## Detailed Description

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:

      BusyIndicator {
          running: image.status === Image.Loading
      }

BusyIndicator is similar to an indeterminate 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:

- in the corner of a ToolBar
- as an overlay on top of a Page
- on the side of an ItemDelegate

## Property Documentation

running : bool

This property holds whether the busy indicator is currently indicating activity.

Note: The indicator is only visible when this property is set to `true`.

The default value is `true`.
