Python Tkinter错误对象没有属性 [英] Python Tkinter error object has no attribute
问题描述
所以我正在制作类似于街机游戏的程序.我希望在单击框架后将lableGuess出现在顶层窗口中,但这会给我这个错误:
So I am making a program similar to the arcade games. I want the lableGuess to appear in the toplevel window after clicking the frame but it gives me this error:
AttributeError:窗口"对象没有属性窗口"
AttributeError: 'Window' object has no attribute 'window'
这是代码:
from tkinter import *
from tkinter import font
import time
class Window(Frame):
def __init__(self, master):
Frame.__init__(self, master)
self.master = master
master.title("Arcade Games")
master.geometry("800x600+560+240")
b = Button(self, text="Guess the number", command=self.new_window)
b.pack(side="top")
self.customFont = font.Font(master, font="Heraldica", size=12)
self.guess_number()
def new_window(self):
id = "Welcome to the 'Guess your number' game!\nAll you need to do is follow the steps\nand I will guess your number!\n\nClick anywhere to start!"
self.window = Toplevel(self.master)
frame = Frame(self.window)
frame.bind("<Button-1>", self.guess_number)
frame.pack()
self.window.title("Guess the number")
self.window.geometry("400x300+710+390")
label = Label(self.window, text=id, font=self.customFont)
label.pack(side="top", fill="both", padx=20, pady=20)
def guess_number(self):
labelGuess = Label(self.window, text="Pick a number between 1 and 10", font=self.customFont)
time.sleep(2)
labelGuess.pack(fill=BOTH, padx=20, pady=20)
if __name__ == "__main__":
root = Tk()
view = Window(root)
view.pack(side="top", fill="both", expand=True)
root.mainloop()
推荐答案
在您按下按钮并触发new_window
事件回调之前,可能已调用了初始化方法中对guess_number
的初始调用.在guess_number
中,您尝试将self.window
作为参数传递给Label()
,但那时它是未定义的.
Your initial call to guess_number
in your initializer method is probably being invoked before you press the button and trigger the new_window
event callback. In guess_number
you're trying to pass self.window
as an argument to Label()
but it would be undefined at that time.
