PyQt5 - 未选中状态下按下复选框的背景颜色

在本文中,我们将了解如何在未选中状态下按下复选框时为其设置颜色。默认情况下,复选框的标签部分没有设置按下颜色,尽管默认情况下,指示器在按下时具有浅蓝色背景色。

为了在未选中状态下按下复选框时为复选框添加背景颜色,我们必须编辑与复选框对象一起使用的样式表代码。下面是样式表代码。

QCheckBox::unchecked:pressed
{
background-color : pink;
}

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 pressed check box label part
        # when it is in unchecked state
        checkbox.setStyleSheet("QCheckBox::unchecked:pressed"
                               "{"
                               "background-color : pink;"
                               "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
