PyQt5 – Check if layout direction of radio button is right to left

  • Last Updated : 22 Apr, 2020

In this article we will see how to check if the layout direction of radio button is right to left or not. By default alignment of radio button is left to right although with the help of setLayoutDirection we can change its alignment. Right to left direction is basically tells that indicator is on the right side and text part is on the left side.

Overview of the implementation :

1. Create a radio button
2. Set direction to the radio button (optional)
3. Create a label which shows if the alignment is right to left or not
4. Check the alignment with the help of isRightToLeft and save it in the variable
5. Set the answer to the label with the help of setText method.

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 a radio button
        radio_button = QRadioButton(self)
  
        # setting geometry of radio button
        radio_button.setGeometry(200, 150, 120, 40)
  
        # setting text to radio button
        radio_button.setText("Radio Button")
  
        # setting direction
        radio_button.setLayoutDirection(Qt.RightToLeft)
  
        # creating label to show output
        label = QLabel(self)
  
        # changing position of label
        label.move(200, 200)
  
        # check if direction is right to left
        check = radio_button.isRightToLeft()
  
        # setting output text to label
        label.setText(" Is direction is right to left :" + str(check))
  
        # adjusting the size of label
        label.adjustSize()
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
