The reason I have BaseView inheriting from QAbstractItemView is because
inside it I make calls like:
and so on. These are all things that are common to both
MyTreeView/MyTableView, and obviously wouldn't work if BaseView had no base
Any ideas of a better way to achieve this without duplicating code between
the 2 views?
