Detailed Description
This type provides an interface for updating a location - for example, used by the LocationDisplay.
AbstractLocationDataSource is a class which can be customized to provide your own data source. To do this, you would create a CustomLocationDataSource and implement the start and stop callbacks in JavaScript.
The DefaultLocationDataSource provides a default implementation designed to work with the QML types:
- PositionSource
- Compass
