PyQt5 – Skin to intermediate CheckBox when mouse hover

In this article we will see how we can set skin to check box who is in intermediate state and mouse hover over it. By default there is no image is associated with the check box, this skin appear only when mouse hover intermediate check box. Intermediate (indeterminate) state is the third state which is in-between checked and unchecked state which can added to check box with the help of setTristate method. In order to set skin we have to the style sheet code of check box, below is style sheet code.

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

Below is the implementation. 

Python3

# 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
        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 mouse hover over it
        checkbox1.setStyleSheet("QCheckBox::indeterminate:hover"
                                "{"
                                "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 :
