In this article we will see how to set background color to the pressed indicator when we press it in the intermediate state. Its color should get change when it is pressed and goes back to the default state for other states. 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 do this we have to change the style sheet code for intermediate indicator which is used with the check box object. Below is the style sheet code.
QCheckBox::indicator:indeterminate:pressed
{
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 pressed indicator # when it is in intermediate state checkbox.setStyleSheet("QCheckBox::indicator:indeterminate:pressed" "{" "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()) |
