[PyKDE] QAbstractItemView Question

I actually went ahead and made the changes I needed to move the data 
into the model.  Instead of just
replacing the data entirely, I have a loop for updating and inserting, 
and one for deleting.  Updating
existing data works great, adding/removing is where I'm having issues.

My data is based off ElementTree.  The first thing I do is create a 
dictionary that maps each element, to
its parent, and its row:

<Element 'g' at 0xf6bfeae8>: (<Element 'payload' at 0xf6bfe8d8>, 0),
 <Element 'e' at 0xf6bfe938>: (<Element 'g' at 0xf6bfeae8>, 0),
<Element 'e' at 0xf6bfeb90>: (<Element 'g' at 0xf6bfeae8>, 1),
<Element 'e' at 0xf6bfeba8>: (<Element 'g' at 0xf6bfeae8>, 2),
<Element 'e' at 0xf6bfebc0>: (<Element 'g' at 0xf6bfeae8>, 3)

I can detect if one of these elements is not in the new ElementTree, 
but, how do I get the info needed
to call beginRemoveRows( QModelIndex parent, int row, int col).  I can 
get the row,col no problem,
but how can I get the deleted items parent QModelIndex?
