問題描述

我正在嘗試制作一個小型俄羅斯方塊游戲，用于使用 kivy 學習 python.我正在嘗試創建一個大小為 20,20 的自定義小部件.當我將它添加到浮動布局并運行以下代碼時，我收到以下錯誤:

I am trying to make a small tetris game for learning python with kivy. I am trying to create a custom widget with size 20,20. When I add it to the float layout and run the below code I receive the following error:

錯誤:

File "D:OS FilesworkspaceTetrisholder.py", line 10, in __init__ self.add_widget(c)
File "C:Kivy180kivykivyuixfloatlayout.py", line 115, in add_widget pos_hint=self._trigger_layout)
TypeError: descriptor 'bind' of 'kivy._event.EventDispatcher' object needs an argument

代碼:holder.py 文件:

Code: holder.py File:

from items import Cell

class Holder(FloatLayout):
    def __init__(self, **kwargs):
        super(Holder,self).__init__(**kwargs)
        self.size=(300,300)
        c=Cell
        #c.pos= (20,20)
        self.add_widget(c)
        #self.add_widget(c)

items.py 文件:

items.py File:

from kivy.uix.widget import Widget
from kivy.graphics import *

class Cell(Widget):
    def __init__(self, **kwargs):
        super(Cell,self).__init__(**kwargs)
        with self.canvas:
            Color(1, 0, 0)
            Rectangle(pos=(0, 0), size=(50, 50))

        self.height=50
        self.width=50

main.py 文件:

main.py File:

from kivy.app import App
from holder import Holder

class start(App):
    def build(self):
        return Holder()

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

您能否解釋一下我哪里出錯了，我被困在起點本身.關于錯誤，我也沒有寫任何事件，它只是一個小部件類.能否請您解釋一下我在理解 kivy 方面出了什么問題.

Could you please explain where I went wrong, I am stuck at the starting point itself. Regarding the error, I haven't written any events also, and it is just a widget class. Could you please explain where I went wrong in understanding kivy.

推薦答案

c=Cell

我打賭你希望 c 成為 Cell 類的一個實例.如果你想這樣做，你需要這樣做:

I bet you want c to be an instance of the Cell class. If you want to do that, you need to do:

c=Cell()
