Detailed Description▲
The QPlaceContentRequest class is used in conjunction with a QPlaceManager to retrieve rich content like images and reviews in a paginated fashion. The following code would request a set of 5 images from the 10th index:
QPlaceContentRequest request;
request.setContentType(QPlaceContent::ImageType);
request.setPlaceId(place.placeId());
request.setLimit(5);
QPlaceContentReply *contentReply = manager->getPlaceContent(request);
//..connect signals..//
...
...
void contentHandler() {
if (contentReply->error() == QPlaceReply::NoError) {
place.insertContent(contentReply->request().contentType(),
contentReply->content());
}

QString QPlaceContentRequest::placeId() const▲
void QPlaceContentRequest::setContentContext(const QVariant &context)▲
Sets the content context to context.
This method is intended to be used by geo service plugins when returning place content results.
The content context is used by backends to store additional content context related to the content request. Other relevant fields should also be filled in. For example, if the content request is for image content the content type should also be set with setContentType(). The content context allows additional context to be kept which is not directly accessible via the Qt Location API.
The content context can be of any type storable in a QVariant. The value of the content context is not intended to be used directly by applications.
