PyQt5 - 单选按钮的虚线边框

在本文中，我们将看到如何为单选按钮创建虚线边框。默认情况下，没有与单选按钮关联的边框，尽管我们可以为其创建边框。我们也可以编辑样式表来制作虚线边框。

下面是普通边框单选按钮与虚线边框单选按钮的表示。

为此，我们必须更改与单选按钮关联的样式表。

QRadioButton
{
border : 2px green;
border-style :dotted;
}

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
        # setting border style to dotted
        radio_button.setStyleSheet("QRadioButton"
                                   "{"
                                   "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())
