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 :
Toggled Signal Emitted Toggled Signal Emitted Toggled Signal Emitted
