PyQt5 QCommandLinkButton – Toggled Signal
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 librariesfrom PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGuifrom 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 mesage cl_button.toggled.connect(lambda: print("Toggled Signal Emitted")) # making its state checked cl_button.setChecked(True) # create pyqt5 appApp = QApplication(sys.argv) # create the instance of our Windowwindow = Window() # start the appsys.exit(App.exec()) |
Output :
