tkinter刪除列表框中的多個未選定的項目

Question

我有一些麻煩，刪除與tkinter列表框的未選定的項目，它有時工作....但主要是失敗，問題是當您選擇多個項目，然後單擊在「Ocultar no seleccionats」按鈕上，您必須刪除所有未選中的項目。

解決方法是添加所有用最終空格分隔的單詞，然後重新構建列表框內容。

def ons(): 
    cs=StringVar 
    cs="" 
    a='' 
    for i in range(listbox.size()): 
     if listbox.select_includes(i): 
      cs +=listbox.get(i)+' ' #adding words ending with whitespace 
    listbox.delete(0,END) #deleting all the listbox content 
    for item in cs: 
     a=a+item 
     if item==' ': #full string passed 
      listbox.insert(END,a) #insert selected item into listbox 
      a=''#delete the string buffer
