tkinter删除列表框中多个未选择的项目。

Question

我在用tkinter删除列表框中未选择的项目时遇到了一些麻烦,它有时可以工作......但主要是失败的,问题是当你选择了多个项目并点击 "Ocultar no seleccionats "按钮时,你必须删除所有未选择的项目。

解决办法是把所有的词用空格隔开，然后重建列表框的内容。

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

我使用这个功能来删除选中的项目。

def _del():
    n = 0
    for i in lb.curselection():
        lb.delete(i - n)
        n += 1

Button(f3, text='Del', relief=GROOVE, command=_del).pack(fill=X)

也可以用这个方法删除未选择的项目，

def _delUsl():
    file_lsObj.set([lb.get(i) for i in lb.curselection()])
