PyQt5 – Unchecked background color of check box when hover

0 0 1 minute read

In this article we will see how to set background color to the check box for label part when mouse hover over it and it is in currently unchecked state. In order to do this we have to change the style sheet of the check box and have to add the background color for the unchecked state when mouse hover over it. Below is the style sheet code.

QCheckBox::unchecked:hover
{
background-color : pink;
}

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
        checkbox = QCheckBox('Geek ?', self)
 
        # setting geometry of check box
        checkbox.setGeometry(200, 150, 100, 30)
 
        # adding background color to the check box label part
        # when it is in unchecked state when mouse hover over it
        checkbox.setStyleSheet("QCheckBox::unchecked:hover"
                               "{"
                               "background-color : pink;"
                               "}")
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
