PyQt5 – Background color of un-checked indicator in Check Box

In this article we will see how to set background color to an indicator of check box when it is in unchecked state. When checked it will revert back to its default form and for unchecked state we can set the background color.

In order to add background color to indicator in un-checked state we have to change the style sheet of the indicator for un-checked state below is the style sheet code.

QCheckBox::indicator:unchecked
{
background-color : yellow;
}

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 the indicator for unchecked state
        checkbox.setStyleSheet("QCheckBox::indicator:unchecked"
                               "{"
                               "background-color : yellow;"
                               "}")

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

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

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

Output :
