The isFinished(), error() and errorString() methods provide information on whether the operation has completed and if it completed successfully. The finished() and error(QGeoSearchReply::Error,QString) signals can be used to monitor the progress of the operation. It is possible that a newly created QGeoSearchReply may be in a finished state, most commonly because an error has occurred. Since such an instance will never emit the finished() or error(QGeoSearchReply::Error,QString) signals, it is important to check the result of isFinished() before making the connections to the signals. The documentation for QGeoSearchManager demonstrates how this might be carried out. If the operation completes successfully the results will be able to be accessed with places(). */ /*! \enum QGeoSearchReply::Error Describes an error which prevented the completion of the operation. \value NoError No error has occurred. \value EngineNotSetError The search manager that was used did not have a QGeoSearchManagerEngine instance associated with it. \value CommunicationError An error occurred while communicating with the service provider. \value ParseError The response from the service provider was in an unrecognizable format. \value UnsupportedOptionError The requested operation or one of the options for the operation are not supported by the service provider. \value CombinationError An error occurred while results where being combined from multiple sources. \value UnknownError An error occurred which does not fit into any of the other categories. */ /*!
