python之_tkinter.TclError : can't pack when trying to add ttkcalendar into tkinter GUI

我正在尝试将 ttk 日历 添加到我的 Tkinter GUI 中。问题是它引发了 _tkinter.TclError: can't pack .34164128 inside .34161248.34161448.34161608

import Tkinter 
import tkSimpleDialog 
 
import ttkcalendar 
 
 
class CalendarDialog(tkSimpleDialog.Dialog): 
    """Dialog box that displays a calendar and returns the selected date""" 
 
    def body(self, master): 
        self.calendar = ttkcalendar.Calendar(master) 
        self.calendar.pack() 
 
    def apply(self): 
        self.result = self.calendar.selection 
 
 
# Demo code: 
def main(): 
    root = Tkinter.Tk() 
    root.wm_title("CalendarDialog Demo") 
 
    def onclick(): 
        print 'click' 
 
    cd = CalendarDialog(root) 
    button = Tkinter.Button(root, text="Click me to see a calendar!", command=onclick) 
    button.pack() 
    root.update() 
 
    root.mainloop() 
 
 
if __name__ == "__main__": 
    main()

你知道问题出在哪里吗？

请您参考如下方法:

错误是您在 CalendarDialog 类中没有 __init__ 方法。所以只需将 body 方法重命名为 __init__ 即可。现在您已经在每次创建实例时都初始化了实例，并且定义了 pack() 方法。
