@kshegunov thnks for your response but my question is how do I add the values to my combo box???

kshegunov

Get the strings through the QJsonDocument (there are examples in the docs) and then use QComboBox::addItem to add them to the actual combo box.

@kshegunov well look at this,

void MainWindow::datainDaHouse2(QByteArray data)
{
//first
 qDebug()<< "Jason value" +data;
 QJsonDocument doc = QJsonDocument::fromJson(data);
    QJsonArray array = doc.array();
    QJsonObject object = array.at(0).toObject();
    QString code = object["LeaderCode"].toString();

        ui->comboBox_54->insertItem(3,code);
     //second
        qDebug()<< "InsertCode" +code;
}

well this is my current code and my output for qDebug is,
//first
"Jason value<pre>[\n {\n "LeaderCode": "GNL0001"\n },\n {\n "LeaderCode": "GNL0002"\n }\n]</pre>"
//second here where my output getting blank
"InsertCode"
So any suggestions ? And sorry if I'm wrong with the code ,I'm newbie .

Vineela

well these are the changes I've done now its working good

void MainWindow::datainDaHouse2(QByteArray data)
{
data = data.replace("<pre>", "").replace("</pre>", "");
 QJsonDocument doc = QJsonDocument::fromJson(data);
    QJsonArray array = doc.array();
    for(int i=0 ;i<array.size();i++){
    QJsonObject object = array.at(i).toObject();
    QString code = object["LeaderCode"].toString();
    ui->comboBox_54->insertItem(1,code);
        qDebug()<< "InsertCode" +code;

    }
}

thnk u for your response :)
