Gtk.TextBuffer::apply-tag
function callback(text_buffer, tag:Gtk.TextTag, start:Gtk.TextIter, end:Gtk.TextIter, ):void;
The ::apply-tag signal is emitted to apply a tag to a range of text in a Gtk.TextBuffer. Applying actually occurs in the default handler.
Note that if your handler runs before the default handler it must not invalidate the start and end iters (or has to revalidate them).
