body: <p>I have:</p>
  <pre><code>QJsonObject obj1({&quot;bla&quot; : &quot;lab&quot;})
  QJsonObject obj2({&quot;bla2&quot; : &quot;lab2&quot;})
  </code></pre>
  <p>and I need:</p>
  <pre><code>QJsonObject obj3({&quot;bla&quot; : &quot;lab&quot;, &quot;bla2&quot; : &quot;lab2&quot;})
  </code></pre>
  <p>Or in JSON:</p>
  <pre><code>{
      &quot;bla&quot; : &quot;lab&quot;
  }
  
  {
      &quot;bla2&quot; : &quot;lab2&quot;
  }
  </code></pre>
  <p>And I need:</p>
  <pre><code>{
      &quot;bla&quot; : &quot;lab&quot;,
      &quot;bla2&quot; : &quot;lab2&quot;
  }
  </code></pre>
