Changing the Background Color of a Tkinter Window using Colorchooser Module

Tkinter is a popular Python GUI tool that is commonly used for creating desktop applications. One of the key features of Tkinter is its ability to create windows and dialogs with a wide range of customization options, such as changing the background color of a window.

In this article, we will be discussing the Colorchooser module in Tkinter, which allows users to select a color and apply it to their window as the background color.

The Colorchooser Module

The Colorchooser module is a built-in module in Tkinter that allows users to select a color from a dialog box. The module is easy to use and provides users with a wide range of color options.

To use the Colorchooser module, we simply need to import it into our Python program using the following code:

from tkinter import colorchooser

After importing the module, we can create an instance of the Colorchooser dialog box using the askcolor() method:

color = colorchooser.askcolor()

The askcolor() method will return a tuple containing the RGB value of the selected color as well as the hexadecimal value of the color.

Changing the Background Color of a Tkinter Window

Now that we have an understanding of the Colorchooser module in Tkinter, we can use it to change the background color of a Tkinter window.

First, we need to create a new Tkinter window using the Tk() method:

from tkinter import *

root = Tk()

Next, we can set the geometry of the window using the geometry() method:

root.geometry("500x500")

This will create a window with a size of 500px by 500px.

Now, we can add a label to the window using the Label() method:

label = Label(root, text="Hello World!")
label.pack()

This will add a label with the text “Hello World!” to the window.

To change the background color of the window using the Colorchooser module, we can create a button that will open the Colorchooser dialog box when clicked:

button = Button(root, text="Choose Color", command=set_color)
button.pack()

In this code, we have created a button with the text “Choose Color” and assigned a command called set_color to it. The set_color command will be responsible for opening the Colorchooser dialog box.

To create the set_color command, we can use the following code:

def set_color():
    color = colorchooser.askcolor()[1]
    root.configure(background=color)

In this code, we have created a new function called set_color() that will be called when the “Choose Color” button is clicked. Within this function, we use the askcolor() method to open the Colorchooser dialog box and retrieve the hexadecimal value of the selected color.

We then use the configure() method to set the background color of the Tkinter window to the selected color.

Full Code

Here is the full code to create a Tkinter window and add a “Choose Color” button that will allow users to change the background color of the window using the Colorchooser module:

from tkinter import *
from tkinter import colorchooser

root = Tk()
root.geometry("500x500")
label = Label(root, text="Hello World!")
label.pack()

def set_color():
    color = colorchooser.askcolor()[1]
    root.configure(background=color)

button = Button(root, text="Choose Color", command=set_color)
button.pack()

root.mainloop()

Conclusion

In this article, we have learned how to use the Colorchooser module in Tkinter to allow users to select a color and apply it as the background color of a Tkinter window. We also discussed how to create a new Tkinter window, add a label, and create a button that can be used to open the Colorchooser dialog box. This is a valuable tool for Python developers who want to create customized desktop applications with user-friendly interfaces.
