title: Drag and Drop in Tkinter?
body: <p>What is the correct/official/proper/recommended way of accomplishing drag/drop in tkinter? My documentation section 24.1.1 includes:</p>
  
  <blockquote>
    <p>Tkdnd Drag-and-drop support for Tkinter. This is experimental and
    should become deprecated when it is replaced with the Tk DND.</p>
  </blockquote>
  
  <p>but I can find no other <em>official</em> documentation. Does Tkinter have drag/drop support at all? Is this something version dependant? Is this something not yet included in tk(tcl) which will then filter through to tkinter?</p>
  
  <p>I should stress that I am talking about drag/drop between different applications and that I am currently using python 2 (although any solution which relies on python 3 would still be of interest).</p>
