详细描述

A list of search results can be retrieved from the QPlaceSearchReply after it has successfully completed the request. Common to all search results are the title and icon , which can be used to present the search result to the user.

The intended usage is that depending on the type , the search result can be converted to a more detailed subclass like so:

if (result.type() == QPlaceSearchResult::PlaceResult) {
    QPlaceResult placeResult = result;
    qDebug() << placeResult.place().name();
    qDebug() << placeResult.place().location().coordinate();
    qDebug() << placeResult.distance();
}

The implementation is handled in such a way that object slicing is not an issue. It is not expected that client applications or backend plugins instantiate a QPlaceSearchResult directly, but rather client applications simply convert to search result subclasses and backend plugins only instantiate subclasses.
