PyQt5 - 悬停时更改未选中状态的单选按钮颜色

在本文中,我们将看到如何在单选按钮处于未选中状态并将鼠标悬停在其上时更改其颜色,默认情况下,没有颜色设置为任何状态或当鼠标悬停在单选按钮上时。

为了将颜色设置为未选中状态的单选按钮并将鼠标悬停在它上面,我们必须更改未选中状态的样式表,当鼠标悬停在单选按钮上时,下面是样式表代码。

QRadioButton::unchecked:hover
{
background-color : red;   
}

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 background color for unchecked state and mouse hover over
        self.radio_button.setStyleSheet("QRadioButton::unchecked:hover"
                                        "{"
                                        "background-color : red;"
                                        "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
