Sorting QML dictionary by key

• Apr 16, 2022 - 03:08

Apologies for asking here, but googling hasn't given me much joy, as it seems to be a mashup of javascript and dense QML documentation that doesn't seem to work quite right.

I have a dictionary that I've defined as "{}" in my QML code.
I want to iterate over the keys in this dictionary in order, either via a default sort or via a function that I define to sort by.

Is this something you can do, if so, how ? If there's documentation, I'd be happy to be pointed to that as well.

thanks,
John

In case anyone needs this in the future:

    function sortMapKeys(obj) {
        var arr = [];
        for (var prop in obj) {
            if (obj.hasOwnProperty(prop)) {
                arr.push(prop);
            }
        }
        arr.sort(function(a, b) { return a - b; });
        return arr;
    }

Well done!

By the way, the StackOverflow website is excellent for getting answers to these sort of questions.
