How to append rows to Gtk.ListStore?

im trying to switch my application from python2.7 pyGTK to Python3 and pyGObject and having hard time with appending rows to my Gtk.ListStore :/

This code:

#!/usr/bin/env python3

from gi.repository import Gtk

listStore = Gtk.ListStore(str)
itr = Gtk.TreeIter()
listStore.append(itr)
listStore.set_value(itr, 0, 'Its working')

gives me always error:

Traceback (most recent call last):
  File "./test.py", line 7, in <module>
    listStore.append(itr)
  File "/usr/lib/python3/dist-packages/gi/overrides/Gtk.py", line 1017, in append
    return self._do_insert(-1, row)
  File "/usr/lib/python3/dist-packages/gi/overrides/Gtk.py", line 1008, in _do_insert
    row, columns = self._convert_row(row)
  File "/usr/lib/python3/dist-packages/gi/overrides/Gtk.py", line 850, in _convert_row
    if len(row) != n_columns:
TypeError: object of type 'TreeIter' has no len()

what is going on? How can I append new row into Gtk.ListStore?

Solution

  • Simply use the following command:

    itr = store.append(['Its working', ])

    You can find more example in The Python GTK+ 3 Tutorial.
