There are basically two states in check box that are checked or unchecked, although using setTristate method we can add an intermediate state.
checkState method is used to check the state of the check box, it returns CheckState object but when we print it output will be as follows:
- 0 for un-checked state
- 2 for checked state
- 1 for intermediate state
Syntax : checkbox.checkState()
Argument : It takes no argument.
Return : It returns CheckState object
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('Geek ?', self) # setting geometry of check box checkbox.setGeometry(200, 150, 100, 40) # getting the checked state check = checkbox.checkState() # printing the state print("Before check status : ", check) # checking the check box checkbox.setChecked(True) # getting the checked state check = checkbox.checkState() # printing the state print("After check status : ", check) # exiting the program sys.exit() # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
Before check status : 0 After check status : 2
