Accessing to QTabBar instance

Question

Hi folks,

How I can acquire access to QTabBar of QTabWidget ? Through searching in docs and internet, I've found only solution: subclassing QTabWidget, and in some way giving public access to QTabBar instance (QTabWidget::getTabBar() has "protected" access modifier). Is there any other solution ?

Answer 1

tabBar->findChild<QTabBar *>(QLatin1String("qt_tabwidget_tabbar"));

Answer 2

What do you want to do to the tab bar?

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

Answer 3

As you mentioned, subclassing is the proper solution since it is protected. Something like this:

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

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

You can tell designer to "promote" your QTabWiget to a TabWidget then you will have an accessible tabBar() function.
