PyQt5 – 未选中状态下被按下的单选按钮的背景图片

在这篇文章中，我们将看到如何设置未选中状态下被按下的单选按钮的背景图片，默认情况下，任何状态或单选按钮被按下时都没有设置图片。为了给未选中状态的单选按钮设置背景图像，我们必须改变未选中状态和单选按钮被按下时的样式表，下面是样式表代码。

RadioButton::unchecked:pressed
{
background-image : url(image.png);   
}

以下是实施情况

# 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 for unchecked state when pressed
        self.radio_button.setStyleSheet("QRadioButton::unchecked: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:
