I think your problem steams from the line
dialog._model =3D gtk.ListStore(object)
Which I think should be more like
dialog._model =3D gtk.ListStore(str,str,str)
However this does not give you the dynamic nature you desire.
I don't know the limits of column expansion/contraction you require for =
your problem, .. but I see in your code you want to limit it to 20
(are they always strings?, or all columns the same type?)
I would create a listStore with 20 str as arguments.
I would then create the treeview with as many columns needed for the =
problem at hand
Attached you will see a modified prog that works for me, I limited the =
columns to 7, each time you press the dialog button, a list is =
dynamically generated with a random number of columns.
the list is always strings.
length of list correlates to number of colomns to view.
Don't know if this has been helpful?
