[Interest] Can QML model specify a range including negative numbers? For example -180 to +180 ?

[Daniel França]

If it's a sequential model you can:

1. Add the interval number as the model, and subtract the number you want.
model: 360

*Then:*
model -= 180

2. Create a javascript function to fill it:
function makeList(model){
     for (var x=-180; x <= 180; x++) {

        model.append({"value":x});

     }}
