QML ListModel is not a QML List Type

As 0 be 1 cannot be (from Star Wars parlance), a QML ListModel is not a list QML Basic Type. Given that said, let's say you have a properly populated ListModel of coordinates (i.e. pairs of latitude and longitude values), and you want to use it as input for a QML MapPolyline to display a polyline in a map...
Well, you cannot use your ListModel directly to the path property, as it expects a list of coordinates. In such case, you can "flatten" or convert the ListModel into the proper list. Tip: the magic happens in function Map.asList()

ListModel

{
 id: myListModel

 ListElement

 {

  latitude: -28.9

  longitude: 25.1

 }

 ListElement

 {

  latitude: -28.2

  longitude: 25.3

 }

 ListElement

 {

  latitude: -28.4

  longitude: 25.5

 }

 ListElement

 {

  latitude: -28.6

  longitude: 25.7

 }

}



...



Map {

 id: map

 anchors.fill: parent

 plugin: mapPlugin

 center: QtPositioning.coordinate(-28.2, 25.3)

 zoomLevel: 8

 function asList() {

  var list = []

  for(var i = 0; i < myListModel.count; ++i) {

   list.push(

          {

    latitude: myListModel.get(i).latitude,

    longitude: myListModel.get(i).longitude

   }

   );

  }

  return list

 }

        MapPolyline

        {

     id: assetsPolyline

            line.color: "blue"

            line.width: 3

            visible : true

            path : map.asList()

        }

}
