PyQt5 – 为单选按钮设置边框

在这篇文章中，我们将看到如何为单选按钮设置边框。默认情况下，单选按钮是没有边框的，尽管我们可以设置它。下面是普通的单选按钮和有边框的单选按钮的对比图。

为了做到这一点，我们必须改变与单选按钮相关的样式表，并且必须为它添加边框。下面是样式表的代码。

QRadioButton
{
border : 2px solid green;
}

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
        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")
  
        # setting style sheet associated with the radio button
        # adding border to the radio button
        radio_button.setStyleSheet("QRadioButton"
                                   "{"
                                   "border : 2px solid green"
                                   "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
