Check box is basically divided into two components one is the indicator which is on the left side by default and other is the check box itself i.e the label part which has text on it. In this article we will see how to set image to a indicator. Below is the representation of normal indicator of check box vs the check box with image on indicator. 
In order to set image to a indicator we have to change the style sheet of the indicator of the check box. Below is the style sheet code which is used with the check box object.
QCheckBox::indicator
{
background-image :url(image.png);
}
Below is the implementation.
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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, 80) # setting stylesheet # adding background image to indicator of check box # and changing width and height of indicator checkbox.setStyleSheet("QCheckBox::indicator" "{" "background-image : url(image.png);" "width :40px;" "height : 40px;" "}")# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
