PyQt5 - 检查单选按钮的布局方向是否从右到左

在本文中，我们将看到如何检查单选按钮的布局方向是否是从右到左。默认情况下，单选按钮的对齐方式是从左到右，尽管在setLayoutDirection的帮助下我们可以更改其对齐方式。从右到左的方向基本上告诉指标在右侧，文本部分在左侧。

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.

编程需要懂一点英语

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(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())

输出：
