setChecked method is used to change the state of check box. By default it is un-checked after clicking on the check box widget its states get changed into checked, but with the help of setChecked method we can do it directly without clicking it.
Syntax : checkbox.setChecked(True)
Argument : It takes bool as argument.
Action performed : It will change the state of check box.
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('Check Box', self) # setting geometry of check box checkbox.setGeometry(200, 150, 100, 30) # setting check box state to checked checkbox.setChecked(True) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
