PyQt5 – 设置复选框被按下时的皮肤

在这篇文章中，我们将看到如何为处于选中状态并被按下的复选框的指示器设置皮肤。这个皮肤只在复选框被按下且其状态被选中时出现。

为了在复选框处于选中状态并被按下时给指示器添加皮肤，我们必须改变样式表代码。下面是样式表的代码。

QCheckBox::indicator:checked:pressed
{
border-image : url(image.png);
}

以下是实施情况。

# 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)
  
        # changing style sheet code of check box
        # adding skin to checked indicator when it get pressed
        checkbox1.setStyleSheet("QCheckBox::indicator:checked:pressed"
                                "{"
                                "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())
