[pygtk] TreeView / ListStore question: tabbing through coulmns

[Seth Mahoney]

Just on a hunch, if you insert a print statement like so:

def on_edit_item(renderer, row, text, col):
  print(text)
  model[row][col] = unicode(text)

Does it print the expected (new) text, or the old text (or anything at
all)?
