Progress indicator

Progress indicator

A progress indicator is an element of a command line interface, a textual user interface, or a graphical user interface that is intended to inform the user that an operation is in progress, to reassure that the system is not hung or waiting for user input,and often to provide the user with an estimate of how far through a task the system has progressed.

Examples of progress indicators

* The progress bar.
* The throbber.
* The splash screen.
* The hourglass mouse cursor.
* The spinning wait cursor.
* The startup window for KDE is a graphical user interface progress indicator, with the icons along the bottom of the window changing appearance as each part of the startup procedure is executed.
* The textual user interface versions of the PKZIP and RAR utilities display a running percentage as individual files are compressed.
