The return of addItem, insertItem and other is always None<br>
<br>
...<br>
>>> cb = QtGui.QComboBox()<br>
>>> print cb.insertItem(0, "Item")<br>
None<br>
>>> print cb.addItem("Item")<br>
None<br>
>>><br>
<br>
Why are you using 'connect' ?<br>

<div>
for countries in cursor.execute("SELECT Country FROM

<div> self.ui.country_list.insertItems(0, countries)</div>
<br>
No ?<br>
