Constructor & Destructor Documentation

◆ QDeclarativeGeoJsonData()

QDeclarativeGeoJsonData::QDeclarativeGeoJsonData ( QObject * parent = nullptr )

explicit

\qmltype GeoJsonData \nativetype QDeclarativeGeoJsonData \inqmlmodule QtLocation

Since: QtLocation 6.7

A model to represent, load and save GeoJSON documents.

The GeoJsonData type reads and writes GeoJson formatted documents. GeoJsonData has functions to open and save the model at the URL set to the \l sourceUrl property. The loaded model is internally represented by QVariant and binds to the \l model property. Use \l{Models and Views in Qt Quick#View Delegates}{Delegates} to visualize the items in a view.

For information about GeoJSON, visit the \l{https://geojson.org/}{GeoJSON} website.
