That is not exactly what I am after. The view() gives me access to
events that occur while I am interacting with the popup. However, when
the popup is open, any events that are generated from interacting with
any other widget are diverted to the QComboBoxPrivateContainer and
never arrive anywhere else. Is my understanding correct? I really need
to know if a mouse or touch event occurs in other parts of the
application while the QComboBox popup is visible.
