I have a QTreeview and based on the users selection I would like to get a unique array containing all the names of the parents of the selected items.
So if any children are selected it would return the parent and if a parent is selected it would still return the parent.
Want returned:
>> [Kevin, Michelle, Nikki, Tim]
