PyQt5 - 按下时设置复选框指示器的背景颜色

在本文中,我们将了解如何在按下复选框时为复选框的指示器设置背景颜色。默认情况下,按下复选框时会关联蓝色。此背景颜色只会出现复选框被按下。

为了给指示器复选框添加背景颜色,我们必须更改样式表代码,下面是执行此操作的样式表代码。

QCheckBox::indicator:pressed
{
background-color : lightgreen;
}

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)
  
        # changing style sheet code of check box
        # adding background color to indicator when it get pressed
        checkbox1.setStyleSheet("QCheckBox::indicator:pressed"
                                "{"
                                "background-color : lightgreen;"
                                "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
