Detailed Description
This type provide a default implementation of the AbstractLocationDataSource interface. It is used by default by the LocationDisplay.
The DefaultLocationDataSource is designed to work with the Qt types:
Not all devices can determine their own location. Your app can check for location availability using supportedPositioningMethods property on the DefaultLocationDataSource::positionInfoSource property. This property is set to QGeoPositionInfoSource::NoPositioningMethods (0x0) when there is no position source.

[explicit] DefaultLocationDataSource::DefaultLocationDataSource (QObject *parent = nullptr)
Create a location data source object with an optional parent.
[override virtual noexcept] DefaultLocationDataSource::~DefaultLocationDataSource ()
Destructor.
QCompass *DefaultLocationDataSource::compass() const
Returns the QCompass used by this data source.
See also setCompass().
[override virtual protected slot] void DefaultLocationDataSource::onStart ()
Reimplements: AbstractLocationDataSource::onStart().
Reacts to start requests by starting the positionInfoSource and compass.
Note: You should not call this method directly - use start instead.
[override virtual protected slot] void DefaultLocationDataSource::onStop ()
Reimplements: AbstractLocationDataSource::onStop().
Reacts to stop requests by stopping the positionInfoSource and compass.
Note: You should not call this method directly - use stop instead.
QGeoPositionInfoSource *DefaultLocationDataSource::positionInfoSource () const
Returns the QGeoPositionInfoSource used by this data source.
The default positionInfoSource will be created with this DefaultLocationDataSource as its parent:
QGeoPositionInfoSource::createDefaultSource(QObject* parent)
See also setPositionInfoSource().
void DefaultLocationDataSource::setCompass (QCompass *compass)
Sets the QCompass used by this data source to compass.
See also compass().
void DefaultLocationDataSource::setPositionInfoSource (QGeoPositionInfoSource *positionInfoSource )
Sets the QGeoPositionInfoSource used by this data source to positionInfoSource.
