PyQt5 - 按下时将背景图像设置为单选按钮指示器

在本文中,我们将看到如何将背景图像设置为单选按钮被按下时的指示器。默认情况下,当我们按下单选按钮时,虽然我们可以更改它,但它会显示为蓝色。只有当我们按下单选按钮时,背景图像才会出现在指示器上。

为了将背景图像添加到单选按钮的指示器,我们必须更改它的样式表代码。下面是样式表代码。

QRadioButton::indicator:pressed
{
background-image : url(image.png);
}

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
        self.radio_button = QRadioButton(self)
  
        # setting geometry of radio button
        self.radio_button.setGeometry(200, 150, 120, 40)
  
        # setting text to radio button
        self.radio_button.setText("Radio Button")
  
        # changing style sheet code of radio button
        # setting background image indicator when it get pressed
        self.radio_button.setStyleSheet("QRadioButton::indicator:pressed"
                                        "{"
                                        "background-image : url(image.png);"
                                        "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
