QGeoPositionInfoSource::createDefaultSource(this) Does not fire events ...

Ritchie

Hi,

I would like to use the "gpsd" damon on a ubuntu 17.04 system. The samples "weatherinfo" and "Satellitinfo" are working with the plugin "libqtposition_gpsd" without any problem.

But when I use my own program, then it does not fire any event in the defined functions. I placed a break point in the slots, which was never reached.

defines

private slots:
        void    positionUpdated(QGeoPositionInfo);
        void    positionError(QGeoPositionInfoSource::Error);
        void    updateTimeout(void);

Program code

void		SensorThread::positionUpdated(QGeoPositionInfo info)
{
        m_PositionInfo=info;
}
void    SensorThread::positionError(QGeoPositionInfoSource::Error   gpserror)
{
    qDebug() << gpserror;
}
void    SensorThread::updateTimeout(void)
{
    qDebug() << "Time out";
}

void SensorThread::run(void)
{
...
    m_ProgramInfo->writelog(tr("carclient"),tr("SensorThread"),tr("Info"),tr("Thread startup"));

    qt_Position = QGeoPositionInfoSource::createDefaultSource(this);

    if (qt_Position)
        {
        connect(qt_Position, SIGNAL(positionUpdated(QGeoPositionInfo)),this, SLOT(positionUpdated(QGeoPositionInfo)));
        connect(qt_Position, SIGNAL(error(QGeoPositionInfoSource::Error)),this, SLOT(positionError(QGeoPositionInfoSource::Error)));
        connect(qt_Position, SIGNAL(updateTimeout()),this, SLOT(updateTimeout()));

        qt_Position->setUpdateInterval(500);
        qt_Position->setPreferredPositioningMethods(QGeoPositionInfoSource::SatellitePositioningMethods);
        qt_Position->startUpdates();
        }
    else
        m_ProgramInfo->writelog(tr("carclient"),tr("SensorThread"),tr("Error"),tr("Could not create qt_Position Object"));


    qt_Position->requestUpdate();

...
}

Here is the output of the program during debug session

Debugging starts
&"warning: GDB: Failed to set controlling terminal: Unpassender IOCTL (I/O-Control) f\303\274r das Ger\303\244t\n"
Connected to gpsd
Created slave QBuffer(0x7fffd4006100)
Unpausing slave QBuffer(0x7fffd4006100)

How can I get closed to the problem ?

Best regards
R.

Hello all,

I just recode the use of the application instead of C++ to Quick Qt and
now I get the events.

Thanks
R.
