I’ve just started learning kivy and I am unable to get a black window when I run this code, and this is an error:
Kivy files require #:kivy !ex
This is my code snippet:
gui_python.py
from kivy.app import App from kivy.uix.label import Label from kivy.uix.gridlayout import GridLayout from kivy.uix.textinput import TextInput from kivy.uix.button import Button from kivy.uix.widget import Widget from kivy.properties import ObjectProperty class MyGridLayout(Widget): name = ObjectProperty(None) userId = ObjectProperty(None) def press(self): name = self.name.text userId = self.id.text # print(f'hello {name} , your id {id}') # self.add_widget(Label(text = f'name : {name} , id : {id}')) self.name.text = "" self.id.text = "" class MyApp(App): def build(self): return MyGridLayout() if __name__ == '__main__' : MyApp().run()
My my.kv file is:
<MyGridLayout> name:name userId:userId GridLayout: cols:1 size: root.width , root.height GridLayout: cols:2 Label: text: "user Name" TextInput: id :Name multiline:False Label: text: "user id" TextInput: id:userId multiline:False Button: text: "Submit" font_size: 32 on_press: root.press()

Answer
I use Builder.load_string() and paste my .kv code in it and that’s work
