PyQt5 QCommandLinkButton – How to set Check State

In this article we will see how we can make the checkable QCommandLinkButton checked or unchecked, by default it is not checkable although we can make it checkable any time with the help of setCheckable method. Also when it is checkable its state is unchecked although we can programmatically make its state checked.

In order to do this we use setChecked method with the command link button object

Syntax : button.setChecked(True)

Argument : It takes bool as argument

Return : It returns None

Below is the implementation

        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 500, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
  
    # method for components
    def UiComponents(self):
  
  
        # creating a command link button
        cl_button = QCommandLinkButton("Press", self)
  
        # setting geometry
        cl_button.setGeometry(250, 100, 150, 50)
  
        # making it checkable
        cl_button.setCheckable(True)
  
        # making its state checked
        cl_button.setChecked(True)
  
         
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
