Subject: Re: Ruby/Tk: how to get Scrollbar to stay scrolled on non-scroll 	widget?

Sorry for replying to myself, but I just stumbled on a possible
solution: using the typical
    @v_scroll.set(@first_viz,@last_viz)
at the end of the yview() declaration.  In my few trials it seems to
work even though it doesn't fit in the prescribed callback mechanism
that every book and website describes.  Which, incidentally, is why I
didn't think of it sooner.

Does this add a problem that will bite me later?
