Python Tkinter Colorchooser: Effortlessly choose and display colors

Last update on December 21 2024 07:48:13 (UTC/GMT +8 hours)

Write a Python GUI program to create a Colorchooser widget to select a color using tkinter module.

Sample Solution:

Python Code:

import tkinter as tk
from tkinter import colorchooser

def choose_color():
    color = colorchooser.askcolor(title="Select a Color")
    if color[1]:
        selected_color_label.config(text=f"Selected Color: {color[1]}")
        color_frame.config(bg=color[1])

parent = tk.Tk()
parent.title("Colorchooser Example")

# Create a button to open the color chooser dialog
choose_color_button = tk.Button(parent, text="Choose a Color", command=choose_color)
choose_color_button.pack(padx=20, pady=20)

# Create a label to display the selected color
selected_color_label = tk.Label(parent, text="Selected Color:", font=("Helvetica", 10))
selected_color_label.pack()

# Create a frame to display the selected color
color_frame = tk.Frame(parent, width=100, height=50)
color_frame.pack(padx=20, pady=20)

parent.mainloop()

Explanation:

In the exercise above -

• Import 'tkinter' as 'tk' and 'colorchooser' for creating GUI components and accessing the color chooser dialog.
• Define a function "choose_color()" that opens the color chooser dialog using colorchooser.askcolor(). As soon as a color is selected and the dialog is closed, it returns a tuple containing the color's RGB format and its name. We update the label and frame with the selected color.
• Create the main window using tk.Tk() and set its title.
• The 'choose_color_button' button will call the "choose_color()" function when clicked.
• Create a label named 'selected_color_label' to display the selected color.
• Create a frame named 'color_frame' to display the selected color as a background color.
• The main event loop, root.mainloop(), starts the Tkinter application.
