PyQt5 – 按下时选中的 RadioButton 指示器的外观

在本文中，我们将看到当单选按钮被按下并处于选中状态时，我们如何将皮肤设置为单选按钮的指示器。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。皮肤仅在处于选中状态以及我们按下单选按钮时才会出现在指示器上。

为了给单选按钮的指示器添加皮肤，我们必须更改它的样式表代码。下面是样式表代码。

QRadioButton::indicator:checked:pressed
{
border-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 skin to checked indicator when it get pressed
        self.radio_button.setStyleSheet("QRadioButton::indicator:checked:pressed"
                                        "{"
                                        "border-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 ：
