\brief Indicates background activity, for example, while content is being loaded.
\image qtquickcontrols-busyindicator.gif
The busy indicator should be used to indicate activity while content is
being loaded or the UI is blocked waiting for a resource to become available.
The following snippet shows how to use the BusyIndicator:
\qml
BusyIndicator {
running: image.status === Image.Loading
}
\endqml
BusyIndicator is similar to an indeterminate \l ProgressBar. Both can be
used to indicate background activity. The main difference is visual, and
that ProgressBar can also present a concrete amount of progress (when it
can be determined). Due to the visual difference, busy indicators and
indeterminate progress bars fit different places in user interfaces.
Typical places for a busy indicator:
\list
\li in the corner of a \l ToolBar
\li as an overlay on top of a \l Page
\li on the side of an \l ItemDelegate
\endlist
