PyQt5 – 单选按钮的点状边界

在这篇文章中，我们将看到如何为单选按钮创建点状的边框。默认情况下，单选按钮没有边框，尽管我们可以为它创建边框。我们也可以编辑样式表来制作点状边框。下面是普通边框的单选按钮与点状边框的单选按钮的对比。

为了做到这一点，我们必须改变与单选按钮相关的样式表。

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

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 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())
