+ \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:
