Hi Roman,
Your qGeoService provider is on the stack and discarded at the end of
your constructor. The documentation for geocodingManager makes clear
that the pointer returned is owned by the provider, so I assume the
pointer becomes invalid. Try keeping a pointer to the provider as well
as the coder.
Hope that helps, Tony

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?
