PyQt5 – Set Skin to indeterminate Check Box

In this article we will see how we can set skin to the check box when it is in indeterminate (intermediate) state, skin i.e image only appear when check box comes to indeterminate state. Skin is basically a background image which adjust it self according to the size of the check box.

Indeterminate (intermediate) state is the third state of the check box which is in-between checked and unchecked state, it can be created with the help of setTristate method.

In order to add skin to the indeterminate check box we have to change the style sheet code it, below is the style sheet code.

QCheckBox::indeterminate
{
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
        checkbox1.setStyleSheet("QCheckBox::indeterminate"
                                "{"
                                "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 :
