  • Last Updated : 26 Jun, 2020

In this article we will see how we can get the pressed signal of the QCommandLinkButton. This signal is emitted when the button is pressed down. There are two stages when button is clicked first is the pressed state and second is the release state.

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

Syntax : button.pressed.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, 200, 50)
  
        # creating label
        label = QLabel("GeeksforGeeks", self)
  
        # setting label geometry
        label.setGeometry(100, 100, 200, 40)
  
        # pressed signal
        # set text to the label
        cl_button.pressed.connect(lambda: label.setText("Pressed Signal Emitted"))
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
