In this article we will see how we can add extra widget to the QColorDialog. Extra widget is like extra functionality added to the color dialog, it can be label push button or any thing else, below is how the extra widget will look like


Implementation Steps: 
1. Create a main window class 
2. Inside the main window class create a QColorDialog object 
3. Add properties to the color dialog 
4. Create a label and set its properties 
5. Add this label to the layout of the dialog object 
6. Execute the dialog 
7. Delete the main window class

Below is the implementation 


# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
class Window(QMainWindow):
    def __init__(self):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 500, 400)
        # calling method
        # showing all the widgets
    # method for components
    def UiComponents(self):
        # creating a QColorDialog object
        dialog = QColorDialog(self)
        # setting custom colors
        dialog.setCustomColor(3, Qt.yellow)
        # executing the dialog
        # dialog.exec_()
        # creating label
        label = QLabel("Geeks for Geeks", self)
        # making label multi line
        # setting stylesheet of the label
                            "border : 5px solid black;"
        # getting the custom color
        color = dialog.customColor(4)
        # setting graphic effect to the label
        graphic = QGraphicsColorizeEffect(self)
        # setting color to the graphic
        # setting graphic to the label
        layout = dialog.layout()
        # getting dialog layout
        # value = dialog.layout()
        # setting text to the label
        # label.setText("Layout : " + str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
