[pygtk] Having problems using gtk.CellRendererCombo

[John Wood]

Hello,

I'm having a hard time using a gtk.CellRendererCombo in my treeview
widget. The problem is that the combobox widget won't show. I've read
the pygtk reference a number times and the I get no errors executing
my code. I've created a small sample program which illustrates my
problem.

Any help is much appreciated, if someone can point me to a pygtk
program that uses gtk.CellRendererCombo that would be great.
