PyQt5 – 当鼠标悬停在单选按钮上时皮肤

在本文中，我们将看到当鼠标悬停在单选按钮上时如何为单选按钮设置皮肤，默认情况下，单选按钮没有关联图像/皮肤。皮肤是一个背景图片，可以根据单选按钮的大小自行调整。

为了在鼠标悬停在单选按钮上时为单选按钮添加皮肤，我们必须更改单选按钮的样式表代码，下面是样式表代码。

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

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
        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 for radio button when mouse hover over it
        self.radio_button.setStyleSheet("QRadioButton::hover"
                                        "{"
                                        "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())

输出 ：
