Tkinter | Adding style to entered text using the ttk.Entry widget

Michael Zippo

Login Widgets are used to retrieve an entry from a user. It can be created like this:

 entry = ttk.Entry (master, option = value, ...)

Code # 1: Creating a widget Entry and getting user input (getting only String data).

# tkinter imports

from tkinter import *

from tkinter import ttk

from tkinter.messagebox import askyesno

# creating root

root = Tk ()

# specifying geometry

root.geometry ( ’200x100’ )

# This is used to get input from the user
# and show it in the Entry Widget.
# Whatever data we receive from the keyboard
# will be treated as a string.

input_text = StringVar ()

entry1 = ttk.Entry (root, textvariable = input_text, justify = CENTER)

   
  # focus_force used for focus  
  # as soon as the application starts  
  entry1.focus_force ()  
   entry1.pack (side   =   TOP, ipadx   =   30  , ipady   =   6  ) 
   
   save   =   ttk.Button (root, text   =   ’Save’  , command   =   lambda  : askyesno (
    ’ Confirm’  ,   ’Do you want to save? ’ )) 
   save.pack (side   =   TOP, pady   =   10  ) 
   
  root.mainloop ()

Output:

In the above output, once you run the code, the button, a confirmation message appears asking if you want to save the text or no (the text will not be saved, it is only used to display the button’s functionality).

Code # 2: add style to the entered text in the input widget.

       # tkinter import  
   from   tkinter   import   *  
   from   tkinter   import   ttk 
   from   tkinter.messagebox   import   askyesno  
    
  # create root  
   root   =   Tk () 
   root.geometry ( ’ 200x100’  ) 
   
   input_text   =   StringVar () 
   
  # This class is used to add style  
  # to any available widget  
   style   =   ttk.Style ( ) 
   style.configure (  ’TEntry’  , foreground   =   ’green’  )  
    
   entry1   =   ttk. Entry (root, textvariable   =   input_text, justify   =   CENTER, 
   font   =   (  ’courier’  ,   15  ,   ’bold’   )) 
   entry1.focus_force () 
   entry1.pack (side   =   TOP, ipadx   =   30  , ipady   =   10  ) 
    
   save   =   ttk. Button (root, text   =   ’Save’  , command   =   lambda  : askyesno (
   ’Confirm’  ,  ’ Do you want to save? ’ )) 
   save.pack (side   =   TOP, pady   =   10  ) 
   
  root.mainloop ()

Output:

In the above output, you may notice that the font color has changed, the font family has changed, the text is larger than normal, and the text is in bold. This is because we are adding styling to the text we enter.
