Creating json file with subroot

Christian Ehrlicher

What exactly did you try? It's a simply QJsonObject which contains an array of QJsonObjects.

@Christian-Ehrlicher
I have written a code like this but it does not work as i want

QJsonArray root;
QJsonObject route;
QJsonObject route_pt;

  route.insert(" no", 5);
  route.insert("starting pt", 7);
  route.insert("total pt", 3);
  root.append(route);

   route_pt.insert("latitude", 5);
   route_pt.insert("longitude", 3);
   route_pt.insert("no", 5);

   root.append(rota_nokta);
   QJsonDocument doc;
   doc.setArray(root);

Christian Ehrlicher

You forgot the Plan object

@Christian-Ehrlicher it already gives an error in the last line.

doc.setArray(root);

: no matching function for call to ‘QJsonDocument::setObject(QJsonArray&)’
    doc.setObject(root);
                      ^

This is not what you showed us above!

doc.setArray(root);

@Christian-Ehrlicher I mixed my code sorry.
I fixed my problem. Now it seems like: How should i add plan, and route and pt info headings

[
    {
        "starting pt": 7,
        "no": 5,
        "Total pt": 3
    },
    {
        "latitude": 3,
        "longitude": 5,
        "no": 5,

    }
]

I don't understand your question. Already told you that the array is in an object.

@Christian-Ehrlicher this is what i want to achieve:

{
    "Plan" : [
        { 
          "route":
             {
             "no" : 1.12,
             "Starting pt" : 1.19,
             "Total pt" :5
         },
          "pt info":
             {
              "latitude" : 30.42,
              "longitude" : 41.19,
              "no" :5
  
        }
       } 
    ]
}

And here is mine:

[
    {
        "starting pt": 7,
        "no": 5,
        "Total pt": 3
    },
    {
        "latitude": 3,
        "longitude": 5,
        "no": 5,

    }
]

They are so different from each other. I didnt understand, how can i set a root name like plan, or route and pt info. This is my question

This sentence helped me a lot (!)

What is so hard to understand?

QJsonObject plan;
plan.insert("Plan", root);
QJsonDocument doc(plan);
qDebug() << QString::fromLatin1(doc.toJson());

EDIT: it would be better to rename your QJsonArray object root to planArray and plan to root to better match with your json document structure

@KroMignon thank you
