title: Change state attributes to a group of widgets in Tkinter
body: <p>I have a checkbutton which is associated to a group of other widgets. What I would like to do is when the checkbutton is checked I want to change all the the associated/child widgets state from disabled to active. </p>
  
  <p>I was thinking to change the state of my associated widgets from a callback function but I don't want to configure each widget individually.  Is there a way to group all the child widgets together so I can change all child widgets state all at once instead of configuring individually?</p>
  
  <pre><code>checkbutton 1 (unchecked)
      entry1 (disable)
      entry2 (disable)
      ...
      entry20 (disable)
  
  checkbutton is checked
  
  checkbutton 1 (checked)
      entry1 (active)
      entry2 (active)
      ...
      entry20 (active 
  </code></pre>
  
  <p>I am sure there has to be a way to group them so I don't have to configure each 20 widgets properties individually. this will be helpful so I can create dictionaries of my settings and then I can change large amount of widgets by changing my dictionary. </p>
