PyQt5 – Background color of intermediate 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 intermediate state. 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 add background color to indicator in intermediate state we have to change the style sheet of the indicator for intermediate state below is the style sheet code.

QCheckBox::indicator:indeterminate
{
background-color : blue;
}

Note : In order to see this we have to make third state first without that it will not work.

Below is the implementation.

App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
