In this article we will see how to set background color to a check box when it is in intermediate state and mouse hover over it. By default the check box have only two states although we can make a third state as well which is not checked or unchecked it is inbetween both of these states refer as intermediate state with the help of setTristate
method.
In order to add background color to indicator in intermediate state we have to change the style sheet of the indicator for intermediate state and when cursor hover over it, below is the style sheet code.
QCheckBox::indicator:indeterminate:hover { background-color : blue; }
Below is the implementation.
# 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 )
# creating tri-state check box
checkbox.setTristate( True )
# adding background color to the indicator
# when it is in intermediate state and cursor hover over it
checkbox.setStyleSheet( "QCheckBox::indicator:indeterminate:hover"
"{"
"background-color : blue;"
"}" )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
