I am trying to capture when an user presses Ctrl+Enter on his keyboard while being in my application:



class UI(Widget):
def __init__(self, **kwargs):
super(UI, self).__init__(**kwargs)
self._keyboard = Window.request_keyboard(self._keyboard_closed, self)
self._keyboard.bind(on_key_down=self._on_keyboard_down)

def _keyboard_closed(self):
self._keyboard.unbind(on_key_down=self._on_keyboard_down)
self._keyboard = None

def _on_keyboard_down(self, keyboard, keycode, text, modifiers):
if keycode[1] == 'w':
print("yes")
return False
return True


class UIApp(App):
def build(self):
return UI()

UIApp().run()


I realize that this code would capture w, but it doesn't even do this. Or at least yes isn't printed to console. My UI:



#:kivy 1.0.9

<UI>:
title: 'InputDialog'
auto_dismiss: False

RelativeLayout:
...

          Check modifiers[0] == 'ctrl' and keycode[0] == 13 or text is None:
