Cannot do addTab in loop for

[Lokl]

Hi everyone,

I want to instanciate as far as I want QWidget to push into QTabWidget.

QJsonArray jsonArray = jsonObject.value("Channel").toArray();
 
    for(int indexchannel(0); indexchannel < jsonArray.size(); indexchannel++){
        QString channel = jsonArray[indexchannel].toString();
//        m_console.push_back(new Console(channel));
        tab->addTab(new QWidget, channel);
        m_console.append(new Console(channel));
        onglet->setObjectName(QStringLiteral(channel));
        tab->addTab(console, console->channelName() );
    }
//    for (int widgetIndexChannel(0) ; widgetIndexChannel <m_console.size(); widgetIndexChannel++ ){
//        tab->addTab(m_console.at(widgetIndexChannel), m_console.at(widgetIndexChannel)->channelName());
//    }
    tab->addTab(new QWidget, "testttt");
    verticalLayout->addWidget(tab);
    this->setCentralWidget(centralWidget);

QJsonArray jsonArray = jsonObject.value("Channel").toArray();

    for(int indexchannel(0); indexchannel < jsonArray.size(); indexchannel++){
        QString channel = jsonArray[indexchannel].toString();
//        m_console.push_back(new Console(channel));
        tab->addTab(new QWidget, channel);
        m_console.append(new Console(channel));
        onglet->setObjectName(QStringLiteral(channel));
        tab->addTab(console, console->channelName() );
    }
//    for (int widgetIndexChannel(0) ; widgetIndexChannel <m_console.size(); widgetIndexChannel++ ){
//        tab->addTab(m_console.at(widgetIndexChannel), m_console.at(widgetIndexChannel)->channelName());
//    }
    tab->addTab(new QWidget, "testttt");
    verticalLayout->addWidget(tab);
    this->setCentralWidget(centralWidget);

To copy to clipboard, switch view to plain text mode 

according to a json file I populate my view. But I'm doing this in loop and nothing append. I feel like the addTab doesn't work in loop even though doesn't it use like that does it ?
Sorry for my poor question.
