\inmodule QtLocation
The QGeoTiledMapReply class manages a tile fetch operation started by an instance of QGeoTiledManagerEngine.
Instances of QGeoTiledMapReply 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 errorOccurred(QGeoTiledMapReply::Error,QString) signals can be used to monitor the progress of the operation.
It is possible that a newly created QGeoTiledMapReply may be in a finished state, most commonly because an error has occurred. Since such an instance will never emit the finished() or errorOccurred(QGeoTiledMapReply::Error,QString) signals, it is important to check the result of isFinished() before making the connections to the signals.
If the operation completes successfully the results are accessed by mapImageData() and mapImageFormat().
Definition at line 27 of file qgeotiledmapreply_p.h.
Describes an error which prevented the completion of the operation.
\value NoError No error has occurred. \value CommunicationError An error occurred while communicating with the service provider. \value ParseError The response from the service provider was in an unrecognizable format supported by the service provider. \value UnknownError An error occurred which does not fit into any of the other categories.

QGeoTiledMapReply::QGeoTiledMapReply | ( | const QGeoTileSpec & | spec, |
QObject * | parent = nullptr ) |
Constructs a tiled map reply object based on request, with parent parent.
Definition at line 59 of file qgeotiledmapreply.cpp.
QGeoTiledMapReply::QGeoTiledMapReply | ( | Error | error, |
const QString & | errorString, | ||
QObject * | parent = nullptr ) |
Constructs a tiled map reply object with a given error and errorString and the specified parent.
Definition at line 68 of file qgeotiledmapreply.cpp.
|
virtual |
Destroys this tiled map reply object.
Definition at line 75 of file qgeotiledmapreply.cpp.
|
virtual |
Cancels the operation immediately.
This will do nothing if the reply is finished.
Definition at line 208 of file qgeotiledmapreply.cpp.
|
signal |
QGeoTiledMapReply::Error QGeoTiledMapReply::error | ( | ) | const |
Returns the error state of this reply.
If the result is QGeoTiledMapReply::NoError then no error has occurred.
Definition at line 127 of file qgeotiledmapreply.cpp.
|
signal |
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::errorOccurred() will be emitted at the same time.
QString QGeoTiledMapReply::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 QGeoTiledMapReply::error() is equal to QGeoTiledMapReply::NoError.
Definition at line 142 of file qgeotiledmapreply.cpp.
|
signal |
This signal is emitted when this reply has finished processing.
If error() equals QGeoTiledMapReply::NoError then the processing finished successfully.
This signal and QGeoRoutingManager::finished() will be emitted at the same time.
bool QGeoTiledMapReply::isCached | ( | ) | const |
Returns whether the reply is coming from a cache.
Definition at line 150 of file qgeotiledmapreply.cpp.
bool QGeoTiledMapReply::isFinished | ( | ) | const |
Return true if the operation completed successfully or encountered an error which cause the operation to come to a halt.
Definition at line 102 of file qgeotiledmapreply.cpp.
QByteArray QGeoTiledMapReply::mapImageData | ( | ) | const |
Returns the tile image data.
Definition at line 174 of file qgeotiledmapreply.cpp.
QString QGeoTiledMapReply::mapImageFormat | ( | ) | const |
Returns the format of the tile image.
Definition at line 190 of file qgeotiledmapreply.cpp.
|
protected |
Sets whether the reply is coming from a cache to cached.
Definition at line 158 of file qgeotiledmapreply.cpp.
|
protected |
Sets the error state of this reply to error and the textual representation of the error to errorString.
This will also cause errorOccurred() and finished() signals to be emitted, in that order.
Definition at line 114 of file qgeotiledmapreply.cpp.
|
protected |
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, QGeoTiledMapReply::setMapImageData() should be called before this function. If an error occurred, QGeoTiledMapReply::setError() should be used instead.
Definition at line 91 of file qgeotiledmapreply.cpp.
|
protected |
Sets the tile image data to data.
Definition at line 182 of file qgeotiledmapreply.cpp.
Sets the format of the tile image to format.
Definition at line 198 of file qgeotiledmapreply.cpp.
QGeoTileSpec QGeoTiledMapReply::tileSpec | ( | ) | const |
Returns the request which corresponds to this reply.
