaOS 3.9 and AmigaOS 4.0.<ref>[http://www.qdev.de/?location=amiga/amidock Amiga Amidock Homepage]</ref> The [[AROS]] operating system has its version of [[Amistart]] that is provided with the OS and free to be installed by users, while [[MorphOS]] has been equipped with a dock utility just like in AmigaOS or [[Mac OS X]].
