Such a thing can be easily achieved by creating a proxy model that sets 
the appropriate flag to make an item checkable and outputs the right 
checkstate from data() and sets it from setData(). I have just created 
one a week or two ago (sorry, can not share) which was quite simple. I 
abused a QItemSelectionModel inside my QSortFilterProxyModel subclass to 
keep track of what items were checked, which works well and results in 
remarkably little code. I use it on a QFileSystemModel and that works 
just fine.
