Errror: _tkinter.TclError: bad window path name ".!button"
Errror: _tkinter.TclError: bad window path name ".!button"
所以今天我第一次尝试使用python 类,去除对global关键字的过度使用。我正在尝试创建一个 tkinter window,在其中,当我们单击一个按钮时,它会删除单击的按钮并将其替换为新按钮。当我们再次单击它时,它会删除此按钮并替换旧的(第一个)按钮,这应该会循环...
这是我编写的代码:
# ================= Importing Modules ===================
from tkinter import *
import tkinter as tk
# ====================================================
class Test():
# ============= Play Button Click =============
def fun1(self):
self.hi.destroy()
self.he.place(x=350,y=340)
# ============ Pause Button Click =============
def fun2(self):
self.he.destroy()
self.hi.place(x=350,y=340)
# ============ Player Window ================
def __init__(self):
self.root = Tk()
self.root.geometry('700x400')
self.root.resizable(0,0)
self.root["bg"] = "black"
self.hi = tk.Button(self.root, text="button 1", bg="white", bd=0, command=lambda: self.fun1() , relief=RIDGE)
self.hi.place(x=350,y=340)
self.he = tk.Button(self.root, text="button 2", bg="white", bd=0, command=lambda: self.fun2() , relief=RIDGE)
self.root.mainloop()
# ============== Calling ===========
if __name__ == '__main__':
Test()
但不幸的是,我得到的不是预期的输出:
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Program Files\Python310\lib\tkinter\__init__.py", line 1921, in __call__
return self.func(*args)
File "C:/XXX/XXX/Desktop/test.py", line 29, in <lambda>
self.he = tk.Button(self.root, text="button 2", bg="white", bd=0, command=lambda: self.fun2() , relief=RIDGE)
File "C:/XXX/XXX/Desktop/test.py", line 16, in fun2
self.hi.place(x=350,y=340)
File "C:\Program Files\Python310\lib\tkinter\__init__.py", line 2477, in place_configure
self.tk.call(
_tkinter.TclError: bad window path name ".!button"
所以我的问题是:
doubt1 = Any idea what I am doing wrong?
doubt2 = Or isn't this possible?
if doubt1 or doubt2:
Please explain it...
elif:
Please tell me a better alternative or idea, how to do this efficiently.
else:
Note: I have researched so many questions. Nothing helped me out. Especially ---|

您正在销毁 self.hi
,然后尝试在销毁的按钮上调用 place
。一旦小部件被销毁,您将无法再使用它。
如果您想继续循环按钮,请不要破坏它们。由于您使用的是 place
,因此您可以使用 self.hi.place_forget()
和 self.he.place_forget()
从视图中删除按钮而不破坏它们。
