\brief A busy indicator.
\image qtquickcontrols2-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
You can create a custom appearance for a Busy Indicator by
assigning an item to the \l indicator property.
The default implementation uses this QML item as indicator:
\snippet BusyIndicator.qml indicator
