In this article we will see how to set color to the check box i.e to the label part when the check box is in intermediate state. We can set background color to the check box but that will remain same for all the states. 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 set background color for the intermediate state we have to change the style sheet of the label part in the indeterminate(intermediate) state. Below is the style sheet code.
QCheckBox::indeterminate { 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 pressed check box label part # when it is in intermediate state checkbox.setStyleSheet("QCheckBox:indeterminate" "{" "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 ()) |
