PyQt5 – 为单选按钮的指示器设置颜色

在本文中,我们将了解如何为单选按钮的指示器设置颜色。默认情况下,白色与指示器相关联,尽管我们可以借助与其相关联的指示器样式表来更改颜色。

为了改变指示器的颜色,我们在样式表中为指示器设置了背景颜色。下面是执行此操作的样式表代码。

QRadioButton
{
background-color : lightgreen;
}

注意:当我们更改与指标关联的样式表代码时,指标的形状会设置为正方形。

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 associated with the radio button
        # adding color to the indicator
        radio_button.setStyleSheet("QRadioButton::indicator"
                                   "{"
                                   "background-color : lightgreen"
                                   "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
