The ::delete-range signal is emitted to delete a range from a gtk.TextBuffer

Note that if your handler runs before the default handler it must not invalidate the start and end iters (or has to revalidate them). The default signal handler revalidates the start and end iters to both point to the location where text was deleted. Handlers which run after the default handler (see g_signal_connect_after()) do not have access to the deleted text.
