Python Kivy On Screen Keyboard Focusing on Field

To make a Kivy on-screen keyboard focus on a specific text input field, you can use the focus property of the TextInput widget. Here's an example of how you can achieve this:

pythonCopy code
from kivy.app import App

from kivy.uix.boxlayout import BoxLayout

from kivy.uix.textinput import TextInput





class MyBoxLayout(BoxLayout):

    def __init__(self, **kwargs):

        super(MyBoxLayout, self).__init__(**kwargs)

        

        # Create a TextInput field

        self.text_input = TextInput()

        self.add_widget(self.text_input)

        

        # Set the on-screen keyboard to focus on the TextInput field

        self.text_input.bind(focus=self.on_textinput_focus)



    def on_textinput_focus(self, instance, value):

        # Check if the TextInput field has gained focus

        if value:

            # Open the on-screen keyboard

            self.text_input.keyboard_mode = 'system'

        else:

            # Close the on-screen keyboard

            self.text_input.keyboard_mode = 'managed'





class MyApp(App):

    def build(self):

        return MyBoxLayout()





if __name__ == '__main__':

    MyApp().run()

In this example, we create a TextInput field and add it to a BoxLayout. We bind the focus property of the TextInput to a callback function (on_textinput_focus) that will be triggered whenever the focus changes. When the TextInput gains focus, we set the keyboard_mode property to 'system', which will open the on-screen keyboard. When the TextInput loses focus, we set the keyboard_mode property to 'managed', which will close the on-screen keyboard.

You can run this code to see the on-screen keyboard automatically open when you tap on the TextInput field and close when you tap outside the field. Adjust the layout and styling as needed to fit your application's design.
