Another thing I've been struggling with is fetching data from a
TreeIter. Getting the iter itself is no problem, but when it comes to
getting the contents of a specific column within the iter, none of the
methods I've tried have worked. In fact, it almost seems like none of
them are implemented.
I've written a callback function named onChanged() in the MyComboBox
class that gets the TreeIter, but that's all I can get working. If
anyone knows how to grab data from column 2 of the iter (see the
MyListStore class at the bottom for the structure of the store) I'd be
ever so grateful if you could fill in whatever else would be needed in
that callback.
Here's the code:
```

The ListStore/TreeModel provides functions to retrieve the data,
`gtk.TreeModelIF.TreeModelIF.getValue`.
A TreeIter indicates the row these kind of function apply to.
