How to pass ListModel data to C++ function

cmessineo

I have a ListModel in QML:

@
ListModel{
id: data
ListElement
{
x: 10
y: 20
count: 18
}
}

function draw(){
ctx.drawIntensityMap(data);
}

//********** 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++.

Thanks

Hi,

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