PyQt5 - 悬停时未选中的复选框背景

在本文中，我们将看到如何在鼠标悬停时为标签部分的复选框设置背景颜色，并且它处于当前选中状态。

为此，我们必须更改复选框的样式表，并且必须在鼠标悬停在复选框上时为选中状态添加背景颜色。下面是样式表代码。

QCheckBox::checked:hover
{
background-color : pink;
}

下面是实现。

Python3

# 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 the check-box
        checkbox = QCheckBox('Geek ?', self)
 
        # setting geometry of check box
        checkbox.setGeometry(200, 150, 100, 30)
 
        # adding background color to the check box label part
        # when it is in checked state when mouse hover over it
        checkbox.setStyleSheet("QCheckBox::checked:hover"
                               "{"
                               "background-color : pink;"
                               "}")
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出 ：
