So the mapping doesn’t work and I end up displaying a contextual menu on the newly created “Tab 2”, even though the user right-clicked on the ‘+’ tab.   The behavior I want is right-clicking on the ‘+’ should do nothing; it shouldn’t add a new tab, it shouldn’t show a contextual menu.   What am I missing?  Or how should I be trying to do this?  If there was a separate signal for left vs. right clicks, it’d be easy.  But I don’t see a way to easily detect in slotTabBarClicked(int) that it was a right-click that caused currentChanged(int) to be emitted… How about avoiding currentChanged() and creating new tab in mousePressEvent() if its the left mouse button?
