you can try to use

void QWidget::focusOutEvent ( QFocusEvent * event )

void QWidget::focusOutEvent ( QFocusEvent * event )

To copy to clipboard, switch view to plain text mode 

with

bool QWidget::focusNextPrevChild ( bool next )

bool QWidget::focusNextPrevChild ( bool next )

To copy to clipboard, switch view to plain text mode

I think you need to handle event from QTabBar, so next example is how to do this

TabWidget::TabWidget(QWidget *parent)
	: QTabWidget(parent)
{
	tabBar()->installEventFilter(this);
}
 
TabWidget::~TabWidget()
{
}
 
bool TabWidget::eventFilter(QObject *o, QEvent *event)
{
	if (event->type() == QEvent::KeyPress && o == tabBar()) {
		QKeyEvent *keyEvent = static_cast<QKeyEvent *>(event);
		if (keyEvent->key() == Qt::Key_Right) {
			if (currentIndex() != 2) {
				setCurrentIndex(2);
				QWidget *widget = this->widget(currentIndex());
				if (widget)
					widget->setFocus();
				return true;
			}
		}
	}
	return QTabWidget::eventFilter(o, event);
}

TabWidget::TabWidget(QWidget *parent)
	: QTabWidget(parent)
{
	tabBar()->installEventFilter(this);
}

TabWidget::~TabWidget()
{
}

bool TabWidget::eventFilter(QObject *o, QEvent *event)
{
	if (event->type() == QEvent::KeyPress && o == tabBar()) {
		QKeyEvent *keyEvent = static_cast<QKeyEvent *>(event);
		if (keyEvent->key() == Qt::Key_Right) {
			if (currentIndex() != 2) {
				setCurrentIndex(2);
				QWidget *widget = this->widget(currentIndex());
				if (widget)
					widget->setFocus();
				return true;
			}
		}
	}
	return QTabWidget::eventFilter(o, event);
}

I hope it helps you.
