## Detailed Description

A QPlaceContent holds rich content such as images, reviews, or editorials, as well as attributes about the content such as the user or supplier of the content. Content objects might hold multiple data, e.g. an item holding a review typically includes the user that wrote the review. Use type() to inspect the type of content a QPlaceContent object represents, and dataTags() to see which data is held. Use value() to get the individual data as a QVariant.

Note: Some providers may require that the attribution string be displayed to the user whenever a piece of content is viewed.

The rich content of a place is typically made available as paginated items.

At present the QPlaceContent class is not extensible by 3rd parties.

Note: The Places API considers content objects to be 'retrieve-only' objects. Submission of content to a provider is not a supported use case.

## Member Type Documentation

### QPlaceContent::Collection

Synonym for QMap<int, QPlaceContent>. The key of the map is an `int` representing the index of the content. The value is the content object itself.

The `Collection` is intended to be a container where content items, that have been retrieved as pages, can be stored. This enables a developer to skip pages, for example indexes 0-9 may be stored in the collection, if the user skips to indexes 80-99, these can be stored in the collection as well.

### enum QPlaceContent::DataTag
