The - \l searchTerm and \l categories properties can be set to restrict the search results to - places matching those criteria. - - The PlaceSearchModel returns both sponsored and - \l {http://en.wikipedia.org/wiki/Organic_search}{organic search results}. Sponsored search - results will have the \c sponsored role set to true. - - \target PlaceSearchModel Roles - The model returns data for the following roles: - - \table - \header - \li Role - \li Type - \li Description - \row - \li type - \li enum - \li The type of search result. - \row - \li title - \li string - \li A string describing the search result. - \row - \li icon - \li PlaceIcon - \li Icon representing the search result. - \row - \li distance - \li real - \li Valid only when the \c type role is \c PlaceResult, the distance to the place - from the center of the \l searchArea. If no \l searchArea - has been specified, the distance is NaN. - \row - \li place - \li \l Place - \li Valid only when the \c type role is \c PlaceResult, an object representing the - place. - \row - \li sponsored - \li bool - \li Valid only when the \c type role is \c PlaceResult, true if the search result is a - sponsored result. - \endtable - - \section2 Search Result Types - - The \c type role can take on the following values: - - \table - \row - \li PlaceSearchModel.UnknownSearchResult - \li The contents of the search result are unknown. - \row - \li PlaceSearchModel.PlaceResult - \li The search result contains a place. - \row - \li PlaceSearchModel.ProposedSearchResult - \li The search result contains a proposed search which may be relevant. - \endtable - - - It can often be helpful to use a \l Loader to create a delegate - that will choose different \l {Component}s based on the search result type. - - \snippet declarative/places_loader.qml Handle Result Types - - \section1 Detection of Updated and Removed Places - - The PlaceSearchModel listens for places that have been updated or removed from its plugin's backend. - If it detects that a place has been updated and that place is currently present in the model, then - it will call \l Place::getDetails to refresh the details. If it detects that a place has been - removed, then correspondingly the place will be removed from the model if it is currently - present. - - \section1 Example - - The following example shows how to use the PlaceSearchModel to search for Pizza restaurants in - close proximity of a given position. A \l searchTerm and \l searchArea are provided to the model - and \l update() is used to perform a lookup query. Note that the model does not incrementally - fetch search results, but rather performs a single fetch when \l update() is run. The \l count - is set to the number of search results returned during the fetch. - - \snippet places_list/places_list.qml Imports - \codeline - \snippet places_list/places_list.qml PlaceSearchModel - - \sa CategoryModel, {QPlaceManager} - - \section1 Paging - The PlaceSearchModel API has some limited support - for paging. The \l nextPage() and \l previousPage() functions as well as - the \l limit property can be used to access - paged search results. When the \l limit property is set - the search result page contains at most \l limit entries (of type place result). - For example, if the backend has 5 search results in total - [a,b,c,d,e], and assuming the first page is shown and limit of 3 has been set - then a,b,c is returned. The \l nextPage() would return d,e. The - \l nextPagesAvailable and \l previousPagesAvailable properties - can be used to check for further pages. At the moment the API does not - support the means to retrieve the total number of items available from the - backed. Note that support for \l nextPage(), previousPage() and \l limit can vary - according to the \l plugin. -*/ - -/*! - \qmlproperty Plugin PlaceSearchModel::plugin - - This property holds the \l Plugin which will be used to perform the search. -*/ - -/*! - \qmlproperty Plugin PlaceSearchModel::favoritesPlugin - - This property holds the \l Plugin which will be used to search for favorites. - Any places from the search which can be cross-referenced or matched - in the favoritesPlugin will have their \l {Place::favorite}{favorite} property - set to the corresponding \l Place from the favoritesPlugin. - - If the favoritesPlugin is not set, the \l {Place::favorite}{favorite} property - of the places in the results will always be null. - - \sa Favorites -*/ - -/*! - \qmlproperty VariantMap PlaceSearchModel::favoritesMatchParameters - - This property holds a set of parameters used to specify how search result places - are matched to favorites in the favoritesPlugin. - - By default the parameter map is empty and implies that the favorites plugin - matches by \l {Alternative Identifier Cross-Referencing}{alternative identifiers}. Generally, - an application developer will not need to set this property. - - In cases where the favorites plugin does not support matching by alternative identifiers, - then the \l {Qt Location#Plugin References and Parameters}{plugin documentation} should - be consulted to see precisely what key-value parameters to set. -*/ - -/*! - \qmlproperty variant PlaceSearchModel::searchArea - - This property holds the search area.
