Python | Vkeyboard (virtual keyboard) in kivy

Kivy, a popular Python framework for developing multitouch applications, provides a widget called VKeyboard for creating a virtual keyboard.

The VKeyboard widget can be integrated into Kivy applications and can be useful for touchscreen applications where a physical keyboard may not be present.

Here's a simple example to demonstrate how to use the VKeyboard in Kivy:

1. Setup

Make sure you have Kivy installed:

pip install kivy

2. Kivy Application with VKeyboard

from kivy.app import App from kivy.uix.boxlayout import BoxLayout from kivy.uix.textinput import TextInput from kivy.uix.vkeyboard import VKeyboard class KeyboardApp(App): def build(self): layout = BoxLayout(orientation='vertical', padding=10, spacing=10) # Create a TextInput widget self.text_input = TextInput(hint_text="Type here using the virtual keyboard below") layout.add_widget(self.text_input) # Create a Virtual Keyboard self.vkeyboard = VKeyboard() # Bind the virtual keyboard to the text input self.text_input.bind(focus=self.on_text_input_focus) layout.add_widget(self.vkeyboard) return layout def on_text_input_focus(self, instance, value): if value: # If the text input is focused, show the virtual keyboard self.vkeyboard.show() else: # If the text input is not focused, hide the virtual keyboard self.vkeyboard.hide() if __name__ == "__main__": KeyboardApp().run()

In this example:

  • We created a TextInput widget to allow users to enter text.
  • A VKeyboard (virtual keyboard) is then created and displayed below the TextInput.
  • We added a binding to the focus property of the TextInput to show or hide the virtual keyboard based on whether the TextInput has focus.

When you run this application, you'll see a text input box. When you tap/click on the text input, the virtual keyboard will be displayed, allowing you to type using the virtual keyboard. If you click outside of the text input, the keyboard will hide.
