title: Initiating multiple widgets in Kivy
body: <p>Imagine this as the main.py:</p>
  
  <pre><code>class Widget1(Button):
      pass
  
  class Widget2(ButtonBehavior, Image):
      pass
  </code></pre>
  
  <p>And inside the .kv file:</p>
  
  <pre><code>&lt;Widget1&gt;:
      Button:
  
  &lt;Widget2&gt;:
      Image:
  </code></pre>
  
  <p>How do I initialize both <code>Widget1</code> and <code>Widget2</code> inside the main file? Creating separate <code>App</code>s doesn't work.</p>
