Kivy OS X - SDL2 提供程序 - 键盘修饰符不起作用

Question

我使用 Mac OS X 10.12 Sierra、Kivy 1.9.1、Python 2.7.3

修饰符不适用于以下代码：

#......
def __init__(self):
    self._keyboard = Window.request_keyboard(self._keyboard_closed, self)
    self._keyboard.bind(on_key_down=self.on_key_down_cb)

def on_key_down_cb(self, keyboard, keycode, text, modifiers):
    print(keycode)
    print(text)
    print(modifiers)

当我按“a”、“b”、“c”时，按住“shift”和“a”、“b”、“c”

我期待 abcABC （连接“文本”参数）

但输出是 abcİabc

--输出：

是否有影响键盘行为的配置？

解决方案：

改用 on_textinput

Keyboard.bind(on_textinput=cb)
