PyQt5 – isLeftToRight() method for Check Box
  • Last Updated : 22 Apr, 2020

When we create a check box by default indicator is at left hand side which we call as left to right direction although we can change its direction using setLayoutDirection method. isLeftToRight method is used to check if the layout direction is from left to right or not, it returns True for the default layout direction. It is opposite of isRightToLeft method.

Syntax : checkbox.isLeftToRight()

Argument : It takes no argument.

Return : It returns bool, True if layout direction is left to right else False.

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, 30)
  
        # checking direction
        check = checkbox.isLeftToRight()
  
        # printing the check
        print("Before changing direction  : " + str(check))
  
        # changing position of indicator
        checkbox.setLayoutDirection(Qt.RightToLeft)
  
        # checking direction
        check = checkbox.isLeftToRight()
  
        # printing the check
        print("After changing direction  : " + str(check))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

Output :

Before changing direction  : True
After changing direction  : False
