PyQt5 – 鼠标悬停时皮肤到中间复选框

在本文中，我们将看到如何将皮肤设置为处于中间状态的复选框并将鼠标悬停在其上。默认情况下没有与图像关联的复选框，此皮肤仅在鼠标悬停时出现中间复选框。

中间（不确定）状态是处于选中状态和未选中状态之间的状态第三状态，可以借助setTristate方法添加到复选框。

为了设置皮肤，我们必须对复选框的样式表代码，下面是样式表代码。

QCheckBox::indeterminate::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 indeterminate check box when mouse hover over it
        checkbox1.setStyleSheet("QCheckBox::indeterminate: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 ：
