Answer: 
If you take a look at the [documentation for a QTreeWidgetItem](http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qtreewidgetitem.html), you will see there are a number of possible constructors for creating an instance. Though none of which it seems you are using in a way that is going to give you desirable results. The closest match to the signature you are providing is: 

`QTreeWidgetItem ( const QStringList & strings, int type = Type )` 

What this is probably doing is taking your string (I am assuming `row[0]` is a string because I don't know which drivers you are using) and applying it as a sequence, which would fullfill the requiremets of `QStringList`. Thus what you are getting is populating multiple columns of your item with each letter of your string value. If this is what you wanted, then you would n eed to tell your widget to show more columns: `self.treeWidget.setColumnCount(10)`. But this isn't what you are looking for I am sure.

More likely what you should be trying is to create a new item, then add the value to the desired column:

```
item = QTreeWidgetItem()
item.setText(0, unicode(row[0]))
self.treeWidget.insertTopLevelItem(0, item)

```

You can use the default constructor with no arguments, set the text value of the first column to your database record field value, and then add that item to the tree. You could also build up a list of the items and add them at once:

```
items = []
for row in c.fetchall():
    item = QTreeWidgetItem()
    item.setText(0, unicode(row[0]))
    items.append(item)
self.treeWidget.insertTopLevelItems(0, items)

```
Your first aproach could be corrected just add a list to the widgetitem not a string like this:

top\_node1 = QTreeWidgetItem([item\_value])
