Introduction:

Colors play an important role in any GUI application, and the ability to select and save colors can be a useful feature for many applications. In this tutorial, we will be creating a color picker using the Tkinter library in Python. This color picker will allow users to select a color and save it for later use.

Importing necessary libraries

The first step in creating our color picker is to import the necessary libraries. In this case, we will be using the Tkinter library to create the GUI and the colorchooser library to create the color picker dialog.

import tkinter as tk
from tkinter import colorchooser

Creating the color picker function

The next step is to create a function that will handle the selection and saving of the color. This function will be triggered when the user clicks the “Select Color” button.

def select_color():
    # Open the color picker dialog
    color = colorchooser.askcolor()[1]

    # Save the selected color
    with open("selected_color.txt", "w") as file:
        file.write(color)

    # Update the color label
    color_label.config(text=color)

This function opens the color picker dialog, saves the selected color to a file, and updates the color label with the selected color.

Creating the window and widgets

The next step is to create the window and the necessary widgets. We create a new window using the Tk() class, and set the title to “Color Picker”. We also create a button to trigger the color selection, and a label to display the selected color.

# Create a new window
root = tk.Tk()
root.title("Color Picker")

# Create a button to trigger the color selection
select_color_button = tk.Button(root, text="Select Color", command=select_color)

# Create a label to display the selected color
color_label = tk.Label(root, text="")

Organizing the layout:

The layout of the widgets is organized using the grid method, which allows for precise positioning of the widgets within the window.

# Organize the layout using the grid method
select_color_button.grid(row=0, column=0)
color_label.grid(row=1, column=0)

Running the program

Finally, we run the program using the root.mainloop() function which will keep the program running and waiting for user input until the window is closed.

root.mainloop()

Full Code

import tkinter as tk
from tkinter import colorchooser

def select_color():
    # Open the color picker dialog
    color = colorchooser.askcolor()[1]

    # Save the selected color
    with open("selected_color.txt", "w") as file:
        file.write(color)

    # Update the color label
    color_label.config(text=color)

# Create a new window
root = tk.Tk()
root.title("Color Picker")

# Create a button to trigger the color selection
select_color_button = tk.Button(root, text="Select Color", command=select_color)

# Create a label to display the selected color
color_label = tk.Label(root, text="")

# Organize the layout using the grid method
select_color_button.grid(row=0, column=0)
color_label.grid(row=1, column=0)

root.mainloop()

Conclusion

This is a basic example of how to create a color picker using Tkinter. There are many ways to improve and expand upon this program, such as adding error handling, user input validation, and additional features. With the knowledge gained from this tutorial, you can start creating your own Tkinter based color picker applications. Please note that this is a basic example, in real-world applications you should handle the exception if the file is not present, and provide an option for the user to save the selected color as a variable.

In this code, we first import the necessary libraries, tkinter and colorchooser. Then we create the function select_color() that will handle the selection and saving of the color. A button is created with the command select_color, so when it is clicked it will trigger the function. The selected color is saved in a file named selected_color.txt. The color label is created to display the selected color. The layout of the widgets is organized using the grid method. The infinite loop root.mainloop() is used to run the Tkinter program.
