I think this will walk through all of the QListViewItems in a QListView
(haven't tried it though) and give you a list of selected items:

def getSelectedItems (listView):
    selectedLVIList = []
    listViewItem = listView.firstChild()

    scan(listViewItem, selectedLVIList)

    return selectedLVIList
        
def scan(listViewItem, selectedLVIList):    
    while listViewItem:
        if listViewItem.isSelected():
            selectedLVIList.append(listViewItem)

        scan(listViewItem.firstChild())

        listViewItem = listViewItem.nextSibling()

The docs say that you might not traverse the list view items in sort order
using firstChild/nextSibling. This also doesn't keep track explicitly of
which level an item is on, although you can trace back each item's
parent(s) (or else modify the code to track that).
