カレンダーをtkinterのメニューに貼り付けてください。

Question

tkinterにはさまざまな条件があるメニューを作成しようとしています。そのうちの1つが日付の選択になります。これで、日付を手動で入力する必要があります。私はカレンダーを作りたい。私は、答えがto this questionであり、リンクがあるコードを使用すると考えました。しかし、私は自分のコードでそれを使う方法を知らない。

import numpy as np 
items5 = np.arange(1,14) 
items6 = np.arange(1, 28) 
items7 = np.arange(4, 28) 
choose_y_n = ['yes', 'no'] 
items12 = np.arange(50, 100) 
items13 = np.arange(0,15)

    def __init__(self, master, status, *options): 
     self.var = StringVar(master) 
     self.var.set(status) 
     OptionMenu.__init__(self, master, self.var, *options) 
     self.config(font=('Arial',(10)),bg='white',width=20) 
     self['menu'].config(font=('Arial',(10)),bg='white') 


root = Tk() 

optionList5 = items5 
optionList6 = items6 
optionList7 = items7 
optionList8 = choose_y_n 
optionList12 = items12 
optionList13 = items13 

lab = Label(root, text="Enter the date in the format 'dd.mm.yyyy'", font="Arial 10", anchor='w') 
ent1 = Entry(root,width=20,bd=3) 
lab5 = Label(root, text="condition №1", font="Arial 10", anchor='w')

labels = [lab, lab5, lab6, lab7, lab8, lab12, lab13] 
mymenus = [ent1, mymenu5, mymenu6, mymenu7, mymenu8, mymenu12, mymenu13]

    global values1 
    values1 = [ent1.get(), mymenu5.var.get(), mymenu6.var.get(), mymenu7.var.get(), mymenu8.var.get(), 
       mymenu12.var.get(), mymenu13.var.get()] 
    print(values1) 


def close_window(): 
    root.destroy() 

button = Button(root, text="Ok", command=save_selected_values) 
button1 = Button(root, text="Quit", command=close_window) 

for index, (lab, mymenu) in enumerate(zip(labels, mymenus)): 
    lab.grid(row=index, column=0) 
    mymenu.grid(row=index, column=1) 
    button.grid(row=index, column=2) 
    button1.grid(row=index, column=3) 

root.mainloop() 

私にとって、それは変数に日付を保存することが重要です：

は、以下の私のメニューのコードです。

私は非常にお勧めに感謝します！

UPD
新しいコードは以下のとおりです。

私のコードでは日付がまったく保存されないようです。

私は変数として日付を取得する方法を理解していません。私は間違って何をしていますか？

Answer 1

そのttkcalendar.pyは少しの助けが必要です。カレンダーウィジェットに新しい日付が選択されたときにアクションを実行し、イベントにバインドする必要がある場合。 _pressedメソッドの最後にあなたがと結合することができる仮想イベントを生成するために以下の行を追加しますので、しかし、それは現時点ではいずれも生成されていません。

self.event_generate("<<CalendarChanged>>") 

あなたは、あなたのUIにこのウィジェットを追加してバインドすることができ示すように、このCalendarChanged仮想イベントへの機能：ここで

def on_calendar_changed(event): 
    date = cal.selection 
    datestr = "{:%d.%m.%Y}".format(date) 
    print(datestr) 
    dateVar.set(datestr) 

cal.bind("<<CalendarChanged>>", on_calendar_changed) 

私はent1ウィジェットのtextvariableとしてdateVarという名前STRINGVARを設定します。カレンダーの選択が変更されると、正しくフォーマットされた文字列が入力ウィジェットに入れられます。

OptionMenuウィジェットからttk.Comboboxウィジェットに変換し、一般的に古いTkウィジェットよりもttkウィジェットを使用するとよいでしょう。
