Kivy - How to access kivy widget in python?
<p>I want to edit a text in a TextInput in kivy but don't know how to, I've tried this code as Ive search in the net but still no luck.</p>

<pre><code>class MainApp(Screen):
    def __init__(self,**kwargs):
        super(MainApp,self).__init__(**kwargs)
    pass

class Forms(BoxLayout): 
    def __init__(self, **kwargs):
        super(Main,self).__init__(**kwargs)
        self.ids.txtSearch.text = "new text"

class Main(App):
    def build(self):
        return root_widget

if __name__ == "__main__":
    Main().run()

------kivy-------

&lt;Main&gt;:
    TextInput:
        id: txtSearch
</code></pre>

<p>this is not my whole code but I think those are what matters in the issue</p>

<p>this is the error:</p>
