Display a subset of the QAbstractItemModel

[youngw]

I've created a QAbstractItemModel and uses a tree view to show its contents. What I want to do next is to create another tree view to show a subset of the model. Should I make a copy of a portion of the original model (is there a quick way to do that)? or should the new tree view references the same model? if so, how would the new tree shows a subset of the model ?(say from a ModelIndex to another ModelIndex)

In the second view you should use an instance of QSortFilterProxyModel that will filter out the rows from the original model that you don't want.
