Tk Calendar widget problem

[bona25]

I am currently working on a tkinter calendar widget and gladly to find one in this site http://pythonical.sourceforge.net/dlgCalendar.py. It was truly a great help but there is something missing and i don't know how i can fix it. I am about to create said calendar on another window (except that of the main window) but upon clicking the choosen date on the widget, the result is nowhere to find...the date should be shown on Entry field (the one with "white" background on 'Date Picker' window...and i noticed that everytime i tried to create separate window for the result, the choosen date does not appear anymore...please help.

Below is my current formula:

from Tkinter import*
import tkMessageBox
import ttk
 
def dateDis():    
    app=Tk()
    app.title('Date Picker')
    app.geometry('400x300+300+400')
 
    import sys, string, calendar
    import Tkinter
    import time
    year = time.localtime()[0]
    month = time.localtime()[1]
    day =time.localtime()[2]
    strdate = (str(year) +  "/" + str(month) + "/" + str(day))
 
    tk = Tkinter
    fnta = ("Times", 10)
    fnt = ("Times", 12)
    fntc = ("Times", 12, 'bold')
 
    strtitle = "Calendar"
    strdays = "Mon  Tue  Wed  Thu  Fri  Sat Sun"
    dictmonths = {'1':'Jan','2':'Feb','3':'Mar','4':'Apr','5':'May','6':'Jun','7':'Jul','8':'Aug','9':'Sep','10':'Oct','11':'Nov','12':'Dec'}

For the StringVar to work, you have to tell Tkinter which top level window: date_var1 = StringVar(app)
I reorganized your code a little bit, and it seems to work:
