QTabWidget Corner Widget Problem

[wysota]

That's not a good approach, you are not taking margins and spacing into consideration. It will fail if you click near a border of a tab. Use QWidget::mapTo() like this:

QPoint tabBarPoint = mapTo(tabBar()), event->pos());
int index = tabBar()->tabAt(tabBarPoint);

QPoint tabBarPoint = mapTo(tabBar()), event->pos());
int index = tabBar()->tabAt(tabBarPoint);
