Extended the code with a ttk.notebook and a button. Seems to work. Text
is added only at the last opened tab, by the button, I think I
understand why but will look into that later.
When I add a tab through the button, no event is generated. When adding
through a double-click or ctrl-n it does. Where does this difference
come from?
