Detailed Description
The GeoJsonData element reads and writes GeoJson documents (see the Wikipedia page, RFC) from the sourceUrl. The respective data can be accessed as QVariant via the model property. The QVariant representation can be used with delegates to visualize the data or to make small modifications, e.g. adding new items with the addItem function.
New data can be stored with the save and saveAs functions.
See also QGeoJson.
