QML Map drawing a "route"

[DBoosalis]

I have been using Qt 5.9's new Map API, with the Mapbox plugin. To date I have been drawing the track of a vehicles progress with a QMapPolyline. This works pretty good but I would really like to get a more professional look by painting the road that the vehicle has gone over.

I have looked at the Route functionality, but so far no luck (there is not a lot of documentation on this), does anyone have a suggestion on how to paint a track on a map that fills in the actual road

Any suggestions appreciated.

Thanks
David
