Add support for JS arrays in ListModel

    XMLWordPrintable

Details

    Description

      It would be very convenient to have a JSON data model to use with QML's list view elements, instead of emulating a model using XMLHttpRequest, regular JavaScript JSON support and ListModel. For example,

      Item {
    ListModel { id: listmodel }
    onCompleted: {
        var xhr = new XMLHttpRequest;
        xhr.open("GET", "http://service.com/api");
        xhr.onreadystatechange = function() {
            if (xhr.readyState == XMLHttpRequest.DONE) {
                var a = JSON.parse(xhr.responseText);
                for (var b in a) {
                    var o = a[b];
                    listmodel.append({name: o.name, url: o.url});
                }
            }
        }
        xhr.send();
    }
}
