[pygtk] Looking for help with comboboxes

[Gerald Britton]

Hi -- I'm trying to learn how to use comboboxes.  I worked up a little
program to try to test it out (below, with imbedded glade).  I tried
two methods to get stuff to show in the box, but to no avail.  In the
first method I used the append_text method on the combobox.  In the
second method I used the append method on the liststore.  Obviously
I'm missing something but this newbie can't see what.  I tried both
methods separately and together with the same (bad) result.

Would someone be able to point out what I am missing?

glade = """
<?xml version="1.0"?>
<interface>
  <requires lib="gtk+" version="2.16"/>
  <!-- interface-naming-policy project-wide -->
  <object class="GtkListStore" id="liststore">
    <columns>
      <!-- column-name gchararray1 -->
      <column type="gchararray"/>
    </columns>
  </object>
  <object class="GtkWindow" id="window">
    <property name="title" translatable="yes">Sample window with combo
box</property>
    <property name="default_width">440</property>
    <property name="default_height">250</property>
    <signal name="destroy" handler="on_window_destroy"/>
    <child>
      <object class="GtkComboBox" id="combobox">
        <property name="visible">True</property>
        <property name="model">liststore</property>
      </object>
    </child>
  </object>
</interface>
"""

import gtk
g = gtk.Builder()
g.add_from_string(glade)
g.connect_signals({ "on_window_destroy" : gtk.main_quit })

w = g.get_object('window')
c = g.get_object('combobox')
l = g.get_object('liststore')

for i in range(10):
  c.append_text("line %d" % i)  # 1. try to append the text to the combobox
  l.append(["line %d" % i])        # 2. try to add the text to the
liststore in the combobox.

w.show()
gtk.main()
