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?
