In this article we will see how we can check if the checkable QCommandLinkButton checked or unchecked, 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 isChecked method with the command link button object
Syntax : button.isChecked()
Argument : It takes no argument
Return : It returns bool
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) # making its state checked cl_button.setChecked(True) # creating label label = QLabel("neveropen", self) # setting label geometry label.setGeometry(100, 100, 200, 40) # making label multiline label.setWordWrap(True) # checking if button is in checked state value = cl_button.isChecked() # setting text to the label label.setText("Checked ? " + str(value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
