Detailed Description

\inmodule QtLocation \keyword QGeoJson Namespace

The QGeoJson namespace contains functions to import and export geolocated information from and to GeoJson files.

Since

5.13

The methods in the QGeoJson namespace can be used to convert between a GeoJSON document (see the \l {https://en.wikipedia.org/wiki/GeoJSON} {Wikipedia page}, \l {https://tools.ietf.org/html/rfc7946} {RFC}) and a \l QVariantList of \l QVariantMap elements ready to be used as Model in a \l MapItemView.

Note

This private class is part of Qt labs, thus not stable API, it is part of the experimental components of QtLocation. Until it is promoted to public API, it may be subject to source and binary-breaking changes.

exportGeoJson()

Q_LOCATION_PRIVATE_EXPORT QJsonDocument QGeoJson::exportGeoJson

(

const QVariantList &

geoData

)

This method exports the QVariantList geoData, expected to be structured like described in the section \l {Importing GeoJSON}, to a QJsonDocument containing the data converted to GeoJSON.

Note

This method performs no validation on the input.
