A '''slider''' is an object in a [[GUI]] with which a user may set a value by moving an indicator, usually in a horizontal fashion. In some cases the user may also click on a point on the slider to change the setting. It is different from a [[Scrollbar]] in that it is typically used to adjust a value without changing the format of the display or the other information on the screen.

A '''slider''' or '''track bar''' is a [[graphical control element]] with which a user may set a value by moving an indicator.<ref>{{Cite book |last=Eick |first=Stephen G. |chapter=Data visualization sliders |date=1994-11-02 |title=Proceedings of the 7th annual ACM symposium on User interface software and technology - UIST '94 |chapter-url=https://dl.acm.org/doi/abs/10.1145/192426.192472 |___location=New York, NY, USA |publisher=Association for Computing Machinery |pages=119–120 |doi=10.1145/192426.192472 |isbn=978-0-89791-657-8 |quote=Sliders are a general-purpose user input mechanism enabling users to specify a single input value from a well-defined range. They are widely used in all graphical user-interface systems.... Sliders are easy to use, intuitive, and provide a sensitive mechanism for specifying values. Sliders have a threshold bar positioned within a scale that the user manipulates with a mouse to select a value. Graphical input tools with similar function include dials, bars, pointers, gauges, and potentiometers.}}</ref> In some cases the user may also click on a point on the slider to change the setting. It is different from a [[scrollbar]] in that it is not continuous but used to adjust a value without changing the format of the display or the other information on the screen.

Its most popular use is for viewing and jumping to a playback position in [[media player software]].{{citation needed|date=May 2025}}

== Usage with progress bars ==

Sliders are also extensively combined with [[progress bar]]s in the playback of [[Internet video]] and [[Internet radio]] to allow the user the ability to shift to points within the media as far as the current extent of the download (which is indicated by the progress in the bar) will allow.

Sliders are also combined with [[progress bar]]s in the playback of [[streaming media]] over a network connection (e.g., YouTube videos) in order to show the content buffering position versus the playback position.{{citation needed|date=May 2025}} This is done by superimposing a colored shaded area (progress bar) on top of the slider, indicating whether the user can "jump" forward or not.
