How I can create Json Format in Qt ?

npatil15

I have an example, but not getting how I can create it.

{
  "Version" : "1.0",
  "tap" : { },
  "notation" : {  },
  "definition" : 
     [
        {
          "tag":1,
          "Name" : "view1"
        }

        {
          "tag":2,
          "Name" : "view2"
        }
     ]
  "images" : 
     {
        "File" : "image.png",
        "Index" : 0,
        "Properties" : [ "black", "bold"]
     }
}

@npatil15 Please take a look at https://doc.qt.io/qt-5/json.html first
You will even find a link to an example there...

@npatil15 Sorry, I'm not going to write code for you to create exact the JSON document you want to write. Read documentation, take a look at axamples and think about hot to create such a JSON document.

Hi
As a starter.
To build a json document, you insert the various json types that make up the structure.

like

   QJsonDocument doc;

    QJsonObject root;
    QJsonObject someObj;
// create an array and put a double and object in it
    QJsonArray array;
    array.append( QJsonValue(32.4) );
    array.append( someObj );
// add some properties to the root object
    root["intValue"] = 1;
// add empty object
    root["SomeEmptyObject"] = someObj;
//add the array
    root["somearray"] = array;
// set to the document
    doc.setObject(root);
    qDebug().noquote().nospace() << doc.toJson();

{  
   "SomeEmptyObject":{  

   },
   "intValue":1,
   "somearray":[  
      32.4,
      {  

      }
   ]
}
