Overview

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.
