In this article we will see how to set background image to the pressed indicator when we press it in the intermediate state. Its image should get change when it is pressed and goes back to the default state for other states. By default the check box have only two states, although we can make a third state as well which is not checked or unchecked, it is inbetween both of these states refer as intermediate state with the help of setTristate
method.
In order to do this we have to change the style sheet code for intermediate indicator which is used with the check box object. Below is the style sheet code.
QCheckBox::indicator:indeterminate: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 )
# setting tristate check box
checkbox.setTristate( True )
# changing size of indicator
# adding background image to the pressed indicator
# when it is in intermediate state
checkbox.setStyleSheet( "QCheckBox::indicator"
"{"
"width : 60px;"
"height : 60px;"
"}"
"QCheckBox::indicator:indeterminate::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 ())
