PyQt5 – Set Skin to intermediate CheckBox when pressed

In this article we will see how we can set skin to check box when it is already in intermediate (indeterminate) state and when it get pressed. By default there is no skin associated to the check box, skin is basically background image that can adjust it self according to the size of check box.

Intermediate or indeterminate state is the third state of the check box which can be added with the help of setTristate method.

In order to do add skin to the intermediate check box when it get pressed we have to edit the style sheet code, below is the style sheet code.

QCheckBox::indeterminate:pressed
{
border-image : url(image.png);
}

Below is the implementation.

# importing libraries
from PyQt5.QtWidgets 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
        checkbox1 = QCheckBox('Geek ?', self)

        # setting geometry of check box
        checkbox1.setGeometry(200, 150, 100, 40)

        # setting tri-state check box
        checkbox1.setTristate(True)

        # changing style sheet code of check box
        # adding skin to indeterminate check box when it get pressed
        checkbox1.setStyleSheet("QCheckBox::indeterminate:pressed"
                                "{"
                                "border-image : url(image.png);"
                                "}")


# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
