Hi all,
I have a problem because I use the Location api for found latitude and longitude, this is my constructor:

@
GeoLocalizzazione::GeoLocalizzazione()
{
_updateArrived = false;
_locationInfo = QGeoPositionInfoSource::createDefaultSource(this);
qDebug() << "Metodi supportati: " << (int)(_locationInfo->supportedPositioningMethods());
_locationInfo->setPreferredPositioningMethods(QGeoPositionInfoSource::AllPositioningMethods);
QObject::connect(_locationInfo, SIGNAL(positionUpdated(QGeoPositionInfo)), this, SLOT(positionUpdated(QGeoPositionInfo)));
QObject::connect(_locationInfo, SIGNAL(updateTimeout()), this, SLOT(updateTimeout()));
//_locationInfo->setUpdateInterval(1000);
_locationInfo->requestUpdate(5000);
_locationInfo->startUpdates();
qDebug() << "requestUpdates";
QTimer::singleShot(30000, this, SLOT(timerExpired()));
}@

the log of debug are this:

@Object::connect: No such slot QWidget::positionUpdated(QGeoPositionInfo) in ..\GamberoRosso\GeoLocalizzazione\geolocalizzazione.cpp:12
Object::connect: No such slot QWidget::updateTimeout() in ..\GamberoRosso\GeoLocalizzazione\geolocalizzazione.cpp:13
requestUpdates
Object::connect: No such slot QWidget::timerExpired() in ..\GamberoRosso\GeoLocalizzazione\geolocalizzazione.cpp:18@

but this is my h file:

@
QTM_USE_NAMESPACE;

namespace Ui {
class GeoLocalizzazione;
}

class GeoLocalizzazione : public QWidget
{

public:
GeoLocalizzazione();

private:

//DICHIARAZIONE VARIABILI
QString globalNavigation;
QGeoPositionInfoSource* _locationInfo;
bool _updateArrived;

protected slots:

void timerExpired();
void updateTimeout();
void positionUpdated(QGeoPositionInfo geoPositionInfo);

};
@

why not get the slots?

Add the Q_OBJECT macro to your GeoLocalizzazione class definition. Moc needs that to process signals and slots correctly.

You may want to add the Q_OBJECT macro in your class definition.
@
class GeoLocalizzazione : public QWidget
{
Q_OBJECT

public:
GeoLocalizzazione();

private:

//DICHIARAZIONE VARIABILI
QString globalNavigation;
QGeoPositionInfoSource* _locationInfo;
bool _updateArrived;

protected slots:

void timerExpired();
void updateTimeout();
void positionUpdated(QGeoPositionInfo geoPositionInfo);

};

[edit] a couple of seconds late :-(

Or select a Qt baseclass for your class from the new class dialog and have Creator do it for you :)

Note that you probably want to re-run qmake as well, after adding the Q_OBJECT macro.
