How to pass ListModel data to C++ function

  • I have a ListModel in QML:

    id: data
    x: 10
    y: 20
    count: 18

    function draw(){

    //********** c++ code

    void Context2D::drawIntensityMap(QVariantList data)

    The model just gets populated with x,y,count data via javascript. After it gets populated I want to pass it to my c++ function so I can draw a HeatMap with QPainter.
    I can't figure out how to pass the data to my C++ function.

    Would I have to pass it as a QVariantList? If so how would I get to the data in C++.

    You can iterate and add the model data into an array and pass that array as QVariantList to the C++ function.
