In this article we will see how we can toggle the QCommandLinkButton. Toggling means to change the state of the command link button, when it is toggle, toggled signal is emitted. By default it is not checkable although we can make it checkable any time with the help of setCheckable
method.
In order to do this we use toggle
method with the command link button object
Syntax : button.toggle()
Argument : It takes no argument
Return : It return None
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 , 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 )
# toggle signal
# printing message
cl_button.toggled.connect( lambda : print ( "Toggled Signal Emitted" ))
# toggle the button
cl_button.toggle()
cl_button.toggle()
cl_button.toggle()
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())

Output :
