PyQt5 QCommandLinkButton – Going to next state
  • Last Updated : 30 Jun, 2020

In this article we will see how we can go to the next state of the checkable QCommandLinkButton. We can make the command link button checkable with the help of setCheckable method, this will make two states of the command link button which will be checked i.e pressed and unchecked i.e released state. Next state will change the state according to the current state.

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

Syntax : button.nextCheckState()

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, 200, 50)
  
        # making button checkable
        cl_button.setCheckable(True)
          
        # creating a push button
        push = QPushButton("Next State", self)
          
        # setting geometry to the push button
        push.setGeometry(50, 100, 120, 40)
          
        # adding action to the push button
        push.clicked.connect(lambda: next_method())
          
        # method called by push button
        def next_method():
              
            # going to next state
            cl_button.nextCheckState()
    
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
