You need to create a new model for this, and use TreeView::set_model().
If you are changing the number of columns then you probably do want to
change all the data anyway, so this makes sense.

I do this in glom, with the added complication that the model column
_types_ are determined at runtime too. It's not all that pleasant but it
works.

You mean you are adding TreeViewColumns that are not linked to any model
columns? I have never heard of that and I don't know if it should work.
You might ask on the GTK+ list about that kind of hackery. I'm not sure
what the point would be though.
