title: Kivy ScrollView - Not Scrolling
body: <p>Looks like a common problem people have with Kivy. I've already checked other questions for the same problem here on SO but no luck.</p>
  
  <p>I have a container <strong>BoxLayout</strong>:</p>
  
  <pre><code>class Cnt(BoxLayout):
      pass
  </code></pre>
  
  <p>In the <strong>.kv</strong> file I've got something like this:</p>
  
  <pre><code>&lt;Cnt&gt;:
      orientation: 'vertical'
      ScrollView:
          size_hint: (1, .9)
          StackLayout:
              padding: 5
              size_hint_y: None
              id: content_layout
              minimum_height: self.height
              ARow:
              ARow:
              ARow:
              ARow:
              ARow:
              ARow:
              ARow:
              ARow:
              ARow:
              ARow:
              ARow:
              ARow:
              ARow:
              ARow:
              ARow:
      BoxLayout:
          size_hint: (1, .1)
          Label:
              text: 'A'
  </code></pre>
  
  <p><strong>ARow</strong> is a <strong>BoxLayout</strong> with a <strong>CheckBox</strong> and a <strong>Label</strong>. It has:</p>
  
  <pre><code>size_hint: (1, None)
  height: 40
  </code></pre>
  
  <p>As far as I understand these are the only two important things that could do something to the scrolling.</p>
  
  <p><strong>minimum_height: self.height</strong> is the same as if I would bind the minimum_height and height of the <strong>StackLayout</strong> in Python code if I understood it right.</p>
