body: <p>I am trying create a GUI by implementing the template of the <a href="https://www.packtpub.com/packtlib/book/Application-Development/9781785286926/1/ch01lvl1sec13/Our%20project%20%20Comic%20Creator" rel="nofollow noreferrer">ComicCreator GUI</a> sample as a template for my own project. The <a href="https://www.packtpub.com/packtlib/book/Application-Development/9781785286926/1/ch01lvl1sec13/Our%20project%20%20Comic%20Creator" rel="nofollow noreferrer">code</a> is easy to follow, but I would like to  be able to reconfigure the <code>drawingspace.kv</code>, each time a button is pushed, say for example something like this:</p>
  
  <p><a href="https://i.stack.imgur.com/Wyzok.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Wyzok.png" alt="enter image description here"></a></p>
  
  <p><strong>Q:</strong> How could I configure the <code>drawingspace.kv</code> to have a different layout with different widgets for each button that is pressed?</p>
