MapItemView does not show Route

  • Hi,

    I was playing around with QtQuick Maps and stuff and tried to display a route on a Map. I was able to do basic things like displaying the Map, centering it on a specific coordinate, zooming it and so on without much trouble, but displaying a Route just won't work.

    As far as I understood the documentation, what I did should work. But the docs are not super detailed about this topic.

    I reduced my code to a minimal example, which should just display a small route in Berlin:

    import QtQuick 2.7
    import QtQuick.Controls 2.0
    import QtQuick.Layouts 1.0
    import QtLocation 5.3
    import QtPositioning 5.3
    ApplicationWindow {
    	visible: true
    	width: 1000
    	height: 700
    	Plugin {
    		id: thePlugin
    		name: "mapbox"
    		PluginParameter {
    			name: "mapbox.access_token"
    			value: "MY_PRIVATE_MAPBOX_KEY"
    		PluginParameter {
    			name: "mapbox.map_id"
    			value: "mapbox.mapbox-streets-v6"
    	Map {
    		id: theMap
    		plugin: thePlugin
    		anchors.fill: parent
    		zoomLevel: maximumZoomLevel - 2
    		center: QtPositioning.coordinate(52.5152725, 13.3774632)
    		RouteQuery {
    			id: rQuery
    		RouteModel {
    			id: rModel
    			plugin: thePlugin
    			query: rQuery
    		Component {
    			id: rDelegate
    			MapRoute {
    				route: routeData
    				line.color: "yellow"
    				line.width: 10
    				smooth: true
    		MapItemView {
    			model: rModel
    			delegate: rDelegate
    			Component.onCompleted: {
    				rQuery.addWaypoint(QtPositioning.coordinate(52.5152725, 13.3774632));
    				rQuery.addWaypoint(QtPositioning.coordinate(52.5196863, 13.4040609));
    				rQuery.travelModes = RouteQuery.PedestrianTravel;

    I'd be glad, if somebody could have a look and tell me what I'm doing wrong...
