In this article we will see how we can get the toggled signal of the QCommandLinkButton. This signal is emitted whenever a checkable command link button changes its state. 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 with the help of setChecked method.
In order to do this we use toggled method with the command link button object
Syntax : button.toggled.connect(method)
Argument : It takes method as argument
Action Performed : It calls the method when the clicked signal is emitted
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"))
# 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 ())
