title: Resizing tkinter listbox to width of largest item, using .grid
body: <p>I have two listboxes that are side by side. They use the lstBox.grid() method to order them in the window. I then have a dropdown option that changes the items displayed in one of the listboxes. The ultimate aim here is to be able to "add" items from one box to the other, and remove ones from the other. My issue is that I don't know how to expand the list box width to be that of the largest item it contains. I have a method that is used for handling when the dropdown is changed, and determining its value to change the items as appropriate, but te listbox doesn't change width.</p>
  
  <p>I am aware that by using <code>lstBox.pack(fill=X,expand=YES)</code>, the listbox will resize, but i'm using the <code>.grid()</code> geometry.</p>
  
  <p>Any suggestions?</p>
