PyQt5 - 右侧的单选按钮指示器

在本文中，我们将看到如何在右侧制作单选按钮的指示器。默认情况下，当我们创建单选按钮时，其指示器位于左侧。单选按钮的指示器是圆形的可检查部分，表示它是否被选中。

下面是普通单选按钮与指示器在右侧的单选按钮。

In order to make this type of widget we have to do the following –

1. Create a radio button using QRadioButton class.
2. Change its layout direction with the help of setLayoutDirection by default it is left to right, set it to right to left.

下面是实现。

# 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("Radio Button", self)
  
        # setting geometry of radio button
        radio_button.setGeometry(200, 150, 100, 40)
  
        # setting layout direction of radio button
        radio_button.setLayoutDirection(Qt.RightToLeft)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
