GUI Calendar using Tkinter

Creating a GUI calendar using tkinter is a great project to practice GUI programming in Python. You can utilize the calendar module along with tkinter to make this task simpler.

Here's a tutorial on how to create a basic calendar GUI using tkinter:

GUI Calendar using Tkinter Tutorial:

1. Import Required Libraries:

import tkinter as tk
from tkinter import ttk
import calendar

2. Create the Main Application Window:

root = tk.Tk()
root.title("GUI Calendar")

3. Function to Display Calendar:

We need a function that updates the text of a Text widget with the calendar of the selected month and year.

def display_calendar(year, month):
    cal_text = calendar.month(year, month)
    text_widget.delete(1.0, tk.END)
    text_widget.insert(tk.END, cal_text)

4. Dropdowns for Year and Month Selection:

We will use ttk.Combobox to create dropdown menus for selecting the year and the month.

# Current year and month to initialize the view
current_year = int(calendar.datetime.datetime.now().year)
current_month = int(calendar.datetime.datetime.now().month)

# Year dropdown
years = list(range(1900, 2101))  # Display years from 1900 to 2100
year_var = tk.IntVar(root)
year_var.set(current_year)
year_dropdown = ttk.Combobox(root, values=years, textvariable=year_var)
year_dropdown.pack(pady=10)

# Month dropdown
months = list(range(1, 13))
month_var = tk.IntVar(root)
month_var.set(current_month)
month_dropdown = ttk.Combobox(root, values=months, textvariable=month_var)
month_dropdown.pack(pady=10)

# Button to update calendar based on selection
def update_display():
    chosen_year = year_var.get()
    chosen_month = month_var.get()
    display_calendar(chosen_year, chosen_month)

update_btn = tk.Button(root, text="Display Calendar", command=update_display)
update_btn.pack(pady=20)

5. Text Widget to Display the Calendar:

text_widget = tk.Text(root, height=10, width=25, bg="light grey", fg="black")
text_widget.pack(padx=20, pady=20)

6. Initialize with Current Month's Calendar:

display_calendar(current_year, current_month)

7. Run the Main Loop:

root.mainloop()

Complete Code:

Combine all the snippets above to have a complete working GUI calendar using tkinter.

import tkinter as tk
from tkinter import ttk
import calendar

def display_calendar(year, month):
    cal_text = calendar.month(year, month)
    text_widget.delete(1.0, tk.END)
    text_widget.insert(tk.END, cal_text)

root = tk.Tk()
root.title("GUI Calendar")

current_year = int(calendar.datetime.datetime.now().year)
current_month = int(calendar.datetime.datetime.now().month)

years = list(range(1900, 2101))
year_var = tk.IntVar(root)
year_var.set(current_year)
year_dropdown = ttk.Combobox(root, values=years, textvariable=year_var)
year_dropdown.pack(pady=10)

months = list(range(1, 13))
month_var = tk.IntVar(root)
month_var.set(current_month)
month_dropdown = ttk.Combobox(root, values=months, textvariable=month_var)
month_dropdown.pack(pady=10)

def update_display():
    chosen_year = year_var.get()
    chosen_month = month_var.get()
    display_calendar(chosen_year, chosen_month)

update_btn = tk.Button(root, text="Display Calendar", command=update_display)
update_btn.pack(pady=20)

text_widget = tk.Text(root, height=10, width=25, bg="light grey", fg="black")
text_widget.pack(padx=20, pady=20)

display_calendar(current_year, current_month)

root.mainloop()

This code provides a basic GUI calendar where you can select a year and month from dropdown menus to display the respective calendar.

Python Tkinter calendar widget example: Tkinter provides a calendar module that includes a Calendar widget. Here's a simple example:

import tkinter as tk
from tkinter import ttk
from tkcalendar import Calendar

def on_date_selected():
    selected_date = cal.get_date()
    print(f"Selected Date: {selected_date}")

root = tk.Tk()
cal = Calendar(root, selectmode="day", year=2023, month=1, day=1)
cal.pack(pady=20)

button = ttk.Button(root, text="Get Selected Date", command=on_date_selected)
button.pack()

root.mainloop()

Creating a calendar app with Tkinter: Creating a calendar app involves using the Calendar widget and incorporating event handling for date selection.

import tkinter as tk
from tkinter import ttk
from tkcalendar import Calendar

def on_date_selected():
    selected_date = cal.get_date()
    print(f"Selected Date: {selected_date}")

root = tk.Tk()
cal = Calendar(root, selectmode="day", year=2023, month=1, day=1)
cal.pack(pady=20)

button = ttk.Button(root, text="Get Selected Date", command=on_date_selected)
button.pack()

root.mainloop()

How to display a calendar in Tkinter: Use the Calendar widget from the tkcalendar module to display a calendar in Tkinter.

import tkinter as tk
from tkcalendar import Calendar

root = tk.Tk()
cal = Calendar(root, selectmode="day", year=2023, month=1, day=1)
cal.pack(pady=20)

root.mainloop()

Tkinter calendar popup window: The calendar widget can be used in a popup window to allow users to select a date.

import tkinter as tk
from tkcalendar import Calendar

def open_calendar():
    top = tk.Toplevel(root)
    cal = Calendar(top, selectmode="day", year=2023, month=1, day=1)
    cal.pack(pady=20)

root = tk.Tk()
button = tk.Button(root, text="Open Calendar", command=open_calendar)
button.pack(pady=20)

root.mainloop()

Building a GUI Calendar in Tkinter: Building a GUI calendar involves creating a Tkinter application with the Calendar widget and additional components.

import tkinter as tk
from tkcalendar import Calendar

def on_date_selected():
    selected_date = cal.get_date()
    print(f"Selected Date: {selected_date}")

root = tk.Tk()
cal = Calendar(root, selectmode="day", year=2023, month=1, day=1)
cal.pack(pady=20)

button = tk.Button(root, text="Get Selected Date", command=on_date_selected)
button.pack()

root.mainloop()

Tkinter calendar widget customization: Customize the appearance and behavior of the Calendar widget using various options provided by the tkcalendar module.

import tkinter as tk
from tkcalendar import Calendar

root = tk.Tk()
cal = Calendar(root, selectmode="day", year=2023, month=1, day=1,
               background="darkblue", foreground="white", bordercolor="red")
cal.pack(pady=20)

root.mainloop()

GUI calendar with event handling in Tkinter: Enhance the GUI calendar by incorporating event handling for actions like date selection.

import tkinter as tk
from tkcalendar import Calendar

def on_date_selected():
    selected_date = cal.get_date()
    print(f"Selected Date: {selected_date}")

root = tk.Tk()
cal = Calendar(root, selectmode="day", year=2023, month=1, day=1)
cal.pack(pady=20)

button = tk.Button(root, text="Get Selected Date", command=on_date_selected)
button.pack()

root.mainloop()

Adding a calendar to Tkinter application: Integrate the Calendar widget into an existing Tkinter application to include a calendar feature.

import tkinter as tk
from tkcalendar import Calendar

def on_date_selected():
    selected_date = cal.get_date()
    print(f"Selected Date: {selected_date}")

root = tk.Tk()
cal = Calendar(root, selectmode="day", year=2023, month=1, day=1)
cal.pack(pady=20)

button = tk.Button(root, text="Get Selected Date", command=on_date_selected)
button.pack()

root.mainloop()
