QGeoRouteReply::QGeoRouteReply(Error error, const QString &errorString, QObject *parent = Q_NULLPTR)

Constructs a route reply with a given error and errorString and the specified parent.

[protected] QGeoRouteReply::QGeoRouteReply(const QGeoRouteRequest &request, QObject *parent = Q_NULLPTR)

Constructs a route reply object based on request, with the specified parent.

[virtual] QGeoRouteReply::~QGeoRouteReply()

Destroys this route reply object.

[virtual] void QGeoRouteReply::abort()

Cancels the operation immediately.

This will do nothing if the reply is finished.

[protected] void QGeoRouteReply::addRoutes(const QList<QGeoRoute> &routes)

Appends the list of routes to the existing list.

Error QGeoRouteReply::error() const

Returns the error state of this reply.

If the result is QGeoRouteReply::NoError then no error has occurred.

See also setError().

[signal] void QGeoRouteReply::error(QGeoRouteReply::Error error, const QString &errorString = QString())

This signal is emitted when an error has been detected in the processing of this reply. The 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.

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

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

Note: Signal error is overloaded in this class. To connect to this one using the function pointer syntax, you must specify the signal type in a static cast, as shown in this example:

connect(geoRouteReply, static_cast<void(QGeoRouteReply::*)(QGeoRouteReply::Error, const QString &)>(&QGeoRouteReply::error),
    [=](QGeoRouteReply::Error error, const QString &errorString){ /* ... */ });

QString QGeoRouteReply::errorString() const

Returns the textual representation of the error state of this reply.

If no error has occurred this will return an empty string. It is possible that an error occurred which has no associated textual representation, in which case this will also return an empty string.

To determine whether an error has occurred, check to see if QGeoRouteReply::error() is equal to QGeoRouteReply::NoError.

[signal] void QGeoRouteReply::finished()

This signal is emitted when this reply has finished processing.

If error() equals QGeoRouteReply::NoError then the processing finished successfully.

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

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

See also setFinished().

bool QGeoRouteReply::isFinished() const

Return true if the operation completed successfully or encountered an error which cause the operation to come to a halt.

QGeoRouteRequest QGeoRouteReply::request() const

Returns the route request which specified the route.

QList<QGeoRoute> QGeoRouteReply::routes() const

Returns the list of routes which were requested.

See also setRoutes().

[protected] void QGeoRouteReply::setError(Error error, const QString &errorString)

Sets the error state of this reply to error and the textual representation of the error to errorString.

This will also cause error() and finished() signals to be emitted, in that order.

See also error().

[protected] void QGeoRouteReply::setFinished(bool finished)

Sets whether or not this reply has finished to finished.

If finished is true, this will cause the finished() signal to be emitted.

If the operation completed successfully, QGeoRouteReply::setRoutes() should be called before this function. If an error occurred, QGeoRouteReply::setError() should be used instead.

See also finished().

[protected] void QGeoRouteReply::setRoutes(const QList<QGeoRoute> &routes)

Sets the list of routes in the reply to routes.

See also routes().
