Python – SpongeBob Mocking Text Generator GUI using Tkinter
  • Last Updated : 18 Jan, 2021

Prerequisites : Introduction to tkinter | SpongeBob Mocking Text Generator 

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 SpongeBob Mocking Text Generator GUI 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 SpongeBob Mocking Text Generator application that can generate SpongeBob Text from the input given by the user.
 

Below is the implementation :

# import all functions from the tkinter 
from tkinter import *
 
# import the random library
import random
 
# Function to clear both the text areas
def clearAll() :
    # whole content of text area  is deleted
    text1_field.delete(1.0, END)
    text2_field.delete(1.0, END)
 
# Function to Generate SpongeBob Mocking Text
def generate() :
 
    # get a whole input content from text box
    # ignoring \n from the text box content
    input_text = text1_field.get("1.0", "end")[:-1]
     
    # variable declaration for the output text
    output_text = ""
       
    # check the cases for every individual character
    for char in input_text:
           
        # check if the character is an alphabet
        if char.isalpha():
               
            # convert to upper case
            if random.random() > 0.5:
                output_text += char.upper()
                   
            # convert to lower case
            else:
                output_text += char.lower()
           
        # if character is not and alphabet
        # add it as it is
        else:
            output_text += char
   
    text2_field.insert('end -1 chars', output_text)

    # Create a GUI window

    # Set the background colour of GUI window 
    root.configure(background = 'light green'
     
    # Set the configuration of GUI window (WidthxHeight)
    root.geometry("400x350"

    # Create a "Output Text " label 
    label2 = Label(root, text = "Output Text"
                   fg = 'black', bg = 'dark green'
     
   
    # grid method is used for placing 
    # the widgets at respective positions 
    # in table like structure .
    headlabel.grid(row = 0, column = 1)
     
    # padx keyword argument used to set paading along x-axis .
    label1.grid(row = 1, column = 0, padx = 10
    label2.grid(row = 3, column = 0, padx = 10)
 
       
    # Create a text area box 
    # for filling or typing the information. 
    text1_field = Text(root, height = 5, width = 25, font = "lucida 13")
    text2_field = Text(root, height = 5, width = 25, font = "lucida 13")
        
    # padx keyword argument used to set paading along x-axis .
    # pady keyword argument used to set paading along y-axis . 
    text1_field.grid(row = 1, column = 1, padx = 10, pady = 10
    text2_field.grid(row = 3, column = 1, padx = 10, pady = 10)
 
       
    # Create a Generate Button and attached 
    # with generate function 
    button1 = Button(root, text = "Generate", bg = "red", fg = "black",
                                command = generate)
       
    button1.grid(row = 2, column = 1)
   
    # Create a Clear Button and attached 
    # with clearAll function 
    button2 = Button(root, text = "Clear", bg = "red"
                     fg = "black", command = clearAll)
     
    button2.grid(row = 4, column = 1)
     
    # Start the GUI 
    root.mainloop()
