QGeoCodeReply Class

Member Function Documentation

QGeoCodeReply::QGeoCodeReply(QGeoCodeReply::Error error, const QString &errorString, QObject *parent = nullptr)

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

[protected] QGeoCodeReply::QGeoCodeReply(QObject *parent = nullptr)

Constructs a geocode reply with the specified parent.

[virtual] QGeoCodeReply::~QGeoCodeReply()

Destroys this reply object.

[virtual] void QGeoCodeReply::abort()

Cancels the operation immediately.

This will do nothing if the reply is finished.

See also aborted().

[signal] void QGeoCodeReply::aborted()

This signal is emitted when the operation has been cancelled.

This function was introduced in Qt 5.9.

See also abort().

[protected] void QGeoCodeReply::addLocation(const QGeoLocation &location)

Adds location to the list of locations in this reply.

QGeoCodeReply::Error QGeoCodeReply::error() const

Returns the error state of this reply.

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

See also setError().

[signal] void QGeoCodeReply::error(QGeoCodeReply::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 QGeoCodingManager::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 signal by using the function pointer syntax, Qt provides a convenient helper for obtaining the function pointer as shown in this example:

connect(geoCodeReply, QOverload<QGeoCodeReply::Error, const QString &>::of(&QGeoCodeReply::error),
    [=](QGeoCodeReply::Error error, const QString &errorString){ /* ... */ });

QString QGeoCodeReply::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 QGeoCodeReply::error() is equal to QGeoCodeReply::NoError.

[signal] void QGeoCodeReply::finished()

This signal is emitted when this reply has finished processing.

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

This signal and QGeoCodingManager::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 QGeoCodeReply::isFinished() const

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

int QGeoCodeReply::limit() const

Returns the limit on the number of responses from each data source.

If no limit was set this function will return -1.

This may be more than locations().length() if the number of responses was less than the number requested.

See also setLimit().

QList<QGeoLocation> QGeoCodeReply::locations() const

Returns a list of locations.

The locations are the results of the operation corresponding to the QGeoCodingManager function which created this reply.

See also setLocations().

int QGeoCodeReply::offset() const

Returns the offset into the entire result set at which to start fetching results.

See also setOffset().

[protected] void QGeoCodeReply::setError(QGeoCodeReply::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 QGeoCodeReply::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, QGeoCodeReply::setLocations() should be called before this function. If an error occurred, QGeoCodeReply::setError() should be used instead.

See also finished().

[protected] void QGeoCodeReply::setLimit(int limit)

Sets the limit on the number of responses from each data source to limit.

If limit is -1 then all available responses will be returned.

See also limit().

[protected] void QGeoCodeReply::setLocations(const QList<QGeoLocation> &locations)

Sets the list of locations in the reply.

See also locations().

[protected] void QGeoCodeReply::setOffset(int offset)

Sets the offset in the entire result set at which to start fetching result to offset.

See also offset().

[protected] void QGeoCodeReply::setViewport(const QGeoShape &viewport)

Sets the viewport which contains the results to viewport.

See also viewport().

QGeoShape QGeoCodeReply::viewport() const

Returns the viewport which contains the results.

This function will return 0 if no viewport bias was specified in the QGeoCodingManager function which created this reply.

See also setViewport().
