Please respond to the list.
The combobox only shows up when you click on the cell to edit it. If you
are expecting to see an arrow icon in each cell that is a combo box you
won't, I think that would get pretty messy and am glad it is not there.

Thank you for your response.
I got the code working almost the way I wanted. The only thing is that
I the actual widget is not visible. Is this the expected behavior? I
was under the impression that I would have a gtk.ComboBox in each of
the cells in the TreeViewColumn.
I include the current version of the sample program to show the "quirk".

The CellRendererCombo needs to be editable. The drop-down will only
appear when you click on the cell.
cellcombo.set_property("editable", True)
