title: How to get the value of a selected treeview item?
body: <p>I've looked at several posts regarding this and they've done the following</p>
  
  <p>-The output i get is blank</p>
  
  <p>-The output i get is the id, which is practically useless unless somebody can show me how to manipulate it</p>
  
  <p>-No output at all</p>
  
  <p>i just want to be able to click an item in treeview, and instantly be given the text i just clicked</p>
  
  <pre><code> def OnDoubleClick(event):
          item = course1_assessments.focus()
          print (item)
  
   course1_assessments.bind("&lt;&lt;TreeviewSelect&gt;&gt;", OnDoubleClick)
  </code></pre>
  
  <p>This code gives me 'I001' if i click the first item, and 'I002' when i click the second; id assume these are column values in the tree, but still useless to me</p>
