每当我尝试在tkinter Toplevel中创建形状时，都会出现此错误消息：
Traceback (most recent call last):
File "C:\Users\tkinter\__init__.py", line 1705, in __call__
return self.func(*args)
File "C:/Users/filea.py", line 183, in nxt_lvl
paddle = Paddle(canvas, 'blue')
File "C:/Users/filea.py", line 125, in __init__
self.id = canvas.create_rectangle(0, 0, 100, 10, fill=color)
AttributeError: 'Toplevel' object has no attribute 'create_rectangle'

答案 0 :(得分：0)
考虑以下代码：
lvl2 = Toplevel(width=tkwidth + 100, height=tkheight + 100, bd=0, highlightthickness=0)
lvl2.title('Level 2')
paddle = Paddle(lvl2, 'blue')
ball = Ball(lvl2, 3, paddle, 'green')
请注意，您正在lvl2传递给Ball和Paddle的地方，他们希望帆布。您需要在Toplevel内创建画布，并将画布传递到Ball和Paddle。
它看起来应该像这样：
lvl2 = Toplevel(width=tkwidth + 100, height=tkheight + 100, bd=0, highlightthickness=0)
lvl2.title('Level 2')
canvas = Canvas(lvl2)
canvas.pack(fill="both", expand=True)
paddle = Paddle(canvas, 'blue')
ball = Ball(canvas, 3, paddle, 'green')
