| \class QGeoRouteReply |
| \inmodule QtLocation |
| \ingroup QtLocation-routing |
| \since 5.6 |
| |
| \brief The QGeoRouteReply class manages an operation started by an instance |
| of QGeoRoutingManager. |
| |
| Instances of QGeoRouteReply manage the state and results of these |
| operations. |
| |
| The isFinished(), error() and errorString() methods provide information |
| on whether the operation has completed and if it completed successfully. |
| |
| The finished() and error(QGeoRouteReply::Error,QString) |
| signals can be used to monitor the progress of the operation. |
| |
| It is possible that a newly created QGeoRouteReply may be in a finished |
| state, most commonly because an error has occurred. Since such an instance |
| will never emit the finished() or |
| error(QGeoRouteReply::Error,QString) signals, it is |
| important to check the result of isFinished() before making the connections |
| to the signals. The documentation for QGeoRoutingManager demonstrates how |
| this might be carried out. |
| |
| If the operation completes successfully the results will be able to be |
| accessed with routes(). |
| */ |
| |
| /*! |
| \enum QGeoRouteReply::Error |
| |
| Describes an error which prevented the completion of the operation. |
| |
| \value NoError |
| No error has occurred. |
| \value EngineNotSetError |
| The routing manager that was used did not have a QGeoRoutingManagerEngine 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 UnknownError |
| An error occurred which does not fit into any of the other categories. |
