PyQt5 QCommandLinkButton – Released Signal

0 0 1 minute read

In this article we will see how we can get the released signal of the QCommandLinkButton. This signal is emitted when the button is released. 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 released method with the command link button object

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