PyQt5 – 如何在鼠标悬停时将皮肤设置为选中的单选按钮

在本文中，我们将看到当鼠标悬停在单选按钮上并且它处于选中状态时如何为单选按钮设置皮肤。皮肤基本上是背景图像，可以根据单选按钮的大小自行调整。此皮肤仅在鼠标悬停在单选按钮上且处于选中状态时才会出现。

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