Displaying a high number of qmlMapItems on map with Mapbox plugin



  • Hello everyone,
    I am trying to create display a large number (around 2000) of points on qml Map with mapbox plugin. The point positions should be updated regulary and I have the performance problem with very high amount of points but the problem isnt with updates but with points creation itself.

    Is it possible to have some many qmlMapItems on Map at the same time?

     Map {
              objectName: "Map"
              id:map
              anchors.fill: parent
              plugin: mapboxglPlugin
              center: QtPositioning.coordinate(30.0, 30.0) 
              zoomLevel: 14
              Component.onCompleted: {
                  MyScript.createPoints();
                }
    }
    
    function createPoints() {
        component = Qt.createComponent("mapCircle.qml");
        if (component.status === Component.Ready){
            finishCreation();
        }
        else
            component.statusChanged.connect(finishCreation);
    }
    
    function finishCreation() {
        if (component.status === Component.Ready) {
            for(var i = 0;i < 2000;i++){
                mcircle = component.createObject(map,{objectName:"MapCircle"+i});
                map.addMapItem(mcircle);
    
            }
    
            if (mcircle === null) {
                // Error Handling
                console.log("Error creating object");
            }
        } else if (component.status === Component.Error) {
            // Error Handling
            console.log("Error loading component:", component.errorString());
        }
    
    MapCircle{
        objectName:"MapCircle"
        id:circle
        radius: 50.0;
        color: "red"
        border.width:  3.0
        center{
            latitude: 30.0
            longitude: 30.0
        }
    }
