Accessing the QTabBar instance

How can I access the QTabBar QTabWidget ?

The only solution I have found is to subclass QTabWidget

and override protected QTabWidget::getTabBar()

as public. Is there any other way to do this?

As you mentioned, subclassing is the right solution as it is protected. Something like that:

class TabWidget : public QTabWidget {
public:
    TabWidget(QWidget *p = 0) : QTabWidget(p){}

public:
    QTabBar *tabBar() const { return QTabWidget::tabBar(); }
};


You can tell the designer to "promote" your QTabWiget to the TabWidget, then you have a function available tabBar()

.

What do you want to do in the tab bar?

May not help, but with stylesheets you can customize QTabWidget :: tab and :: tab-bar sub-controls.
