无法在Tkinter中的Canvas上移动框架

问题描述

嘿，我有一个关于操作系统的学校项目，但是遇到了问题。我无法在桌面上打开窗口。 我使用框架创建了窗口，但是无法最小化，最大化并在Canvas上移动窗口。 我在下面共享我的代码：

from tkinter import *

import desktop_features.load_images as LoadImage
import os
lastx,lasty=None,None
default_window_size=(500,500)
default_window_coordinates=(150,150)
def move_window(e):

    
    desk.coords(window,e.x,e.y)

    
def on_l1(e):
    l1.config(fg='black',font=("Georgia",10,'underline'))
def off_l1(e):
    l1.config(fg='black',10))
def exit_requested(e):
    desk.delete(window)
    button.destroy()
    win.destroy()
    window_size="minimum"
def on_close_button(e):
    close_button.config(image=hover_close_window_button)
def off_close_button(e):
    close_button.config(image=close_window_button)

def on_min_max_button(e):
    min_max_button.config(image=hover_max_min_window_button)
def off_min_max_button(e):
    min_max_button.config(image=max_min_window_button)

    
window_size="minimum"
def resize_requested(e=None):
    global window_size,default_window_size
    if window_size=="minimum":
        win.config(height=s_height-53,width=s_width)
        desk.coords(window,s_width/2,s_height/2)
        win.pack(fill="both")
        
        window_size="maximum"
    elif window_size=="maximum":
        win.config(height=default_window_size[0],width=default_window_size[1])
        desk.coords(window,lastx,lasy)
        window_size="minimum"

        
def on_hide_button(e):
    hide_button.config(image=hover_hide_window_button)
def off_hide_button(e):
    hide_button.config(image=hide_window_button)
window_hide=True 
def hide_requested(e=None):
    global window_hide
    if window_hide==False:
        desk.itemconfigure(window,state='normal')
        window_hide=True
    elif window_hide==True:
        desk.itemconfigure(window,state='hidden')
