PyQt5 – 如何在鼠标悬停时将皮肤设置为选中的 RadioButton 指示器

在本文中，我们将看到当鼠标悬停在单选按钮上并处于选中状态时，如何将皮肤设置为单选按钮的指示器。默认情况下，没有皮肤或图像与之关联，尽管我们可以为其设置皮肤。皮肤仅在处于选中状态以及将鼠标悬停在单选按钮上时才会出现在指示器上。

为了给单选按钮的指示器添加皮肤，我们必须更改它的样式表代码。下面是样式表代码。

QRadioButton::indicator: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 to checked indicator when mouse hover it
        self.radio_button.setStyleSheet("QRadioButton::indicator: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())
