Python 中的 Tkinter 菜单问题

Question

我实际上正在使用 Tkinter 在 Python 中开发图像编辑器（我知道 Python 不是最适合图像编辑的，但那是为了学校，我没有选择），我想做的是将每个打开的文件保存在另一个文件中添加到“文件”菜单中最后五个的快捷方式。 问题是，一开始没有问题，但是当我打开新图像时，它无法重新配置旧的快捷方式。 该错误似乎表明它尝试配置分隔符而不是命令。在使用了一些 print() 之后，Tkinter 似乎看到了前五个条目，然后跳转到了接下来的三个条目，然后看到了所有其他条目。 这有点搞乱了我的头。

这是代码：

    f=open('.recentlyUsed', 'r+')
    f.readline() #Skipping the empty first line.
    recents=f.read().split('\n')
    c=0
    recents2=[] 
    for i in recents:    #Deleting the doubles.
        if i not in recents2:
            recents2+=[i]
    recents=recents2[:]
    c=0
    while fichier.index(c)==c: #Getting the number of files already displayed in
        c+=1                        #the menu.
        print(fichier.entryconfigure(c)) #Test : Printing the entry to know which 
    c-=7                                      #Tkinter sees or not.
    if c>=0:
        fichier.insert_separator(5)      #Doesn't insert a separator if there's no file displayed.
    if len(recents)>=1:  #If there's already a file displayed, juste modifying the label (the command doesn't need to.)
        if c>=1:
            fichier.entryconfigure(7, label=srecents[-1])
        else:
            fichier.insert_command(6, command=lambda: openRecent(-1), label=recents[-1])
        if len(recents)>=2:
            if c>=2:
                fichier.entryconfig(8, label=recents[-2])
            else:
                fichier.insert_command(6, command=lambda: openRecent(-2), label=recents[-2])
            if len(recents)>=3:
                if c>=3:
                    fichier.entryconfig(9, label=.recents[-3])
                else:
                    fichier.insert_command(6, command=lambda: openRecent(-3), label=recents[-3])
                if len(recents)>=4:
                    if c>=4:
                        fichier.entryconfig(10, label=recents[-4])
                    else:
                        fichier.insert_command(6, command=lambda: openRecent(-4), label=recents[-4])
                    if len(recents)>=5:
                        if c>=5:
                            fichier.entryconfig(11, label=recents[-5])
                        else:
                            fichier.insert_command(6, command=lambda: openRecent(-5), label=recents[-5])
    f.close()

此代码返回以下内容：

那么如果有人可以看到问题来自哪里......？

Answer 1

最简单的解决方案是从头开始重新创建整个菜单，而不是尝试更新某些项目。它快速、简单，而且几乎万无一失。

如果您决定将最近的项目设为菜单上的最后一个项目，则可以仅删除最近的文件并附加一组新文件。这很容易，因为您知道最近文件开始的索引，除非您有一个因其他原因而增大和缩小的菜单。

因此，不要尝试就地更新项目，只需删除并重新创建即可。

Answer 2

那一长串 if 绝对是错误的做法。
我建议您首先删除所有旧的最近条目，然后添加新条目。
