Not commenting on this API, but I’d like to note that the API I brought up as
“missing” from my use-case was a more “light weight” in-place edit API, where
the user does not have to define bindings to data structures like above.
Similar to e.g. python:
>>> data = json.loads('{ "foo": [1, 2, 3] }')
>>> data
{u'foo': [1, 2, 3]}
>>> data["foo"][0] = 42
>>> data
{u'foo': [42, 2, 3]}
With our existing APIs I’d expect:
QJsonDocument doc;
doc[“foo”][0] = 42;
