no time to test this, but iirc, the combobox content is held in an 
ordinary listbox widget, so you should be able to use the subwidget 
method to fetch that widget, and then use ordinary listbox methods to 
change the content.  Something like this:

     lb = w.subwidget("listbox")
     lb.delete(0, END) # delete all items
