PyQt5 – Changing size of Indicator in Check Box

In this article we will see how to change the size of indicator. Indicator is the part of check box although if we change the size of check box with the help of resize method or setGeometry method, but it will change the size of check box but not the indicator.

In order to change the size of indicator we have to change the height and width in the style sheet of the indicator which is used with check box object. Below is the style sheet code.

QCheckBox::indicator
{
width : 40px;
height : 40px;
}

Below is the implementation.

                               "height : 40px;"
                               "}")
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
