Sure!

Example codes:

• Example at https://talk.maemo.org/showpost.php?...84&postcount=1
• More advanced showing how to add objects: https://github.com/rinigus/mapbox-gl...p/qml/main.qml
• Poor Maps port to this widget https://github.com/rinigus/poor-maps/tree/gl with map QML at https://github.com/rinigus/poor-maps...gl/qml/Map.qml

Vector maps are different from raster in the interactivity with them, you can insert/remove/modify your objects. So, API has to be richer than before.

To learn, I would suggest to

• Make an account at Mapbox, go to Mapbox Studio and try to edit one of their styles. Just play a little bit with it (10-15 min) to get the feeling of interaction between sources/layers/properties
• Take a brief look into https://www.mapbox.com/mapbox-gl-js/style-spec (10-15 min); later you will need to read sections on the need basis
• API for the widget is documented at https://github.com/rinigus/mapbox-gl.../master/api.md . Look through, you don't need every property/signal, just get a feeling
• Start hacking on the basis of examples
• Don't hesitate to ask for help.
