Как получить координаты карты в Qt

Добрый день.
Пытаюсь получить координаты из карты, но программа их не возвращает.
Скажите пожалуйста, что не правильно и что нужно исправить, что бы получить координаты?

import QtQuick 2.12
import QtQuick.Window 2.12
import QtLocation 5.12
import QtPositioning 5.12

Item {
    visible: true
    width: 480
    height: 720

    property double old : 19
    property double now


    Rectangle
    {
        anchors.fill: parent
        color: "#eee"


        PositionSource
        {
            id: src
            active: true
            updateInterval: 1000
            onPositionChanged:
            {
                console.log("PositionSource:" )
            }
        }

        Plugin
        {
            id: plugin
            name: "osm"
            PluginParameter { name: "osm.useragent"; value: "My great Qt OSM application" }
            PluginParameter { name: "osm.mapping.host"; value: "http://osm.tile.server.address/" }
            PluginParameter { name: "osm.mapping.copyright"; value: "All mine" }
            PluginParameter { name: "osm.routing.host"; value: "http://osrm.server.address/viaroute" }
            PluginParameter { name: "osm.geocoding.host"; value: "http://geocoding.server.address" }
            PluginParameter { name: "osm.places.host"; value: "http://geocoding.server.address" }
        }

        Map
        {
            id: maps
            anchors.fill: parent
            plugin: plugin
            gesture.enabled: true
            gesture.acceptedGestures: MapGestureArea.PinchGesture | MapGestureArea.PanGesture | MapGestureArea.FlickGesture
            gesture.flickDeceleration: 3000
            zoomLevel: 19
            center: QtPositioning.coordinate(59.91, 10.75) // Oslo

            onZoomLevelChanged:
            {
                console.log("onZoomLevelChanged:")
            }

            onCenterChanged:
            {
                console.log("onCenterChanged:")
                console.log("coordinate:" + src.position.coordinate)
            }

            minimumZoomLevel: 1

            focus: true

        }
    }
}

Так можно найти центр.
Но как можно определить размеры видимой карты?

console.log("coordinate ctnter:" + visibleRegion.center())

    Так работает

                    console.log("coordinate ctnter:" + visibleRegion.center())
                    console.log("coordinate geoshape:" + visibleRegion.boundingGeoRectangle())
