python - “MultiColumnListbox”对象没有属性“curselection”

Question

我的 MultiColumnListbox 出现错误。我正在尝试了解如何解决此问题。我正在尝试查看在我的多列列表框中选择的内容。多列列表框是使用 tkinter 构建的，并且有一个提交按钮，该按钮应该运行一个函数，告诉我在多列列表框中选择了哪些行。我收到此错误“MultiColumnListbox”对象没有属性“curselection”并且似乎无法修复它。

这是我的代码

    window = tk.Tk()
    window.title("Multicolumn Treeview/Listbox")
    listbox = MultiColumnListbox()

    def submitFunction():
        print(listbox.curselection(self))
        window.destroy()

    def closeFunction():
        window.destroy()

    submit = tk.Button(window, text='Submit', command=submitFunction)
    submit.pack(side=tk.RIGHT, padx = 20)

    close = tk.Button(window, text='Close', command=closeFunction)
    close.pack(side=tk.RIGHT)

    window.mainloop()

这是我的问题的主要部分

        def submitFunction():
        print(listbox.curselection(self))
        window.destroy()

我最终将尝试获取索引号以删除给定的文件路径
