title: Accessing multiple kivy Classes from one single Class within Python side
body: <p>I have two Classes in python and 2 labels available within 2 different Classes in Kivy file which I would like to control from a single Python Class:</p>
  
  <pre><code>Class Python(BoyLayout):
      def __init__(self, **kwargs):
          super(Python, self).__init__(*kwargs)
          self.label1 = self.ids["label1"]
          self.label2 = self.ids["label2"]
  
     def changeText(self):
         self.label1.text = "New Text 1"
         self.label2.text = "New Text 2"
  
  Class NewClass(BoxLayout):
      pass
  </code></pre>
  
  <p>On kivy I have:</p>
  
  <pre><code>&lt;Python&gt;:
      BoxLayout: "vertical"
          Label:
              id:label1
              text: "Text 1"
  
  &lt;NewClass&gt;:
      BoxLayout: "vertical"
          Label:
              id:label2
              text: "Text 2"
  </code></pre>
  
  <p>In this example the change would only work for the change of label1 but of course it will not work for label2 as I need to access the NewClass property which is the part I am not able to workout. </p>
  
  <p>Also i would like to control all the kivy variables from the 1st Class ("Python" in this example) - hopefully this is possible</p>
  
  <p>Any cool help in order to understand?</p>
