PyQt5 – Setting background image to pressed indicator from unchecked Check Box

In this article we will see how we can add background image to the pressed indicator which was initially in the unchecked state. In order to do this we have to change the style sheet code associated with the check box object and have to add background image to the indicator of unchecked state when it get pressed.

Below is the style sheet code.

QCheckBox::indicator:unchecked:pressed
{
background-image : url(image.png);
}

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, 60)

        # changing size of indicator
        # adding background image to the indicator
        # when it is in unchecked state and when it get pressed
        checkbox.setStyleSheet("QCheckBox::indicator"
                               "{"
                               "width : 60px;"
                               "height : 60px;"
                               "}"
                               "QCheckBox::indicator:unchecked:pressed"
                               "{"
                               "background-image : url(indicator_image.png);"
                               "}")


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

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

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

Output :
