Window¶
Core class for creating the default Kivy window. Kivy supports only one window per application: please don’t try to create more than one.
- class kivy.core.window.Keyboard(**kwargs)[source]¶
Bases:
kivy.event.EventDispatcher
Keyboard interface that is returned by
WindowBase.request_keyboard()
. When you request a keyboard, you’ll get an instance of this class. Whatever the keyboard input is (system or virtual keyboard), you’ll receive events through this instance.- Events:
- on_key_down: keycode, text, modifiers
Fired when a new key is pressed down
- on_key_up: keycode
Fired when a key is released (up)
Here is an example of how to request a Keyboard in accordance with the current configuration:
import kivy kivy.require('1.0.8') from kivy.core.window import Window from kivy.uix.widget import Widget class MyKeyboardListener(Widget): def __init__(self, **kwargs): super(MyKeyboardListener, self).__init__(**kwargs) self._keyboard = Window.request_keyboard( self._keyboard_closed, self, 'text') if self._keyboard.widget: # If it exists, this widget is a VKeyboard object which you can use # to change the keyboard layout. pass self._keyboard.bind(on_key_down=self._on_keyboard_down) def _keyboard_closed(self): print('My keyboard have been closed!') self._keyboard.unbind(on_key_down=self._on_keyboard_down) self._keyboard = None def _on_keyboard_down(self, keyboard, keycode, text, modifiers): print('The key', keycode, 'have been pressed') print(' - text is %r' % text) print(' - modifiers are %r' % modifiers) # Keycode is composed of an integer + a string # If we hit escape, release the keyboard if keycode[1] == 'escape': keyboard.release() # Return True to accept the key. Otherwise, it will be used by # the system. return True if __name__ == '__main__': from kivy.base import runTouchApp runTouchApp(MyKeyboardListener())
- callback¶
Callback that will be called when the keyboard is released
- keycode_to_string(value)[source]¶
Convert a keycode number to a string according to the
Keyboard.keycodes
. If the value is not found in the keycodes, it will return ‘’.
- release()[source]¶
Call this method to release the current keyboard. This will ensure that the keyboard is no longer attached to your callback.
- string_to_keycode(value)[source]¶
Convert a string to a keycode number according to the
Keyboard.keycodes
. If the value is not found in the keycodes, it will return -1.
- target¶
Target that have requested the keyboard
- widget¶
VKeyboard widget, if allowed by the configuration
- window¶
Window which the keyboard is attached too
- class kivy.core.window.WindowBase(**kwargs)[source]¶

Fired when the
Window
is being rotated.- on_close:
Fired when the
Window
is closed.- on_request_close:
Fired when the event loop wants to close the window, or if the escape key is pressed and exit_on_escape is True. If a function bound to this event returns True, the window will not be closed. If the event is triggered because of the keyboard escape key, the keyword argument source is dispatched along with a value of keyboard to the bound functions.
