PyQt5 - 按下时单选按钮的选中指示器的背景颜色

在本文中,我们将看到如何为处于选中状态并被按下的单选按钮的指示器设置背景颜色。默认情况下,蓝色与指示器相关联,尽管我们可以更改此颜色。

为了在指示器单选按钮处于选中状态并被按下时为其添加背景颜色,我们必须更改样式表代码。下面是样式表代码。

QRadiobutton::indicator:checked:pressed
{
background-color : lightgreen;
}

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 color to checked indicator when it get pressed
        self.radio_button.setStyleSheet("QRadioButton::indicator:checked:pressed"
                                        "{"
                                        "background-color : lightgreen;"
                                        "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
