[pygtk] Copying a TreeStore not working

[Abhinav Lele]

Hi,
I am trying to copy a tree store object using python copy.copy() function
but its not copying it. What can be the problem ?
The code snippet is :

def incrUpdate(txUpdate,tv,mdlDup):
# mdl , mdlDup are treestore instances
    mdl =3D tv.get_model()
    # Check for tags
    tagpos =3D txUpdate.find(':')
    if tagpos !=3D -1 :
        print "Tags not implemented."
        return
    print  len(mdl) , len(mdlDup)
    mdl =3D copy.deepcopy(mdlDup)
    print type(mdl) , len(mdl)

............

OUTPUT :
25 25
/media/z/code/mpXT/listfn.py:292: GtkWarning:
gtk_tree_model_iter_n_children: assertion `GTK_IS_TREE_MODEL (tree_model)'
failed
  print type(mdl) , len(mdl)
<type 'gtk.TreeStore'> 0



Why is len(mdl) zero ? Is this the wrong way to copy ?
