  <pre><code>.................code..............................
  self.frame_verDatabase = Listbox(master, selectmode = EXTENDED)
          self.frame_verDatabase.bind("&lt;&lt;ListboxSelect&gt;&gt;", self.OnDouble)
          self.frame_verDatabase.insert(END, *Database.xoomDatabase) 
          self.frame_verDatabase.pack()
  
          self.frame_verDatabase.config(height = 70, width = 150)
  
      def OnDouble(self, event):
          widget = event.widget
          selection=widget.curselection()
          value = widget.get(selection[0])
          print ("selection:", selection, ": '%s'" % value)
  </code></pre>
  
  <p>Example:
  When I make a selection in the listbox, this data gets returned:</p>
  
  <pre><code>selection: (2,) : '{'Fecha de Entrega': '', 'Num Tel/Cel': 'test3', 'Nombre': 'test3', 'Num Orden': '3', 'Orden Creada:': ' Tuesday, June 23, 2015', 'Email': 'test3'}'
  </code></pre>
