import widget in kivy file

Question

I created some custom widget.

from kivy.uix.widget import Widget
from kivy.lang import Builder


class ExampleWidget(Widget):
     Builder.load_file("kv/example.kv")

kv/example.kv

#:kivy 1.9.1

<ExampleWidget>:
    Label:
        text: Example

Than I want to create another widget with example widget. Like this:

kv/second.kv

#:kivy 1.9.1

<SecondWidget>:
    ExampleWidget:

But I got this error

kivy.factory.FactoryException: Unknown class <ExampleWidget>

Kivy can't find my custom widget, so how I can import it to another kivy file?

could you show a code example? – el3ien Jul 16 '16 at 21:53 — el3ien, Jul 16 '16 at 21:53

You can import it using following syntax (assuming that ExampleWidget is defined in example.py file and you have __init__.py in your directory):

#: import ExampleWidget example.ExampleWidget

<SecondWidget>:
    ExampleWidget:

Described in the documentation.

You dont even have to do that. The example he shows works fine for me. – el3ien Jul 16 '16 at 21:56
