Setting options for a Tkinter Widgets

When working with themed widgets, you often need to set their attributes e.g., text and image.

Tkinter allows you to set the options of a widget using one of the following ways:

  • At widget creation, using keyword arguments.
  • After widget creation, using a dictionary index.
  • And use the config() method with keyword attributes.

1) Using keyword arguments when creating the widget

The following illustrates how to use the keyword arguments to set the text option for a label:

import tkinter as tk
from tkinter import ttk


root = tk.Tk()
ttk.Label(root, text='Hi, there').pack()

root.mainloop()Code language: JavaScript (javascript)

Output:

tkinter options

2) Using a dictionary index after widget creation

The following program shows the same label. However, it uses a dictionary index to set the text option for the Label widget:

import tkinter as tk
from tkinter import ttk


root = tk.Tk()

label = ttk.Label(root)
label['text'] = 'Hi, there'
label.pack()

root.mainloop()Code language: JavaScript (javascript)

The following sets the text options for the label:

label['text'] = 'Hi, there'Code language: JavaScript (javascript)

3) Using the config() method with keyword attributes

The following program illustrates how to use the config() method to set the text option for the label:

import tkinter as tk
from tkinter import ttk


root = tk.Tk()

label = ttk.Label(root)
label.config(text='Hi, there')
label.pack()

root.mainloop()Code language: JavaScript (javascript)

Summary

Ttk widgets provide you with three ways to set options:

  • Use keyword arguments at widget creation.
  • Use a dictionary index after widget creation.
  • Use the config() method with keyword attributes.
