For a single column text store I believe there is a convenience function
to tell the combo box which column to pull text from.
But what you are missing is cell renderers (one will be implicitly created
by setting the text column for the combo box, iirc).
As the combo box implements GtkCellLayout, you can use that interface
to add renderers (but you should be able to add renderers in Glade as well,
did you hit the "Edit.." button in the toolbar with the combo box selected ?).
