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 :
- Importing the module – tkinter
- Create the main window (container)
- Add any number of widgets to the main window.
- Apply the event Trigger on the widgets.
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( "CALENDER" ) # 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 calender 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( "CALENDER" ) # 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() |
