title: Scrolling multiple Tkinter listboxes together
body: <p>I have multiple Tkinter listboxes that I have scrolling together using a single scrollbar, but I'd ALSO like them to scroll together for mousewheel activity over any of the listboxes.  </p>
  
  <p>How to do this?</p>
  
  <p>My current code is based on the last pattern discussed here: <a href="http://effbot.org/tkinterbook/listbox.htm" rel="noreferrer">http://effbot.org/tkinterbook/listbox.htm</a>  It works fine when using only the scrollbar, but the listboxes scroll independently when the mousewheel is used.</p>
