In this article we will see how to set background color to the check box for label part when mouse hover and it is in currently intermediate state. Intermediate state is a state inbetween checked and unchecked state it is the third state which is created with the help of setTristate method. 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 intermediate state when mouse hover over it. Below is the style sheet code.
QCheckBox::indeterminate:hover { background-color : cyan; }
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 tristate check box
checkbox.setTristate( True )
# setting geometry of check box
checkbox.setGeometry( 200 , 150 , 100 , 30 )
# adding background color to the check box label part
# when it is in intermediate state when mouse hover over it
checkbox.setStyleSheet("QCheckBox:indeterminate:hover"
"{"
"background - color : cyan;"
"}")
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
