Python – English (Latin) to Hindi (Devanagiri) text convertor GUI using Tkinter

Prerequisites : Introduction to tkinter | Text transliteration from English to Indian languages – Using indic-transliteration

Python offers multiple options for developing a GUI (Graphical User Interface). Out of all the GUI methods, tkinter is the most commonly used method. It is a standard Python interface to the Tk GUI toolkit shipped with Python. Python with tkinter outputs the fastest and easiest way to create GUI applications. Now, it’s up to the imagination or necessity of a developer, what he/she wants to develop using this toolkit.

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.

Let’s create a GUI based English(Latin) to Hindi(Devanagari) text-convertor application that can convert text input given by user into Devanagari text.

Below is the implementation :

# import sanscript class from the indic_transliteration module
from indic_transliteration import sanscript
  
# import transliterate method from sanscript
# class of the indic_transliteration module
from indic_transliteration.sanscript import transliterate
  
# import all functions from the tkinter  
from tkinter import *
  
# 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 convert into Devanagari text 
def convert() :
  
    # get a whole input content from text box
    # ignoring \n from the text box content
    input_text = text1_field.get("1.0", "end")[:-1]
  
    # converted into the given devanagari
    # transliterated text
    output_text = transliterate(input_text, sanscript.ITRANS, 
                                            sanscript.DEVANAGARI)
    
    text2_field.insert('end -1 chars', output_text)
  
  
# Driver code 
if __name__ == "__main__"
  
    # Create a GUI window 
    root = Tk()
  
    # Set the background colour of GUI window  
    root.configure(background = 'light green')  
      
    # Set the configuration of GUI window (WidthxHeight) 
    root.geometry("400x350")  
  
    # set the name of tkinter GUI window  
    root.title("Converter")
      
    # Create Welcome to Latin to Devanagiri text converter
    headlabel = Label(root, text = 'Welcome to Latin to Devanagiri text converter',  
                      fg = 'black', bg = "red")  
    
    # Create a " Latin Text " label  
    label1 = Label(root, text = " Latin Text "
                 fg = 'black', bg = 'dark green'
        
    # Create a " Devnagiri Text " label  
    label2 = Label(root, text = " Devnagiri 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 .
    # pady keyword argument used to set paading along y-axis . 
    label1.grid(row = 1, column = 0, padx = 10, pady = 10)  
    label2.grid(row = 3, column = 0, padx = 10, pady = 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 Convert Button and attached  
    # with convert function  
    button1 = Button(root, text = "Convert into Devnagiri text"
                     bg = "red", fg = "black", command = convert) 
        
    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()
