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”，HOLD“shift”和“a”，“b”，“c”

我期待abcABC （连接“文本”参数）

但输出是abcİabc

是否存在影响键盘行为的配置？

Answer 1

解决方案：

使用on_textinput代替

Keyboard.bind(on_textinput=cb)

Kivy OS X - SDL2提供程序 - 键盘修饰符不起作用
