Kivy -黑屏问题

Question

为什么kivy中的以下代码会出现黑屏？MyGrid类未实例化。

from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.gridlayout import GridLayout
from kivy.uix.textinput import TextInput


class MyGrid(GridLayout):
    def __int__(self, **kwargs):
        super(MyGrid, self).__init__(**kwargs)
        self.cols = 2
        self.add_widget(Label(text="First name="))
        self.firstName = TextInput(multiline=False)
        self.add_widget(self.firstName)


class Myapp(App):
    def build(self):
        return MyGrid()


if __name__ == '__main__':
    Myapp().run()

Answer 1

您编写的是__int__而不是__init__
