Python中的Tkinter菜單的問題

Question

我實際上正在與Tkinter一起編寫Python中的圖像編輯器（我知道Python不是圖像編輯的最佳選擇，但這是爲了學校，我沒有選擇）以及我在嘗試要做的是將每個打開的文件保存在另一個文件中，以便在文件菜單中爲最後五個文件添加快捷方式。 問題是，在開始時沒有問題，但是當我打開新圖像時，無法重新配置舊的快捷方式。 該錯誤似乎表明它嘗試配置分隔符而不是命令。在玩過一些print（）之後，似乎Tkinter看到前五個條目，然後跳轉下三個，然後看到所有其他條目。 這是有點messin'我的頭。

下面的代碼：

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() 

而這種代碼返回如下：

所以，如果有任何人誰可以看到哪來的問題來自...？

Answer 1

這條長長的if的鏈肯定是這樣做的錯誤方式。 我建議你先刪除所有舊的最近條目，然後添加新的條目。

Answer 2

最簡單的解決方案是從零開始重新創建整個菜單，而不是嘗試更新某些項目。它快速，簡單，幾乎萬無一失。

如果您決定將最近的項目作爲菜單上的最後一項，您只能刪除最近的文件並添加一個新的設置。這很容易，因爲你知道最近文件開始的索引（除非你有一個菜單因其他原因而增長和縮小，這將是一個全能的壞主意）。

因此，不要試圖更新項目，只是刪除並重新創建。
