QPlaceManager Class

 //1) Make an appropriate request
 QPlaceSearchRequest searchRequest;
 searchRequest.setSearchTerm("ice cream");
 searchRequest.setSearchArea(QGeoBoundingCircle(QGeoCoordinate(12.34, 56.78)));

 //2) Use the manager to initiate a request and retreive a reply object
 QPlaceSearchReply * searchReply = manager->search(searchRequest);

 //3) Connect the reply object to a slot which is invoked upon operation completion
 connect(searchReply, SIGNAL(finished()), this, SLOT(processSearchReply()));
     ...
     ...
 //4) Have the slot appropriately process the results of the operation
 void processSearchReply() {
     if (searchReply->error() == QPlaceReply::NoError) {
         foreach (const QPlaceSearchResult &result, searchReply->results()) {
             if (result.type() == QPlaceSearchResult::PlaceResult)
                 qDebug() << "Name:" << result.place().name();
         }
     }

 //5) Discard the rely object when done.
     searchReply->deleteLater();
     searchReply = 0;
 }

Member Function Documentation

QPlaceManager::~QPlaceManager()

Destroys the manager. This destructor is used internally by QGeoServiceProvider and should never need to be called in application code.

QPlaceCategory QPlaceManager::category(const QString & categoryId) const

Returns the category corresponding to the given categoryId.

void QPlaceManager::categoryAdded(const QPlaceCategory & category, const QString & parentId) [signal]

This signal is emitted if a category has been added to the manager's datastore. The parent of the category is specified by parentId.

This signal is only emitted by managers that support the QPlaceManager::NotificationsFeature.

void QPlaceManager::categoryRemoved(const QString & categoryId, const QString & parentId) [signal]

This signal is emitted when the category corresponding to categoryId has been removed from the manager's datastore. The parent of the removed category is specified by parentId.

This signal is only emitted by managers that support the QPlaceManager::NotificationsFeature.

void QPlaceManager::categoryUpdated(const QPlaceCategory & category, const QString & parentId) [signal]

This signal is emitted if a category has been modified in the manager's datastore. The parent of the modified category is specified by parentId.

This signal is only emitted by managers that support the QPlaceManager::NotificationsFeature.

QList<QPlaceCategory> QPlaceManager::childCategories(const QString & parentId = QString()) const

Returns a list of categories that are children of the category corresponding to parentId. If parentId is empty, all the top level categories are returned.

QStringList QPlaceManager::childCategoryIds(const QString & parentId = QString()) const

Returns the child category identifiers of the category corresponding to parentId. If parentId is empty then all top level category identifiers are returned.

QPlace QPlaceManager::compatiblePlace(const QPlace & original)

Returns a pruned or modified version of the original place which is suitable to be saved into this manager.

Only place details that are supported by this manager is present in the modified version. Manager specific data such as the place id, is not copied over from the original.

void QPlaceManager::error(QPlaceReply * reply, QPlaceReply::Error error, const QString & errorString = QString()) [signal]

This signal is emitted when an error has been detected in the processing of reply. The QPlaceManager::finished() signal will probably follow.

The error will be described by the error code error. If errorString is not empty it will contain a textual description of the error meant for developers and not end users.

This signal and QPlaceReply::error() will be emitted at the same time.

Note: Do not delete the reply object in the slot connected to this signal. Use deleteLater() instead.

void QPlaceManager::finished(QPlaceReply * reply) [signal]

This signal is emitted when reply has finished processing.

If reply->error() equals QPlaceReply::NoError then the processing finished successfully.

This signal and QPlaceReply::finished() will be emitted at the same time.

Note: Do not delete the reply object in the slot connected to this signal. Use deleteLater() instead.

QPlaceContentReply * QPlaceManager::getPlaceContent(const QString & placeId, const QPlaceContentRequest & request) const

Retrieves content for the place corresponding to placeId, according to the parameters specified in request.

See Fetching Rich Content for an example of usage.

QPlaceDetailsReply * QPlaceManager::getPlaceDetails(const QString & placeId) const

Retrieves a details of place corresponding to the given placeId.

See Fetching Place Details for an example of usage.

QPlaceReply * QPlaceManager::initializeCategories()

Initializes the categories of the manager.

See Using Categories for an example of usage.

QList<QLocale> QPlaceManager::locales() const

Returns a list of preferred locales. The locales are used as a hint to the manager for what language place and category details should be returned in.

If the first specified locale cannot be accommodated, the manager falls back to the next and so forth. Some manager backends may not support a set of locales which are rigidly defined. An arbitrary example is that some places in France could have French and English localizations, while certain areas in America may only have the English localization available. In this example, the set of supported locales is context dependent on the search location.

If the manager cannot accommodate any of the preferred locales, the manager falls back to using a supported language that is backend specific.

Support for locales may vary from provider to provider. For those that do support it, by default, the global default locale is set as the manager's only locale.

For managers that do not support locales, the locale list is always empty.

See also setLocales().

QString QPlaceManager::managerName() const

Returns the name of the manager

int QPlaceManager::managerVersion() const

Returns the manager version.

QPlaceMatchReply * QPlaceManager::matchingPlaces(const QPlaceMatchRequest & request) const

Returns a reply which contains a list of places which correspond/match those specified in the request. The places specified in the request come from a different manager.

QString QPlaceManager::parentCategoryId(const QString & categoryId) const

Returns the parent category identifier of the category corresponding to categoryId.

void QPlaceManager::placeAdded(const QString & placeId) [signal]

This signal is emitted if a place has been added to the manager engine's datastore. The particular added place is specified by placeId.

This signal is only emitted by managers that support the QPlaceManager::NotificationsFeature.

void QPlaceManager::placeRemoved(const QString & placeId) [signal]

This signal is only emitted by managers that support the QPlaceManager::NotificationsFeature.

QPlaceSearchReply * QPlaceManager::recommendations(const QString & placeId, const QPlaceSearchRequest & request = QPlaceSearchRequest()) const

Provides recommendations for places that are similar to the place identified by placeId, and using the parameters as specified in request.

See Recommendations for an example of usage.

QPlaceIdReply * QPlaceManager::removeCategory(const QString & categoryId)

Removes the category corresponding to categoryId from the manager.

See Removing a category for an example of usage.

QPlaceIdReply * QPlaceManager::removePlace(const QString & placeId)
