In this article we will see how we can get the icon changed signal of the QCommandLinkButton. This signal is emitted when the command link button’s icon has changed. By default a arrow is set as the icon of the command link button although we can change this any time with the help of setIcon method.
In order to do this we use windowIconChanged method with the command link button object
Syntax : button.windowIconChanged.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, 60) # creating label label = QLabel(self) # setting label geometry label.setGeometry(50, 100, 200, 40) # making label multiline label.setWordWrap(True) # making it checkable cl_button.setCheckable(True) # text text = "Icon Changed Signal Emitted" # icon changed signal cl_button.windowIconChanged.connect(lambda: label.setText(text)) # icon icon = QIcon('logo.png') # changing icon cl_button.setWindowIcon(icon) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
