Detailed Description

Rich content such as images, reviews and editorials inherit from the QPlaceContent class which contains common properties such as an attribution string and content contributor, which may take the form of a user and/or supplier. It is possible that a user from a supplier is contributing content, hence both fields could be filled in simultaneously.

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

Conversion between QPlaceContent and it's subclasses can be easily performed without casting. Due to the way it has been implemented, object slicing is not an issue, the following code is valid:

QPlaceImage image;

QPlaceContent content = image;

QPlaceImage image2;
image2 = content;
qDebug() << image2.url(); //image2.url() == "www.example.com"

The rich content of a place is typically made available as paginated items. The ability to convert between QPlaceContent and it's subclasses means that code which handles the mechanics of paging can be easily shared for each of the sub types.

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


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::Type

Defines the type of content.

Constant Value Description
QPlaceContent::NoType 0 The content object is default constructed, any other content type may be assigned to this content object
QPlaceContent::ImageType 1 The content object is an image
QPlaceContent::ReviewType 2 The content object is a review
QPlaceContent::EditorialType 3 The content object is an editorial
QPlaceContent::CustomType 0x0100 The content object is of a custom type

void QPlaceContent::setUser(const QPlaceUser &user)

Sets the user who contributed this content.

See also user().

QPlaceSupplier QPlaceContent::supplier() const

Returns the supplier who contributed this content.

See also setSupplier().

QPlaceContent::Type QPlaceContent::type() const

Returns the content type.

QPlaceUser QPlaceContent::user() const
