thanks,
i declared a new Metatype GPSSatellite with << and >> operators.
struct GPSSatellite
{
int ID;
bool InUse;
unsigned int Elevation;
unsigned int Azimuth;
unsigned int SNR;
};
Q_DECLARE_METATYPE(GPSSatellite);
Q_DECLARE_METATYPE(QList<GPSSatellite>);
They work fine with the dBus method GetSatellites().
QDBusMessage SatelliteReply;
SatelliteReply = GPSInterface->call("GetSatellites");
QList<GPSSatellite> satList = qdbus_cast<QList<GPSSatellite>
>(SatelliteReply.arguments()[0]);
my problem is that i can not connect to the SatellitesChanged signal like:
connect(GPSInterface, SIGNAL( SatellitesChanged(QDBusMessage) ) ,this, SLOT(
handleSatellitesChanged(QDBusMessage) ) );
I have tried many Types and every time there's the error like:
Object::connect: No such signal local::Merged::SatellitesChanged(QDBusMessage)
which Type / Metatype shoud i use here??

*******************************************************************
for Interested the my GPSSatellite operators:
QDBusArgument &operator<<(QDBusArgument &argument, const GPSSatellite &sat)
{
argument.beginStructure();
argument << sat.ID << sat.InUse << sat.Elevation << sat.Azimuth <<
sat.SNR;
argument.endStructure();
return argument;
}
const QDBusArgument &operator>>(const QDBusArgument &argument, GPSSatellite
&sat)
{
argument.beginStructure();
argument >> sat.ID >> sat.InUse >> sat.Elevation >> sat.Azimuth >>
sat.SNR;
argument.endStructure();
return argument;
}
and somewhere in code:
qDBusRegisterMetaType<GPSSatellite>();
qDBusRegisterMetaType<QList<GPSSatellite> >();
