Hello Paolo,
Thanks for reply.
I use it so:
In the constructor I connect the signal from the geocoding manager
m_pGeoPositionUpdates = QGeoPositionInfoSource::createDefaultSource(this);
connect(m_pGeoPositionUpdates, &QGeoPositionInfoSource::positionUpdated, this,
&MyClass::onPositionUpdated);
QGeoServiceProvider qGeoService("osm");
m_pQGeoCoder = qGeoService.geocodingManager();
m_pGeoPositionUpdates->startUpdates();
In the connected slot I will do this :
void MyClass::onPositionUpdated(const QGeoPositionInfo &positionUpdate) {
// QGeoLocation location;
// location.setCoordinate(positionUpdate.coordinate());
// QGeoAddress address(location.address());
// updateGeoAddress(address);
qDebug() << "Is Coord Valid: " << positionUpdate.coordinate().isValid();
qDebug() << "Coordinate: " << positionUpdate.coordinate();
if (m_pQGeoCoder) {
QGeoCodeReply *pQGeoCode =
m_pQGeoCoder->reverseGeocode(positionUpdate.coordinate()); // CRASH
if (pQGeoCode) {
connect(pQGeoCode, &QGeoCodeReply::finished, [=]() {
if (pQGeoCode->error() == QGeoCodeReply::NoError) {
const QList<QGeoLocation> qGeoLocs = pQGeoCode->locations();
if (qGeoLocs.size() > 0) {
updateGeoAddress(qGeoLocs.first().address()); // This
function handles the received address
}
}
else {
qDebug() << pQGeoCode->errorString();
}
});
}
}
}
Thanks in advance
Regards
Roman

Hi, is the reply finished? do you get it from the finished signal of the
manager?
Or are you trying to use what the method returns you immediately?
