Prerequisites: Introduction to Tkinter
Python offers multiple options for developing a GUI (Graphical User Interface). Out of all the GUI methods, Tkinter is the most commonly used method. Python with Tkinter outputs the fastest and easiest way to create GUI applications. In this article, we will learn how to create a GUI Calendar application using Tkinter, with a step-by-step guide.
To create a Tkinter:
The GUI would look like below:
Let’s create a GUI-based Calendar application that can show the calendar with respect to the given year, given by the user.
Below is the implementation:
Python3
# import all methods and classes from the tkinter
from tkinter import *
# import calendar module
import calendar
# Function for showing the calendar of the given year
def showCal() :
# Create a GUI window
new_gui = Tk()
# Set the background colour of GUI window
new_gui.config(background = "white")
# set the name of tkinter GUI window
new_gui.title("CALENDAR")
# Set the configuration of GUI window
new_gui.geometry("550x600")
# get method returns current text as string
fetch_year = int(year_field.get())
# calendar method of calendar module return
# the calendar of the given year .
cal_content = calendar.calendar(fetch_year)
# Create a label for showing the content of the calendar
cal_year = Label(new_gui, text = cal_content, font = "Consolas 10 bold")
# grid method is used for placing
# the widgets at respective positions
# in table like structure.
cal_year.grid(row = 5, column = 1, padx = 20)
# start the GUI
new_gui.mainloop()
# Driver Code
if __name__ == "__main__" :
# Create a GUI window
gui = Tk()
# Set the background colour of GUI window
gui.config(background = "white")
# set the name of tkinter GUI window
gui.title("CALENDAR")
# Set the configuration of GUI window
gui.geometry("250x140")
# Create a CALENDAR : label with specified font and size
cal = Label(gui, text = "CALENDAR", bg = "dark gray",
font = ("times", 28, 'bold'))
# Create a Enter Year : label
year = Label(gui, text = "Enter Year", bg = "light green")
# Create a text entry box for filling or typing the information.
year_field = Entry(gui)
# Create a Show Calendar Button and attached to showCal function
Show = Button(gui, text = "Show Calendar", fg = "Black",
bg = "Red", command = showCal)
# Create a Exit Button and attached to exit function
Exit = Button(gui, text = "Exit", fg = "Black", bg = "Red", command = exit)
# grid method is used for placing
# the widgets at respective positions
# in table like structure.
cal.grid(row = 1, column = 1)
year.grid(row = 2, column = 1)
year_field.grid(row = 3, column = 1)
Show.grid(row = 4, column = 1)
Exit.grid(row = 6, column = 1)
# start the GUI
gui.mainloop()
Output :
