PyQt5 - 鼠标悬停时设置复选框指示器的皮肤

在本文中，我们将看到当鼠标悬停在复选框的指示器上时如何设置皮肤。默认情况下，它们没有与之关联的皮肤/图像。此皮肤仅在鼠标悬停复选框时才会出现。

为了在鼠标悬停在指示器上时为指示器添加皮肤，我们必须更改样式表代码。下面是样式表代码。

QCheckBox::indicator: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 the check-box
        checkbox1 = QCheckBox('Geek ?', self)
  
        # setting geometry of check box
        checkbox1.setGeometry(200, 150, 100, 40)
  
        # setting tri-state check box
        checkbox1.setTristate(True)
  
        # changing style sheet code of check box
        # adding skin to indicator when it mouse hover over it
        checkbox1.setStyleSheet("QCheckBox::indicator: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())

输出 ：
