最近,我尝试使用侧面板菜单创建一个完整的应用程序窗口,其中单独的框架运行一些功能并在画布框架中提交表单。
但我发现每次点击列表框中的任何条目时,它都会运行函数或方法,而不会清除现有的条目。
我试过destroy()而忘记()对我不起作用(也许我不确切知道如何使用它?!)和destroy()函数再次阻止使用该函数直到我关闭整个应用程序并再次运行它!)this is a photo of my problem
这是我的代码:
import tkinter as tk
from tkinter import ttk
class MainWindow() :
def __init__(self,root):
# menu left
self.menu_upper_frame = tk.Frame(root, bg="#dfdfdf")
self.menu_title_label = tk.Label(self.menu_upper_frame, text="menu title", bg="#dfdfdf")
self.menu_title_label.pack()

self.menu_left_upper = tk.Frame(self.menu_left_container, width=150, height=150, bg="red")
self.menu_left_upper.pack(side="top", fill="both", expand=True)
