PyQt5 – Change Color of Check Box indicator

Check box basically have two components that are label and a indicator. By default there is no specific color is set to the indicator although we can change the color of the indicator. Below is the representation of normal indicator vs the colored indicator.

In order to do this we have to add the background color to the indicator of the check box which can be done using style sheet of indicator below is the style sheet code which can be used with the check box object.

QCheckBox::indicator
{
background-color : lightgreen;
}

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):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 600, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for widgets
    def UiComponents(self):

        # creating the check-box
        checkbox = QCheckBox('Geek ?', self)

        # setting geometry of check box
        checkbox.setGeometry(200, 150, 100, 30)

        # adding background color to indicator
        checkbox.setStyleSheet("QCheckBox::indicator"
                               "{"
                               "background-color : lightgreen;"
                               "}")



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
