QML Mapbox "The geoservices provider is not supported"

vcasado

Dear Sirs,

I am trying to develop an app with an embedded map, and I want to use Mapbox, starting from the OSM example "Minimal Map".

The problem is that when I switch to Mapbox, i just receive "The geoservices provider is not supported"

The QML file that I have is:

import QtQuick
import QtLocation
import QtPositioning

Window {
    width: Qt.platform.os == "android" ? Screen.width : 512
    height: Qt.platform.os == "android" ? Screen.height : 512
    visible: true
    title: map.center + " zoom " + map.zoomLevel.toFixed(3)
           + " min " + map.minimumZoomLevel + " max " + map.maximumZoomLevel

    Map {
        id: map
        anchors.fill: parent
        center: QtPositioning.coordinate(-3.695233, 40.602505) // Bewatt
        zoomLevel: 24
        property geoCoordinate startCentroid

        plugin: Plugin {
            name: "mapbox"
            PluginParameter {
                name: "mapboxgl.mapping.cache.memory"
                value: true
            }
            PluginParameter {
                  name: "mapbox.access_token"
                  value: "XXXXX"
            }
            PluginParameter {
                  name: "osm.routing.host"
                  value: "https://valhalla1.openstreetmap.de/"
            }
            PluginParameter {
               name: "mapbox.mapping.highdpi_tiles"
               value: true
            }
        }

        PinchHandler {
            id: pinch
            target: null
            onActiveChanged: if (active) {
                map.startCentroid = map.toCoordinate(pinch.centroid.position, false)
            }
            onScaleChanged: (delta) => {
                map.zoomLevel += Math.log2(delta)
                map.alignCoordinateToPoint(map.startCentroid, pinch.centroid.position)
            }
            onRotationChanged: (delta) => {
                map.bearing -= delta
                map.alignCoordinateToPoint(map.startCentroid, pinch.centroid.position)
            }
            grabPermissions: PointerHandler.TakeOverForbidden
        }
        WheelHandler {
            id: wheel
            acceptedDevices: Qt.platform.pluginName === "cocoa" || Qt.platform.pluginName === "wayland"
                             ? PointerDevice.Mouse | PointerDevice.TouchPad
                             : PointerDevice.Mouse
            rotationScale: 1/120
            property: "zoomLevel"
        }
        DragHandler {
            id: drag
            target: null
            onTranslationChanged: (delta) => map.pan(-delta.x, -delta.y)
        }
        Shortcut {
            enabled: map.zoomLevel < map.maximumZoomLevel
            sequence: StandardKey.ZoomIn
            onActivated: map.zoomLevel = Math.round(map.zoomLevel + 1)
        }
        Shortcut {
            enabled: map.zoomLevel > map.minimumZoomLevel
            sequence: StandardKey.ZoomOut
            onActivated: map.zoomLevel = Math.round(map.zoomLevel - 1)
        }
    }

    RouteModel {
        id: routeModel

        autoUpdate: true
        query: routeQuery

        plugin: Plugin {
            name: "mapbox"

            // Development access token, do not use in production.
            PluginParameter {
                name: "mapbox.access_token"
                value: "XXXXXX"
            }
        }

        Component.onCompleted: {
            if (map) {
                map.updateRoute();
            }
        }
    }

    RouteQuery {
        id: routeQuery
    }
}

Thank you so much

I have exactly the same issue with Qt6.5.2,

Have you found some solution since the time you created the post ?

JKSH

Qt 6 will not support the Mapbox backend. See the section "Reducing the number of included backends" at https://www.qt.io/blog/the-road-to-qt-location
