Question

我正在尝试在Tkinter中执行简单的 GUI 。我有一个Listbox，我希望用户知道Listbox中的数据类型，所以我想为它设置一个标签（上面）。

问题在于，当我设置标签时，此Listbox会消失。

l = Label(multiple_choose_days_listbox, textvariable=label_day_listbox , anchor=NW, justify='center')
l.pack()

解决方案可能很明显，但我是Tkinter中的新手。

你有什么建议吗？

import tkSimpleDialog

import db

class CalendarDialog(tkSimpleDialog.Dialog):
    """Dialog box that displays a calendar and returns the selected date"""

    def __init__(self, master):
        self.calendar = ttkcalendar.Calendar(master)
        # self.calendar.pack()

        return res_dict

    button = Tkinter.Button(root, text="Generate", command=get_result_dict)
    button.pack()

    root.update()
    root.mainloop()


if __name__ == "__main__":
    main()

应该是

l = Tkinter.Label(root, text="Label")
