Constructor & Destructor Documentation

◆ QDeclarativeGeoJsonData()

QDeclarativeGeoJsonData::QDeclarativeGeoJsonData ( QObject * parent = nullptr )

explicit

\qmltype GeoJsonData \instantiates QDeclarativeGeoJsonData \inqmlmodule QtLocation

Since: QtLocation 6.7

A model to represent, load and save GeoJSON documents.

The GeoJsonData element reads and writes GeoJson documents (see the \l {https://en.wikipedia.org/wiki/GeoJSON} {Wikipedia page}, \l {https://tools.ietf.org/html/rfc7946} {RFC}) from the \l {sourceUrl}. The respective data can be accessed as \l {QVariant} via the \l {model} property. The \l {QVariant} representation can be used with delegates to visualize the data or to make small modifications, e.g. adding new items with the \l {addItem} function.

New data can be stored with the \l {save} and \l {saveAs} functions.
