PyQt5 - 悬停时设置选中的复选框指示器背景颜色

在本文中,我们将看到如何在复选框处于选中状态并将鼠标悬停时将背景颜色设置为复选框的指示器。为了做到这一点,我们必须在选中状态的复选框中更改指示器的样式表,并在鼠标移过它时更改。

下面是与复选框对象一起使用的样式表代码。

QCheckBox::indicator:checked: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 the check-box
        checkbox = QCheckBox('Geek ?', self)
  
        # setting geometry of check box
        checkbox.setGeometry(200, 150, 100, 30)
  
        # adding background color to the indicator
        # when it is in checked state and mouse hover over it
        checkbox.setStyleSheet("QCheckBox::indicator:checked: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 :
