PyQt5 – 如何将图标添加到单选按钮？

在本文中，我们将了解如何将徽标设置为单选按钮。默认情况下，单选按钮没有设置徽标，虽然我们可以为单选按钮设置图标，这类似于将图标设置为主窗口，但与主窗口不同的是，单选按钮的图标出现在指示器和文本部分之间。

下面是默认单选按钮的外观与带有图标的单选按钮的外观。

In order to add icon to the radio button we have to do the following:

1. Create a radio button.
2. Load the icon and create the object with the help of QIcon class
3. Set the object of QIcon as icon to the radio button with the help of setIcon method.

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")
  
        # creating object of QICon and loading the icon
        icon = QIcon('logo.png')
          
        # setting icon to radio button
        radio_button.setIcon(icon)
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
