PyQt5 - 单选按钮中的虚线边框指示器

在本文中，我们将看到如何为单选按钮的指示器制作虚线边框。默认情况下，单选按钮指示器是圆形的，并具有纯黑色边框。

为了给单选按钮的指示器添加虚线边框，我们必须更改与单选按钮关联的指示器的样式表代码，下面是样式表代码。

QRadioButton::indicator
{
border : 2px blue;
border-style : dotted;
}

注意：当我们更改指示器样式表时，它会失去其圆形形状。

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
        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 to radio button
        # setting border width and color to indicator
        # setting border style to dotted to indicator
        radio_button.setStyleSheet("QRadioButton::indicator"
                                   "{"
                                   "border : 2px green;"
                                   "border-style : dotted;"
                                   "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
