i'm using the array-based model which we discussed before.  There is
one pointer for each row.  i use gtk_tree_view_insert_column_with_data_func
for each column, doing various transformations on the data to present
it to the user.

In this particular case, i have one column which is dependent on
global state QZ and one column which does not depend on QZ.  So when
QZ changes, i know only one column need to be redrawn

It's not a big deal, but you should know all the use-cases.
