Is there a preferred way to detect when all of a QTreeWidgetItem's children are marked as hidden? Currently, I'm iterating over all of them every time any of them are hidden.

Keep a counter of hidden items and change the value of the counter if an item changed its state of hidden-ness. So each time you use the information you do not iterate over all items!

I don't know if this solved my problem, but it sounds reasonable! – moswald Nov 28 '17 at 22:54
