In this article we will see how to set background image to a indicator for unchecked check box. By default there is no background image set to the indicator. In order to set background image to the indicator for only unchecked state we have to change the style sheet of the indicator for unchecked state. Below is the style sheet code.
QCheckBox::indicator:unchecked { background-image : url(image.png); }
Below is the implementation.
Python3
# 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
checkbox.setStyleSheet("QCheckBox::indicator"
"{"
"width : 60px ;"
"height : 60px ;"
"}"
"QCheckBox::indicator:unchecked"
"{"
"background - image : url(indicator_image.png);"
"width : 60px ;"
"height : 60px ;"
"}")
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
