PyQt5 – 为RadioButton的未选中指标设置皮肤

在这篇文章中，我们将看到当单选按钮处于未选中状态时，我们如何给它的指示器设置皮肤。默认情况下，虽然我们可以为它添加皮肤，但没有图像与选中状态相关联。皮肤基本上是一个背景图片，它可以根据指示器的大小来调整自己。这个皮肤只在单选按钮处于未选中状态时出现。为了做到这一点，我们必须改变单选按钮的样式表，下面是样式表的代码。

QRadioButton::indicator:unchecked
{
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
        self.radio_button.setStyleSheet("QRadioButton::indicator:unchecked"
                                        "{"
                                        "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())
