No method found matching xxxx

I get the following printouts on my terminal when I start Ginga:

No method found matching 'gs_swipe'
No method found matching 'ms_draw'
No method found matching 'kp_poly_add'
No method found matching 'kp_edit_del'
No method found matching 'ms_cursor'
No method found matching 'ms_none'
No method found matching 'kp_poly_del'
No method found matching 'ms_wheel'
No method found matching 'gs_tap'

It is emitted by ImageViewBindings.setup_settings_events() method in Bindings.py, in the following logic block:

            # Register for this symbolic event if we have a handler for it
            try:
                cb_method = getattr(self, name)

            except AttributeError:
                self.logger.warning("No method found matching '%s'" % (name))
                cb_method = None

And then farther down the codes, I see one of the offending callback name is explicitly commented out:

    ## def ms_draw(self, viewer, event, data_x, data_y):
    ##     return False

So, I gather there are no methods defined for the callbacks in the message but they are done on purpose. And there is nothing a user can do about it, so why emit such a warning?

p.s. Does vacation mean you walk 10 feet down to the beautiful Hawaiian beach? No that’s just called “after work”

Yes. Thanks!
