Following up, I think you have to add a boolean 'sensitive' column to the
gtk.ListStore model of the gkt.ComboBox. Then associate the 'sensitive'
column with the 'sensitive' property of the CellRenderText instance using
the 'add_attribute' method.

For example:

# assuming combo box model has a text value (col 0) and boo sensitive value
(col 1)
combo_box.add_attribute( cell, 'sensitive', 1 )

You can get more info about associating cell render attribute here:
