How to unset all custom QStyledItemDelegates from QListView?

Question

I set a few custom delegates in my list. When I do a reset of the model QListView::reset(); gets called but the delegates are not reset. Is this a bug, if not how can I reset all delegates?

Iterating over all rows and set the delegates to nullptr would work but is not a proper solution.

How do you set a delegates? Can we see some code? `QListView::reset` - is not resetting a model. Delegates are not related you your model at all. Possible you are misunderstanding Qt MVC. — Dmitry Sazonov, Nov 06 '14 at 10:57
Do you really need different delegates for all rows? Solution: connect to a `modelAboutToBeReset` slot and perform cleaning of delegates there. — Dmitry Sazonov, Nov 06 '14 at 11:01

Qt internally maintains an map of the custom row delegates but does not give acces to it. I ended up maintaining a list myself and unset them all if I need to using

void QAbstractItemView::setItemDelegateForRow(int row, QAbstractItemDelegate * delegate)

with a nullptr as delegate;
