tkinterで日付ピッカーを作成するにはどうすればよいですか？

Question

tkinterアプリでユーザーが日付を選択できる標準的な方法はありますか？

Answer 1

いいえ、Tkには日付ピッカーウィジェットは含まれていません。そこには試みることができるPythonのカレンダーウィジェットのカップルは、次のとおりです。No

http://svn.python.org/projects/sandbox/trunk/ttk-gsoc/samples/ttkcalendar.py

http://effbot.org/zone/wcklib-calendar.htm

Answer 2

ができますが、フォーマットされた文字列からdatetime型要素として、ユーザーからそれを得ることができます。..

例：

import datetime 

userdatestring = '2013-05-10' 
thedate = datetime.datetime.strptime(userdatestring, '%Y-%m-%d') 

チェックアウトhttp://docs.python.org/2/library/datetime.html#strftime-strptime-behaviorそれは便利ですが、日付を取得する最もユーザーフレンドリーな方法ではありません。

Answer 3

私の知る限りではありません。将来的にこれを実行したい人のために：

私はCalendarDialogを作るために（this SOポストからと修正）tkSimpleDialogとttkcalendar.pyを使用しました。 3つのファイルは私のgithubにあります。以下は

私CalendarDialog.pyのコードです：

import Tkinter 
import ttkcalendar 

import tkSimpleDialog 

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(): 
     cd = CalendarDialog(root) 
     print cd.result 

    button = Tkinter.Button(root, text="Click me to see a calendar!", command=onclick) 
    button.pack() 
    root.update() 

    root.mainloop() 


if __name__ == "__main__": 
    main()

これは、我々はTkinterではPythonの日付ピッカーをコーディングする方法です。
