Moving child widgets between QTabWidgets?

[Maurizio Berti]

If it throws that error, it's because the widgets (or their parent) have
been deleted.
Unfortunately, your code is insufficient to actually understand where the
issue is, and, by the way, it also has important issues: first of all the
second for loop is wrong (new_tab_widget is a widget, so that will throw an
exception), and using removeTab with the number of a counter is wrong, as
you'll always get even numbered items, if you want to remove all widgets,
always use removeTab(0).
I suggest you to provide a valid minimal reproducible example.
