tkcalendar: Change output configuration for DateEntry()

Question

I am using the tkcalendar module that I just downloaded and would like to change the ~result~ background color and position if possible. The code I found on line is below;

try:
    import tkinter as tk
    from tkinter import ttk
except ImportError:
    import Tkinter as tk
    import ttk

from tkcalendar import Calendar, DateEntry

def example1():
    def print_sel():
        print(cal.selection_get())

    top = tk.Toplevel(root)

    cal = Calendar(top, font="Arial 14", selectmode='day', locale='en_US',
                   cursor="hand1", year=2018, month=2, day=5)

    cal.pack(fill="both", expand=True)
    ttk.Button(top, text="ok", command=print_sel).pack()


def example2():

    top = tk.Toplevel(root)

    cal = Calendar(top, selectmode='none')
    date = cal.datetime.today() + cal.timedelta(days=2)
    cal.calevent_create(date, 'Hello World', 'message')
    cal.calevent_create(date, 'Reminder 2', 'reminder')
    cal.calevent_create(date + cal.timedelta(days=-2), 'Reminder 1', 'reminder')
    cal.calevent_create(date + cal.timedelta(days=3), 'Message', 'message')

    cal.tag_config('reminder', background='red', foreground='yellow')

    cal.pack(fill="both", expand=True)
    ttk.Label(top, text="Hover over the events.").pack()


def example3():
    top = tk.Toplevel(root)

    ttk.Label(top, text='Choose date').pack(padx=10, pady=10)

    cal = DateEntry(top, width=12, background='darkblue',
                    foreground='white', borderwidth=2, year=2018)
    cal.pack(padx=10, pady=10)





root = tk.Tk()
ttk.Button(root, text='Calendar', command=example1).pack(padx=10, pady=10)
ttk.Button(root, text='Calendar with events', command=example2).pack(padx=10, pady=10)
ttk.Button(root, text='DateEntry', command=example3).pack(padx=10, pady=10)

root.mainloop()

This actually runs fine. I see the main root window below;

Now, when I select "DateEntry", once again everything is fine. I get the calendar pop up and I can select a date. But when I'm done selecting my date, I get the graphic below;

I would like to change the background color on the date and center the 8/29/18 in the center. I have not found any way to accomplish this. Any help would be appreciated.

DateEntry inherits from the ttk.Entry widget, so what you want can be done exactly the same way as with a ttk.Entry:

• The position of the text inside the entry is controlled by the justify option:

  dateentry.configure(justify='center')
  

• The color of the background can be changed via the fieldbackground option of a ttk style:

  style = ttk.Style(root)
  style.configure('my.DateEntry', fieldbackground='red')
  dateentry.configure(style='my.DateEntry')
