its a completely analogous story. there is a handler for signal_event
for the regionview, and it will route into
PublicEditor::editor_canvas_.... () defined in editor_canvas_events.cc
which then switches on the event type and calls a specific event type
handler in Editor, passing in the relevant item type.

in this case, the connection is in region_view.cc:

	group->signal_event().connect (bind (mem_fun
(PublicEditor::instance(), &PublicEditor::canvas_region_view_event),
group, this));

and you can follow the chain from there
