    Hello,
    I have subclassed QTabWidget. Added two tabs.

    addTab(new QLineEdit, "Test1");
    addTab(new QWidget,"Test2");
    connect(this,&QTabWidget::tabBarClicked, this, [=](int i){qDebug()<<QString::number(i);} );
    

    Problem is that I cannot switch to the other tab and I can't insert any text in the QLineEdit object. The behaviour is like a picture. You can see the tabs and the QLineEdit instance, but you are not able to interact with any instance.

      I have subclassed QTabWidget.

      Why do you subclassed it?

      Please show us more code, there is no picture.

        Hi,
        I could solve the problem.

        ui->setupUi(this);
        

        This command should the first command in the constructor. I have placed it after the declaration and definition of the tab widget. That was the reason why it didn'tr run properly.
