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()) |
Output :
