| 72 | |
| 73 | \brief The QPlaceContent class serves as the base class for rich content types. |
| 74 | |
| 75 | Rich content such as \l {QPlaceImage}{images}, \l {QPlaceReview}{reviews} |
| 76 | and \l {QPlaceEditorial}{editorials} inherit |
| 77 | from the QPlaceContent class which contains common properties such as |
| 78 | an attribution string and content contributor, which may take the form of a |
| 79 | \l {QPlaceUser}{user} and/or \l {QPlaceSupplier}{supplier}. It is possible that |
| 80 | a user from a supplier is contributing content, hence both fields could |
| 81 | be filled in simultaneously. |
| 82 | |
| 83 | \b {Note:} Some providers may \e {require} that the attribution string be displayed |
| 84 | to the user whenever a piece of content is viewed. |
| 85 | |
| 86 | Conversion between QPlaceContent and it's subclasses can be easily performed without |
| 87 | casting. Due to the way it has been implemented, object slicing is not an issue, |
| 88 | the following code is valid: |
| 89 | \snippet places/requesthandler.h Content conversion |
| 90 | |
| 91 | The rich content of a place is typically made available as paginated items. The ability |
| 92 | to convert between QPlaceContent and it's subclasses means that code which handles |
| 93 | the mechanics of paging can be easily shared for each of the sub types. |
| 94 | |
| 95 | At present the QPlaceContent class is not extensible by 3rd parties. |
| 96 | |
| 97 | Note: The Places API considers content objects to be 'retrieve-only' objects. |
| 98 | Submission of content to a provider is not a supported use case. |

| 103 | \typedef QPlaceContent::Collection |
| 104 | Synonym for QMap<int, QPlaceContent>. The key of the map is an \c int representing the |
| 105 | index of the content. The value is the content object itself. |
| 106 | |
| 107 | The \c {Collection} is intended to be a container where content items, that have been retrieved |
| 108 | as pages, can be stored. This enables a developer to skip pages, for example indexes 0-9 may be |
| 109 | stored in the collection, if the user skips to indexes 80-99, these can be stored in the |
| 110 | collection as well. |
