Creating a class that implements tabs and can be used as a "central widget" in QMainWindow

I want the central widget of my mainWindow class to be a QTabWidget. My plan is to create widgets that I want to put in the tabs as separate classes and add them to QTabWidget class and add the QtabWidget class itself as a central Widget to the mainWindow class.

To do this, how must I declare my tabWidget class ?

Should it be :

class centralTab : public QMainWindow
{

}

or 

class centralTab : public QDialog
{

}

Also, in the ctor, What should be used as the parent ?

Just create QMainWindow subclass:

class MainWindow : public QMainWindow
{
    Q_OBJECT
public:
     explicit MainWindow(QWidget *parent = 0);
//...
};

In constructor use addTab() method::

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent)
{
        QTabWidget *tabWidget = new QTabWidget(this);
        //some settings
        tabWidget->addTab(new QLabel("example1"), "General1");
        tabWidget->addTab(new QLabel("example2"), "General2");
        setCentralWidget(tabWidget);
}

Why QMainWindow? Because only QMainWindow has setCentralWidget() method;

You can add different widgets and set also icon to every tab, QLabel is just example.
