Change Background Color GUI in Tkinter

Change background color GUI in tkinter. This program will create a new pop up window and ask the user to select the color as a background in the output window. 

Changing color in word or notepad is not that difficult but it matters when it comes to programming especially GUI programming in Tkinter python. For image and picture files with a colour defined for the image background, the Background Color information is saved. 

In most situations, the background colour is represented by an RGB triplet or a hexadecimal value. A backdrop is what is below another item when referring to a place or position. The backdrop colour in “this example Text” is red, while the yellow text is in the forefront.

Uses of Tkinter Python

We can create new applications such as a music player, pdf reader, and other things using these basic Tkinter python gui programs. 

The background colour of the Python application is being changed in this example. We may also alter or fix the application’s window size, such as the screen resolution, which is 400*400 in this case.

The visual dimensions of any display are described by monitor resolution. Monitor resolution is expressed in terms of width and height and is made up of a certain number of pixels.

This display has a resolution of 1920 x 1080 on a monitor with an industry-standard Full HD 1080p resolution.

mw.mainloop in tkinter

Python calls mainloop() to start the Tkinter event loop. This method waits for events such as button clicks or keypresses and prevents any further code from running until the window on which it is called is closed. 

mainloop() is a method in the main window that runs the code we want to run in an application. It will run indefinitely until the user exits the window or until it receives any input from the user. With this program we can execute change background color GUI in tkinter

import tkinter as tk
from tkinter.colorchooser import *

color = askcolor()
print(color[1])
mw.configure(background=color[1])
mw = tk.Tk()
mw.title('COLOR ME!!!')
mw.geometry("400x400")
mw.resizable(0, 0)
tk.Button(text='Choose your favourite color',
command=getColor).pack()
mw.mainloop()
