title: Tkinter Listbox with Entry
body: <p>Is there a way to have the items of a Tkinter Listbox be Entry Widgets? The result would be that you could dynamically modify the text in an Listbox entry. If your Listbox looks like:</p>
  
  <pre><code> --------
  | Apples  |
  | Pears   |
  | Oranges |
   ---------
  </code></pre>
  
  <p>then you would want to be able to click on Apples and write some arbitrary text - you could then bind the Enter key, say, to trigger a function based on the new text.</p>
