# Indicator Controls

Qt Quick Controls offers a selection of indicator-like controls.

BusyIndicator | Indicates background activity, for example, while content is being loaded
PageIndicator | Indicates the currently active page
ProgressBar | Indicates the progress of an operation

Each type of indicator has its own specific target use case. The following sections offer guidelines for choosing the appropriate type of indicator, depending on the use case.
