Python中的Tkinter菜单的问题

Question

我实际上正在与Tkinter一起编写Python中的图像编辑器（我知道Python不是图像编辑的最佳选择，但这是为了学校，我没有选择）以及我在尝试要做的是将每个打开的文件保存在另一个文件中，以便在文件菜单中为最后五个文件添加快捷方式。 问题是，在开始时没有问题，但是当我打开新图像时，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。在玩过一些print（）之后，似乎Tkinter看到前五个条目，然后跳转下三个，然后看到所有其他条目。 这是有点messin'我的头。

下面的代码：

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() 

而这种代码返回如下：

所以，如果有任何人谁可以看到哪来的问题来自...？

Answer 1

这条长长的if的链肯定是这样做的错误方式。 我建议你先删除所有旧的最近条目，然后添加新的条目。

Answer 2

最简单的解决方案是从零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，几乎万无一失。

如果您决定将最近的项目作为菜单上的最后一项，您只能删除最近的文件并添加一个新的设置。这很容易，因为你知道最近文件开始的索引（除非你有一个菜单因其他原因而增长和缩小，这将是一个全能的坏主意）。

因此，不要试图更新项目，只是删除并重新创建。
