In this article we will see how to set an action to a check box. Adding action to a check box means when the check box is checked it should perform some task. In order to do so we will use stateChanged.connect method, when the state of the checkbox is changed it will connect it to the action.
Syntax : checkbox.stateChanged.connect(method_name)
Argument : It takes method name as argument.
Action performed : It will call the method when check box will be checked
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, 600, 400) # calling method self.UiComponents() # showing all the widgets self.show() # method for widgets def UiComponents(self): # creating the check-box checkbox = QCheckBox('Show Label', self) # setting geometry of check box checkbox.setGeometry(200, 150, 100, 30) # adding action to check box checkbox.stateChanged.connect(self.action) # creating action method def action(self): # creating label self.label = QLabel("Check Box is checked", self) # moving the label self.label.move(200, 200) # adjusting the size of label self.label.adjustSize() # showing the label self.label.show() # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
When checkbox will be checked window will look like this
