PyQt5 – 如何设置单选按钮被按下时的皮肤

在这篇文章中，我们将看到如何在单选按钮被按下并处于未选中状态时为其设置皮肤。默认情况下，当我们按下单选按钮时，有一个蓝色的颜色与之相关，尽管我们可以改变它。皮肤只在指标处于未选中状态和我们按下单选按钮时出现。为了给单选按钮的指示灯添加皮肤，我们必须改变它的样式表代码。下面是样式表的代码。

QRadioButton::indicator:unchecked:pressed
{
border-image : url(image.png);
}

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 skin to unchecked indicator when it get pressed
        self.radio_button.setStyleSheet("QRadioButton::indicator:unchecked:pressed"
                                        "{"
                                        "border-image : url(image.png);"
                                        "}")
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
