PyQt5 – 矩形指示器单选按钮

在这篇文章中，我们将看到如何制作单选按钮的矩形指示器。默认情况下，单选按钮的指示器是圆形的。

下面是普通的单选按钮和一个指示器为矩形的单选按钮的表现。

为了做到这一点，我们必须改变与单选按钮对象相关的指示器的样式表代码，下面是样式表代码。

QRadioButton::indicator
{
border : 1px solid black;
width : 20px;
height : 10px;
border-radius : 1px;
}

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
        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 border to indicator of thickness 1px and of black color
        # and width and height and the border radius equal to thickness of border
        self.radio_button.setStyleSheet("QRadioButton::indicator"
                                        "{"
                                        "border : 1px solid black;"
                                        "width : 20px;"
                                        "height : 10px;"
                                        "border-radius : 1px;"
                                        "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
