Progress indicator
- This article is about a concept in computing. You may be looking for the Genuine Progress Indicator metric in economics.
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 to provide the user with an estimate of how far through a task the system has progressed.
Examples of progress indicators
- 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.
