Use gtk.TreeModelFilter as the model for your combo box, and do one of
the following as appropriate:

1. Add an extra boolean column to the underlying model, and set the
visible column of the filter accordingly. The value of this column
(true/false) will be used to determine which rows are to be displayed.

Or

2. Create a new function, the return value of which (true/false) will
decide whether or not to display a given row, and set this as the
visible func in the filter
